Abstract

The utility model discloses a chain with high fatigue high abrasion, its technical scheme: the chain is composed of a plurality of chain links, each chain link comprises an outer chain plate, an inner attached plate, a sleeve, a roller, an inner spring seat, an outer spring seat and a pin shaft, the sleeve is connected outside the pin shaft, the rollers are arranged at two ends of the pin shaft, the inner spring seats are installed between the inner chain plates, the outer spring seats are installed between the outer chain plates, and the outer chain plates, the inner chain plates and the inner attached plates are alternately connected through the pin shafts to form a chain whole. The holistic structural design of chain is reasonable reliable, sets up the axle sleeve between round pin axle and gyro wheel, through clearance fit, under the lubricated condition of refueling, the axle sleeve has played slide bearing's effect, and the adaptation has ensured whole chain high-speed even running at high-speed operation. The wear resistance of the chain is improved by adopting high-quality alloy steel.

Description

Chain with high fatigue and high wear resistance

Technical Field

The utility model belongs to the technical field of the chain, concretely relates to chain with high fatigue high wear resistance.

Background

The currently used known chains have the following disadvantages: the fatigue resistance of the chain is poor, the chain needs to be replaced frequently, otherwise, the chain is in fatigue fracture due to the severe use environment, and the chain is affected. The use unbalance loading and the faster occasion of speed of this product because structural design is unreasonable, the axle sleeve wearing phenomenon often appears in the chain, and both sides chain wearing and tearing are asynchronous, lead to one side chain off tracking, influence equipment normal operating to can't satisfy the chain operation requirement.

SUMMERY OF THE UTILITY MODEL

For solving the above-mentioned problem that exists among the prior art, the utility model provides a chain with high fatigue high wear resistance has tired, wear-resisting advantage.

In order to achieve the above object, the utility model provides a following technical scheme:

the chain with high fatigue and high wear resistance comprises a plurality of chain links, wherein each chain link comprises an outer chain plate, an inner attached plate, a sleeve, a roller, an inner spring seat, an outer spring seat and a pin shaft, the sleeve is connected to the outside of the pin shaft, the rollers are arranged at two ends of the pin shaft, the inner spring seats are installed between the inner chain plates, the outer spring seats are installed between the outer chain plates, and the outer chain plates, the inner chain plates and the inner attached plates are alternately connected through the pin shafts to form a whole chain.

Preferably, a shaft sleeve is arranged between the pin shaft and the roller. Through clearance fit, under the lubricated condition of oiling, the axle sleeve has played slide bearing's effect, and the adaptation has ensured the high-speed even running of whole chain at high-speed operation.

Preferably, the outer end of the pin shaft is provided with a gasket A at one side of the roller, and a gasket B is sleeved on the pin shaft between the outer chain plate and the other side of the roller.

Preferably, the inner attached plate is made of high-quality alloy steel, so that the anti-fatigue property of the chain plate is improved.

Preferably, the pin shaft, the shaft sleeve and the sleeve are made of high-quality alloy steel, so that the wear resistance of the product is improved.

Has the advantages that:

the holistic structural design of chain is reasonable reliable, sets up the axle sleeve between round pin axle and gyro wheel, through clearance fit, under the lubricated condition of refueling, the axle sleeve has played slide bearing's effect, and the adaptation has ensured whole chain high-speed even running at high-speed operation. The wear resistance of the chain is improved by adopting high-quality alloy steel.
