Description

Technical Field

[0001] The invention relates to the technical field of chain equipment, in particular to a weather-resistant and high-stability chain. Background Art

[0002] The working principle of the chain is mainly to transmit power or achieve other functions through the relative movement between the chain links. In the transmission chain, the power is usually transmitted from the driving wheel to the chain, and then the chain transmits the power to the driven wheel. The lifting chain suspends and pulls the heavy objects through the flexibility and strength of the chain links. The conveyor chain transports materials through the continuous movement of the chain links.

[0003] During the operation of the chain, due to its high lightness and uncertain high-load stress state, the sleeve and the pin are very easy to wear, which affects its service life. At the same time, the tissue exposed on the grinding surface is very easy to rust, reducing the weather resistance of the component. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a weather-resistant and high-stability chain, which solves the problem that during the operation of the chain, due to its high lightness and uncertain high-load stress state, the sleeve and the pin shaft are extremely easy to wear, thereby affecting its service life, and the tissue exposed on the grinding surface is extremely easy to rust, thereby reducing the weather resistance of the component.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a weather-resistant and high-stability chain, comprising an inner link plate, an outer link plate, a pin shaft, a sleeve and a chain plate hole, the side wall of the sleeve being provided with a plurality of oil storage channels, two negative pressure slides are arranged inside the plurality of oil storage channels, the opposite side walls of the two negative pressure slides located inside the same oil storage channel are fixedly connected with a pressure transmission plate, the upper surface of the pressure transmission plate is sloped, the opposite side walls of the two negative pressure slides located inside the same oil storage channel are fixedly connected with a return spring, the end of the return spring away from the negative pressure slide is fixedly connected to the inner wall of the oil storage channel, the oil storage channel is provided with a plurality of oil holes at a position close to the inner wall of the sleeve and is connected with the inner wall of the sleeve, the inner wall of the sleeve is provided with a plurality of card interfaces, the plurality of card interfaces are respectively connected with the middle positions of the plurality of oil storage channels, and the interiors of the plurality of card interfaces are rotatably carded with negative pressure rolling balls.

[0006] Preferably, a plurality of small oil outlet holes are arranged around the chain plate hole of the inner chain plate, and the plurality of small oil outlet holes located around the same chain plate hole are distributed in a ring array.

[0007] Working principle: When in use, in the working state of the chain, due to the relative movement between the pin and the sleeve, when the pin exerts negative pressure on the negative pressure rolling ball on the inner wall of the sleeve, it will sink into the inside of the oil storage channel and squeeze the pressure transmission plates on both sides. Since the upper surface of the pressure transmission plate is sloped, when the negative pressure rolling ball squeezes the two pressure transmission plates, the two pressure transmission plates will drive the two negative pressure slide plates to slide along the inner wall of the oil storage channel, and then squeeze the oil storage cotton filled inside, and oil seeps out through the oil hole. In conjunction with the movement of the pin itself, the pin surface and the inside of the sleeve can be lubricated to achieve the effect of internal lubrication, which can reduce the exposure of the contact layer and the subsequent rusting, thereby improving the weather resistance of the chain itself. In the process of repeated movement of the pin, since there are multiple oil outlet holes around the chain plate hole of the inner chain plate, the movement of the pin will throw the lubricating oil onto the inner chain plate, and the inner chain plate and the friction caused by the relative movement between the outer chain plate can also be lubricated through the oil outlet holes, thereby achieving a further lubrication and maintenance effect.

[0008] (III) Beneficial effects The present invention provides a weather-resistant high-stability chain, which has the following beneficial effects: 1. For this weather-resistant and high-stability chain, when the negative-pressure ball squeezes the two pressure transmission plates, the two pressure transmission plates will drive the two negative-pressure slide plates to slide along the inner wall of the oil storage channel, thereby squeezing the oil storage cotton filled inside, and oil seeping out through the oil holes. In conjunction with the movement of the pin shaft itself, the pin shaft surface and the inside of the sleeve can be lubricated to achieve the effect of internal lubrication, which can reduce the exposure of the contact layer and the subsequent rusting phenomenon, thereby improving the weather resistance of the chain itself.

[0009] 2. This weather-resistant and high-stability chain has multiple oil outlet holes around the chain plate holes of the inner chain plate. The movement of the pin will throw the lubricating oil onto the inner chain plate. The friction caused by the relative movement between the inner chain plate and the outer chain plate can also be lubricated through the oil outlet holes, achieving a further lubrication and maintenance effect.
