Description

Technical Field

[0001] The invention relates to the technical field of chain equipment, in particular to a light and high-strength self-lubricating chain. Background Art

[0002] Chain is a common mechanical transmission element, usually composed of a series of metal rings or links connected to form a continuous, bendable and stretchable chain. It is widely used in various mechanical equipment and tools to transmit power, guide movement or hang objects. In addition, the chain needs regular maintenance and care during use, including cleaning, lubrication and checking the wear of chain links, pins and other parts. If the chain is broken, deformed or severely worn, it should be replaced in time to avoid safety accidents.

[0003] During the production process of the chain, a lot of lubricating oil needs to be applied, and periodic lubrication and maintenance are also required during the subsequent working process, especially for chains that work at high intensity. However, the maintenance process of traditional chains is relatively complicated. 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 lightweight and high-strength self-lubricating chain, which solves the problem that the maintenance process of traditional chains is relatively complicated.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a lightweight and high-strength self-lubricating chain, comprising a sleeve, a pin shaft, an inner link plate, a chain plate hole and an outer link plate, the inner link plate is provided with an oil storage mechanism on the side wall close to the outer link plate, the oil storage mechanism comprises a plurality of oil storage chambers, a plurality of the oil storage chambers are distributed around the chain plate hole, two adjacent oil storage chambers are connected through an oil storage channel, a plurality of the oil storage chambers are connected with the chain plate hole through an oil outlet hole, the interiors of a plurality of the oil storage chambers and the oil storage channels are filled with oil storage cotton, a plurality of the oil storage chambers and the oil storage channels are provided with compression springs, the compression springs extend to the outside of the oil storage chambers and the oil storage channels, the outer link plate is provided with a driving mechanism on the side wall close to the inner link plate, the driving mechanism comprises a plurality of driving protrusions, a plurality of the driving protrusions are connected to the outer chain The inner wall of the plate is rotatably connected, and multiple driving protrusions are distributed in a surrounding array around the chain plate hole. The inner wall of the inner chain plate is fixedly connected with a mounting ring, and the interior of the mounting ring is filled with oil storage cotton. The inner wall of the mounting ring is connected to multiple groups of oil release protrusions, and a single group of oil release protrusions is distributed in a ring array. The oil release protrusion is slidingly engaged with the inner side wall of the mounting ring, and the side wall of the oil release protrusion close to the inside of the mounting ring is fixedly connected with a negative pressure spring, and the end of the negative pressure spring away from the oil release protrusion is fixedly connected with a compression plate, and the compression plate is fitted with the oil storage cotton. The inner wall of the mounting ring is provided with multiple oil outlet channels, and the outer wall of the pin shaft is rotatably engaged with multiple groups of driving balls, and multiple driving balls in a single group of driving balls are distributed in a ring array, and two adjacent groups of oil release protrusions and driving balls are both staggered.

[0006] Working principle: During use, when the chain is transmitting, relative movement will occur between the inner chain plate and the outer chain plate, especially when the transmission direction changes, because the outer chain plate is provided with a driving mechanism near the side wall of the inner chain plate, and the inner chain plate is provided with an oil storage mechanism near the side wall of the outer chain plate, and the oil storage cavity and the oil storage channel in the oil storage mechanism are both provided with compression springs, and the compression springs extend to the outside of the oil storage cavity and the oil storage channel. When the two move relative to each other, the driving mechanism will compress the oil storage cotton through the compression spring, release the stored lubricating oil outward through the oil outlet hole, lubricate the friction between the chain plate and the pin shaft, lubricate the contact surface between the pin shaft and the chain plate from both ends, and reduce the friction. During the transmission process, the oil release protrusion will drive the oil release protrusion, the negative pressure spring and the compression plate to apply pressure to the oil storage cotton through the relative movement with the driving ball, and lubricate the pin shaft and the sleeve through the oil channel. The lubrication degree will improve the lubrication effect as the motion load increases, thereby achieving the effect of automatic lubrication, and lubricating the key stress points well.

[0007] (III) Beneficial effects The present invention provides a lightweight and high-strength self-lubricating chain, which has the following beneficial effects: 1. This lightweight and high-strength self-lubricating chain, when the chain is transmitting, there will be relative movement between the inner chain plate and the outer chain plate. When the two move relative to each other, the driving mechanism will compress the oil storage cotton through the compression spring, and release the stored lubricating oil outward through the oil outlet hole to lubricate the friction between the chain plate and the pin shaft, and lubricate the contact surface of the pin shaft and the chain plate from both ends to reduce the friction.

[0008] 2. During the transmission process of this lightweight and high-strength self-lubricating chain, the oil release protrusion will move relative to the driving ball, thereby driving the oil release protrusion, the negative pressure spring and the compression plate to apply pressure to the oil storage cotton, and lubricate the pin shaft and the sleeve through the oil channel. The degree of lubrication will increase with the increase of the motion load, thereby achieving the effect of automatic lubrication and lubricating the key stress points well.
