Chain Gear


1.Material: 

C45 Q235A 35# 15Cr S35C 304 316 etc.

 

2.Surface Treatment:

Blackening ,Zinc-plated ,Carburizing treatment  , Quenching treatment, drawing temper etc.

 

3.Application: 

Sprocket can be divided into active theory of sprocket and chain driven, active chain wheel through the form of a spline on the engine output shaft;Driven chain theory in mechanical equipment on the driving wheel, through the chain transfer power to the drive wheels, general active chain wheel is smaller than the driven chain theory, that can play a slow increase torsion effect .

 

4.Processing equipment: 

Hobbing machine, slotting machine , CNC lathes and other equipment.

 

5.Sprocket models: 

contains non-standard sprocket (custom) according to customer's drawings, standard sprocket (American standard and metric).

 

6.Package: 

Wooden Case/Container and pallet, or made-to-order


7.Introduction 

Has a derailleur gear of the bicycle light chain can buckle (or more precisely the separation in the side because of "riveting" first failure is normal), because the internal pin is not cylindrical, they are barrel shaped. The contact between the pin and the bushing is not a conventional line, but allows the dowel of the chain to pass through the Bush and, finally, the point of the roller, which eventually causes the chain to buckle. The structure of this form is necessary, because the action of the shifting of the transmission form to chain lateral bending and torsion, but this can happen on the bicycle chain this narrow and relatively large free length of flexible.

Since parallel pins have greater wear surfaces in contact with bushings, the sprocket faults are not only the problem of wheel gear systems (e.g., Bendix 2 speed, Sturmey-Archer, AW). The hub gear system also allows the complete enclosure to greatly aid lubrication and prevent sanding.
