Description

Technical Field

[0001] The present invention relates to the technical field of chain equipment, in particular to an energy-absorbing and stable sprocket. Background Art

[0002] Sprockets can be divided into various types based on their functions and uses, such as driving sprockets, driven sprockets, and idler sprockets. Each type of sprocket plays a specific role in the transmission system. As a key component in mechanical transmission, sprockets have a wide range of applications and diverse structural forms. When selecting and using sprockets, it is necessary to comprehensively consider the specific transmission requirements and usage environment to ensure the stability and reliability of the transmission system.

[0003] During the use of traditional sprockets, due to the need for stable transmission, the force-bearing positions are mostly fixed. Both the outer wall of the sprocket and the inner wall of the sprocket hole are subjected to unbalanced forces, which can easily cause the local area to be affected by unbalanced forces for a long time, affecting the overall working state and even the service life. Summary of the Invention

[0004] (1) Technical problems solved In response to the deficiencies of the prior art, the present invention provides an energy-absorbing and stable sprocket, which solves the problem that a local area is subjected to long-term unbalanced forces, which affects the overall working state and even the service life.

[0005] (2) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: an energy-absorbing and stable sprocket, comprising a sprocket body, a sprocket hole and teeth, a plurality of energy transmission grooves are opened inside the sprocket body, and the plurality of energy transmission grooves are distributed in a ring array, and two adjacent energy transmission grooves are connected by a transmission channel, and an energy transmission piston plate and a negative pressure piston plate are provided inside the energy transmission groove, and the side walls of the plurality of energy transmission piston plates away from the negative pressure piston plate are fixedly connected to the transmission shaft, and one end of the transmission shaft away from the energy transmission piston plate passes through the sprocket body and extends to the inside of the sprocket hole and is fixedly connected to the inner pressure arc plate, and the side walls of the plurality of negative pressure piston plates away from the energy transmission piston plate are fixedly connected to the negative pressure shaft, and one end of the negative pressure shaft away from the negative pressure piston plate passes through the sprocket body and extends to the outside thereof and is fixedly connected to the teeth.

[0006] Preferably, the interior of the energy transfer groove and the transmission channel and between the energy transfer piston plate and the negative pressure piston plate are filled with hydraulic oil.

[0007] Working principle: During use, when the sprocket is in working state, especially in high-load state, when the chain gives the sprocket a large load through the teeth, the teeth will transfer the energy through the negative pressure shaft and the negative pressure piston plate through the filled hydraulic oil to the internal pressure arc plate inside each tooth, thereby achieving the effect of energy sharing. At the same time, it can also be fed back to the locking between the sprocket and the support, improving the locking effect and ensuring the operation stability under large load conditions. When the internal pressure arc plate inside the sprocket hole is subjected to high pressure, it will also transfer energy to each internal pressure arc plate and strengthen the locking state of the chain and teeth through negative pressure, which can achieve dynamic energy sharing while also realizing feedback through internal and external cooperation to improve operation stability.

[0008] (3) Beneficial effects The present invention provides an energy-absorbing and stable sprocket. It has the following beneficial effects: 1. For this energy-absorbing and stable sprocket, when the chain applies a large load to the sprocket through the teeth, the teeth will transfer the energy to the internal pressure arc plate inside each tooth through the negative pressure shaft and the negative pressure piston plate through the filled hydraulic oil, thereby achieving the effect of energy sharing. At the same time, it can also be fed back to the locking between the sprocket and the support, improving the locking effect and ensuring the operating stability under large load conditions.

[0009] 2. When the internal pressure arc plates inside the sprocket hole are subjected to high pressure, this energy-absorbing and stable sprocket will also transfer energy to each internal pressure arc plate and strengthen the locking state of the chain and teeth through negative pressure. While realizing dynamic energy sharing, it can also realize feedback through internal and external coordination to improve operational stability. BRIEF DESCRIPTION OF THE DRAWINGS
