Common shapes and structures of marine sprockets for L28/32 diesel engine parts
The sprocket is one of the important parts in the chain drive. When buying it, you need to know its specific shape and structure, so that you can buy it correctly and use it.
Usually, the sprocket is composed of three parts: the ring gear, the wheel and the spokes. Common sprocket shapes are:
1. Single-piece single- and double-row sprocket.
2. Single flange type single and double row sprockets.
3. Double flange type single and double row sprockets.
The structure of the sprocket is roughly as follows:
1. The overall structure
It is generally used in the processing of single and double row, single and double flange sprockets with standard chain P=38.1 or less.
2. Welding structure
Mainly used in the processing of medium and large size single and double flange sprockets. When processing, the flange part adopts bar car to make convex shape. The ring gear part can be cut with a plate to process the outer diameter and the shaft hole, and one end of the hole is turned out and the welding groove is sleeved into the flange part for welding. When welding, both ends should be welded, using low-hydrogen electrode such as T506 electrode.
3. Casting sprocket
It is mainly used in the processing of large sprocket wheels. During processing, only the gear ring, flange end faces, outer and inner diameters and keyways are processed, and then the tooth profile is processed. The ring sprockets are all cast. There are generally two kinds of materials for casting sprocket, cast iron and cast steel such as HTl5O, HT2O0 and ZG310-570 (ZG45).
4. Forged sprocket
It is mainly used in the production of medium and large sprocket with large force. When forging marine diesel engine parts, whether it is single-flange or double-flange, they are generally forged into a convex shape, leaving enough machining allowance for the shaft hole, low material utilization, and high cost.
The above is the specific shape and structure, and consumers can choose according to their actual needs.
