Abstract

The invention discloses a stop piece for a chain of a gearbox of a field management machine. The stop piece is used for preventing a transmission chain in the gearbox from scratching a gearbox shell, is arranged on each of the two sides of the transmission chain on the inner side of the gearbox shell, and comprises a stop piece body made from an elastic material, wherein the side, close to the transmission chain, of the stop piece body is an outer convex arc edge; a fixed device is arranged between the stop piece body and the gearbox shell. When the transmission chain is loosened in a transmission process, tightening force on the transmission chain can be effectively formed by the stop piece body, so that the transmission chain is prevented from vibrating, mutual scratches between the transmission chain and the gearbox shell can be prevented, noise produced in the transmission process of the chain is favorably reduced, and the stable running of the gearbox is further facilitated. In addition, the stop piece body is made from the elastic material, so that the stop piece is low in manufacturing cost, and also has the advantages of lightweight, small size and convenience in mounting.

Description

technical field

[0001] The invention relates to the technical field of gearbox transmission, in particular to a chain block of a gearbox for a garden management machine. Background technique

[0002] The existing pastoral management machine usually adopts two sets of gearboxes, one is the walking gearbox, which transmits the power shift of the engine to the walking power output shaft through chain transmission or gear transmission, and the other is the working gearbox, which can be used from The engine, or obtain power from the walking power output shaft, and then output the power to the working power output shaft through chain transmission or gear transmission. The chain transmission structure can effectively reduce the number of gears, reduce the weight of the gearbox, and reduce the manufacturing cost. However, due to the long chain, the chain will vibrate during the transmission process, and even easily scratch the gearbox case to generate various noises. Therefore awai...
