Leaf Chains are made for high load, slow velocity stress linkage applications. Generally these are specifi ed for reciprocating movement lifting products such as fork lifts or cranes. These chains are normally provided to a specifi c length and are connected to a clevis block at every finish. The clevis may well accommodate male ends (within or often called “articulating” hyperlinks) or female ends (outside or even the backlinks about the pin link) as essential (see illustration under)
Leaf chains can be found in 3 series; AL (light duty), BL (hefty duty), or LL (European typical). For new selections we suggest the BL series in preference to your AL series since the latter has been discontinued being a recognized ASME/ANSI typical series chain. BL series chains are created in accordance with all the ASME/ANSI B29.8 American Leaf Chain Common. LL series chains are developed in accordance with all the ISO 606 international leaf chain typical.
A chain with an even number of pitches generally has a one male and one female end. It truly is extra common to have the chain possess an odd quantity of pitches during which situation the both ends will probably be both male (most typical) or female (less com-mon). When ordering lengths with an odd quantity of pitches male ends are supplied except if otherwise mentioned. Clevis pins, commonly with cotters at every single finish, are utilised to connect male chain ends to female clevis blocks. Chains with female ends are frequently (but not normally) connected on the clevis block that has a cottered style connecting website link. The connecting website link could be the female end part in this case.
Leaf Chain Choice
Utilize the following formula to confirm the selection of leaf chain:
Minimal Greatest Power > T x DF x SF
T: Calculated Maximum Chain Stress
DF: Duty Component
SF: Services Issue
Note that the optimum allowable chain pace for leaf chains is 100ft per minute.

Basic Properties of Maintenance Free of charge Roller Chain Solutions
Sintered Bushed (SL-Series) Chains
Oil impregnated powdered metal sintered bushings release oil to the chain joint as a result of friction developed in between the pin and bushing because the chain articulates in excess of the sprocket teeth. These chains are rollerless and so use thick sectioned powdered metal bushings which can hold a higher volume of oil.
PT Kind Roller Chains
Oil impregnated powdered metal sintered bushings release oil to your chain joint due to the friction produced concerning the pin and bushing as the chain articulates over the sprocket teeth. These chains possess rollers to smooth the action in excess of sprocket teeth. Roller hyperlink plates are a single dimension thicker to improve power. Side plates and pins have particular coatings to stop rust.
C-Type Roller Chains
Identical as above except that the side plates are all regular thickness. The power with the CS Form chains is lower than the PT Type but higher than the SL style. Attachments with common dimen-sions can be utilized for this series and so they can be typically made use of on small materials managing conveyors.
P-Ring Chains
Specifi ed on smaller sized pitch roller chains O-Ring chains make use of a rubber seal to maintain lubricating grease in whilst preventing the penetration of filth along with other contaminants to the pin/bush-ing bearing location.
Seal Guard Roller Chains
Specifi ed on greater pitch roller chains Seal Guard chains utilize a stainless steel seal to help keep lubricating grease in when stopping the penetration of filth and various contaminants in to the pin/bushing bearing spot.

Double Pitch roller chains are generated in accordance with all the ASME/ANSI B29.three (Transmission Series) and B29.4 (Conveyor Series) American roller chain standards. On the whole these chains are related to ASME/ANSI conventional products except that the pitch is double. They can be out there in Transmission Series, Conveyor Series with Regular (modest) Rollers and Conveyor Series with Significant (oversized) Rollers.
Transmission Series
This series is usually applied on drives with slow to moderate speeds, minimal chain loads and lengthy center distances. Side plates have a fi gure ?¡ã8?¡À contour. The chain amount is obtained by adding 2000 to the ASME/ANSI chain quantity as well as prefi x letter ?¡ãA?¡À. Note that some companies do not use a prefi x letter for this series so the chains could be represented as A2040, A2050 and so on. or 2040, 2050 and so on.
Conveyor Series with Normal (smaller) Rollers
This series is often made use of on light to reasonable load material dealing with conveyors with or devoid of attachment hyperlinks. The side plate contour is straight for improved sliding properties. Pitch sizes of 1-1/2?¡À and greater have ?¡ãHeavy?¡À series website link plates (i.e. link plates on the subsequent larger chain dimension. The chain variety is uncovered by including 2000 to the ASME/ANSI chain quantity and also the prefi x letter ?¡ãC?¡À. Chains using the ?¡ãheavy?¡À form side plates use a suffi x letter ?¡ãH?¡À.
Conveyor Series with Big (oversized) Rollers
These chains possess huge rollers to ensure that the chain rolls on the conveyor track minimizing friction. Chain numbers are found while in the same way as mentioned over except that the last digit about the chain number is transformed from ?¡ã0?¡À to ?¡ã2?¡À which denotes the significant roller.
Sprockets
Normally sprockets ought to be generated specially for these chains in accordance for the ASME/ANSI B29.three and B29.4 standards however, for Transmission Series and Conveyor Series with Common (smaller) Rollers, ASME/ANSI B29.one Typical roller chain sprockets may perhaps be utilized supplied the amount of teeth is 30 or a lot more.

