Henan roller chain chain

Roller chainUsing a common chain, and at the same time meshing with two side-by-side sprockets with the same number of teeth, chain couplings of different structural types, the main difference is the use of different chains.

The structural characteristics of the roller chain chain: the coupling chain structure is simple, easy to assemble and disassemble, no need to move the connected two shafts when disassembling, compact size, light weight, compensation ability, low installation accuracy requirements, long life, and cost Inferior.

Roller chain chain is a coupling chain, which is characterized by using a common chain to mesh with two parallel sprockets with the same number of teeth at the same time. In high-speed and heavy-duty power transmission, some couplings also have buffering and vibration reduction And improve the dynamic performance of the shafting.The coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft.The general power machine is mostly connected with the working machine by means of a coupling.

Inspection method of roller chain:

Roller chain chain elongation = judgment size-reference length / reference length *1

(1) In order to remove the clearance of the entire roller coupling chain, it is necessary to apply a certain degree of pulling tension to it to measure

(2) When measuring, in order to minimize the error, measure at 6-10 knots (link)

(3 Find the elongation length of the roller coupling chain. This value is compared with the use limit value of the chain elongation in the previous paragraph.

(4)丈量节数的滚子之间的内侧L1和外侧L2尺寸，以求出判定尺寸L=(L1L2)/2

Measure the elongation of the roller chain of the roller coupling:

(1) The roller coupling chain before measurement should stay for 1 min under the condition of applying a third of a small tensile load.

(2) Enclose the tested chain on two sprockets, and the upper and lower sides of the tested chain should be supported

(3) The chain is cleaned before measurement

(4) Measure the distance between the two sprockets

(5) When measuring, apply a defined measuring load on the roller coupling chain to make the upper and lower sides tensioned, and the sprocket should meet the normal toothing.

Repair method of roller chain of roller coupling:

(1) Whether the roller is cracked, damaged or excessively worn

(2) Whether the pin is deformed or rolled, embroidered

(3) Whether the joint is loose and deformed

(4) Whether there is abnormal noise or abnormal vibration during operation, and whether the lubrication condition of the roller coupling chain is good

(5) Whether the inner/outer chain pieces are deformed, cracked, or embroidered.
