Abstract
Description
Technical Field
[0001] The invention relates to the technical field of chain equipment, in particular to an improved chain bushing. Background Art
[0002] Chain bushing, also known as bushing roller chain, is a common transmission element widely used in various mechanical equipment. It consists of a series of bushings, rollers, pins, chain plates and other parts. Power and torque are transmitted by the rolling of bushings and rollers on pins.
[0003] During the use of traditional chain bushings, especially during movement, local areas are often subjected to excessive force, which in turn causes irreversible damage to the bushing and seriously affects the safety of equipment operation. Summary of the invention
[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides an improved chain sleeve, which solves the problem that during the use of traditional chain sleeves, especially during movement, local areas of the sleeve are often subjected to excessive force, thereby causing irreversible damage to the sleeve, which seriously affects the safety of equipment operation.
[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: an improved chain sleeve, comprising a sleeve body and a sleeve hole, an energy absorbing hydraulic cavity is opened inside the sleeve body, a group of energy transfer grooves and a group of energy absorption channels are connected to the side wall of the sleeve hole near the energy absorbing hydraulic cavity, the energy absorption channels and the energy transfer grooves are distributed in an interval manner, an energy absorbing plate is arranged inside the energy absorbing channel, the energy absorbing plate is fixedly connected with an energy absorbing shaft near the side wall of the sleeve hole, the energy absorbing shaft extends to the outside of the energy absorbing channel and is fixedly connected with a negative pressure plate at one end away from the energy absorbing plate, a connecting plate is arranged inside the energy transfer groove, the connecting plate is fixedly connected with a transmission shaft near the side wall of the sleeve hole, the transmission shaft extends to the outside of the energy transfer groove and is fixedly connected with an extrusion plate at one end away from the connecting plate, the extrusion plate is located between the negative pressure plates, and an oil storage sponge is arranged between the extrusion plate and the side wall of the sleeve hole.
[0006] Preferably, the oil storage sponge extends between the negative pressure plate and the side wall of the sleeve hole, and the size of the oil storage sponge is greater than the width of the extrusion plate and the negative pressure plate.
[0007] Working principle: During use, when the chain is in a high-power working state, when the pin shaft applies pressure by squeezing one of the negative pressure plates, the pressure generated will be transmitted to other identical structures through the energy-absorbing shaft, the energy-absorbing plate and the energy-absorbing hydraulic chamber. When the sleeve body itself is under pressure, the force on the sleeve is integral, so it can effectively avoid excessive damage caused by uneven force in local areas, thereby achieving effective protection of the contact surface of the inner wall of the sleeve. When the force is too large, as the chain moves, the pin shaft will squeeze the oil storage sponge, and then the lubricating oil stored in the oil-absorbing sponge will be smeared on the surface of the pin shaft through the gap between the squeezing plate and the negative pressure plate, which also plays a certain maintenance and lubrication role on the pin shaft itself.
[0008] (III) Beneficial effects The present invention provides an improved chain bushing, which has the following beneficial effects: 1. For the improved chain bushing, when the bushing body itself is subjected to pressure, the force on the bushing is integral, thus effectively avoiding excessive damage caused by uneven force in a local area, thereby achieving effective protection of the contact surface of the inner wall of the bushing.
[0009] 2. When the improved chain sleeve is subjected to excessive force, as the chain moves, the pin will squeeze the oil storage sponge, and then the lubricating oil stored in the oil absorption sponge will be smeared on the surface of the pin through the gap between the extrusion plate and the negative pressure plate, which also plays a certain maintenance and lubrication role on the pin itself.