The following methods should be employed to pick chain and sprocket sizes, establish the minimal center distance, and determine the length of chain needed in pitches. We’ll largely use Imperial units (this kind of as horsepower) on this part nonetheless Kilowatt Capability tables are available for each chain dimension from the preceding segment. The selection technique will be the exact same regardless of the units made use of.
Step one: Identify the Class of your Driven Load
Estimate which from the following very best characterizes the situation of the drive.
Uniform: Smooth operation. Minor or no shock loading. Soft get started up. Reasonable: Typical or moderate shock loading.
Heavy: Extreme shock loading. Frequent starts and stops.
Stage two: Determine the Services Factor
From Table one beneath ascertain the acceptable Service Component (SF) for your drive.
Step 3: Determine Design Power Requirement
Design and style Horsepower (DHP) = HP x SF (Imperial Units)
or
Design and style Kilowatt Electrical power (DKW) = KW x SF (Metric Units)
The Style Electrical power Necessity is equal for the motor (or engine) output electrical power times the Services Component obtained from Table one.
Phase 4: Make a Tentative Chain Variety
Produce a tentative choice of the expected chain dimension in the following method:
1. If employing Kilowatt energy – fi rst convert to horsepower for this stage by multiplying the motor Kilowatt rating by one.340 . . . This is essential since the brief selector chart is shown in horsepower.
2. Locate the Design and style Horsepower calculated in stage three by studying up the single, double, triple or quad chain columns. Draw a horizontal line as a result of this value.
3. Locate the rpm with the tiny sprocket within the horizontal axis of your chart. Draw a vertical line by means of this worth.
four. The intersection with the two lines must indicate the tentative chain variety.
Step 5: Pick the quantity of Teeth for the Modest Sprocket
The moment a tentative collection of the chain size is produced we have to decide the minimal variety of teeth demanded about the compact sprocket essential to transmit the Style and design Horsepower (DHP) or even the Style and design Kilowatt Power (DKW).
Stage six: Identify the quantity of Teeth for the Massive Sprocket
Make use of the following to calculate the number of teeth to the substantial sprocket:
N = (r / R) x n
The number of teeth around the large sprocket equals the rpm with the modest sprocket (r) divided from the wanted rpm with the huge sprocket (R) occasions the quantity of teeth on the modest sprocket. In case the sprocket is also massive to the area available then a number of strand chains of a smaller pitch really should be checked.
Stage seven: Ascertain the Minimal Shaft Center Distance
Utilize the following to calculate the minimal shaft center distance (in chain pitches):
C (min) = (2N + n) / six
The above is actually a guidebook only.
Step 8: Test the Final Assortment
Furthermore bear in mind of any probable interference or other room limitations that could exist and alter the assortment accordingly. Usually probably the most efficient/cost eff ective drive employs single strand chains. This really is simply because numerous strand sprockets are a lot more high priced and as is often ascertained by the multi-strand elements the chains grow to be significantly less effi cient in transmitting energy as the quantity of strands increases. It is actually therefore typically ideal to specify single strand chains every time possible
Phase 9: Identify the Length of Chain in Pitches
Utilize the following to calculate the length with the chain (L) in pitches:
L = ((N + n) / two) + (2C) + (K / C)
Values for “K” can be discovered in Table four on web page 43. Try to remember that
C is definitely the shaft center distance provided in pitches of chain (not inches or millimeters and so forth). When the shaft center distance is regarded inside a unit of length the value C is obtained by dividing the chain pitch (in the similar unit) by the shaft centers.
C = Shaft Centers (inches) / Chain Pitch (inches)
or
C = Shaft Centers (millimeters) / Chain Pitch (millimeters)
Note that whenever probable it is greatest to utilize an even number of pitches so as to keep away from the use of an off set hyperlink. Off sets will not possess the exact same load carrying capability since the base chain and really should be prevented if feasible.
