Technical Field

The utility model belongs to the technical field of mechanical transmission part, concretely relates to gear.

Background

The gear is one of the common parts in mechanical products, and the gear is used as a transmission device, has a plurality of purposes and can be used for transmission, acceleration and deceleration and the like. In the prior art, the gear generates larger noise and larger friction when running, which affects the service life of the gear.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that to above-mentioned defect, provide a gear, simple structure, weight is lighter, can reduce the noise that produces because of the friction, and is lubricated effectual moreover, can increase of service life.

The utility model provides a technical scheme that its technical problem adopted as follows:

a gear comprises an inner disc and an outer disc, wherein the inner disc is provided with a shaft hole and a key groove connected with the shaft hole, and noise reduction cotton is filled in the inner disc; the middle part of the outer disc is of a hollow structure, disc teeth are arranged on the outer wall of the outer disc, a tooth groove is formed between every two adjacent disc teeth, an oil suction block is arranged in the tooth groove and is attached to the groove wall of the tooth groove, an oil cavity and a plurality of oil ducts are arranged in the outer disc, one end of each oil duct is communicated with the oil cavity, and the other end of each oil duct is located at the groove bottom of the tooth groove; the inner disc is arranged in the middle of the outer disc, and the inner disc is connected with the outer disc through a plurality of spokes.

Furthermore, the oil absorption block is made of polypropylene and is fixed at the bottom of the tooth groove and connected with the end part of the oil duct.

Further, the noise reduction cotton is a glass fiber cotton block.

Furthermore, an anti-abrasion layer is arranged on the outer wall of the disc tooth.

Furthermore, an oil filling hole communicated with the oil cavity is formed in the inner wall of the outer plate, and a sealing bolt is arranged in the oil filling hole.

The utility model has the advantages that:

(1) the utility model can effectively eliminate the noise generated by friction through the silencing cotton, and the inner disc and the outer disc are connected through a plurality of spokes, thus greatly reducing the weight of the gear; and through storing lubricating oil in the oil cavity, when the gear runs, lubricating oil can be discharged from the oil duct to the tooth's socket, thereby lubricate the plate tooth, in order to lengthen life, is equipped with the oil absorption piece in the tooth's socket, the oil absorption piece can slow down the velocity of flow of lubricating oil, and guide lubricating oil to the plate tooth through the oil absorption piece, in order to lubricate the plate tooth effectively.

(2) The utility model discloses be equipped with the abrasionproof layer on the outer wall of well dish tooth to increase its wearability, thereby prolong its life.

(3) The utility model discloses be equipped with the tank filler sleeve that is linked together with the oil pocket on the inner wall of well outer dish, be equipped with sealing bolt in this tank filler sleeve to add lubricating oil.
