Description

Dustproof device of high-strength limit torque transmission arm Technical Field The utility model relates to the field of transmission arms, in particular to a dustproof device of a high-strength limit torque transmission arm. Background In modern industrial production and in many fields related to mechanical transmission, a high-strength limit torque transmission arm is widely applied to key equipment such as various large-scale mechanical equipment, automatic production lines and precise instruments, and the transmission arm needs to bear extremely high torque load in the operation process of the equipment so as to ensure efficient power transmission and normal operation of the equipment, and the high-strength limit torque transmission arm needs to be dustproof through a dustproof sleeve on a power transmission node of the transmission arm in a high-dust environment, so that the service life of the power transmission node of the transmission arm is prolonged. However, in the conventional high-strength limit torque transmission arm, dust prevention measures for the high-strength limit torque transmission arm have a number of drawbacks. On the one hand, most of the dust covers are of integral design, so that lubricating oil is added to the power transmission node of the transmission arm, the dust covers are required to be disassembled by means of tools, the lubricating oil can be added, and the efficiency of lubricating oil addition is affected. On the other hand, when the dust cover is damaged somewhere, need carry out the whole change to the dust cover, and then improve the cost that the dust cover was changed. For this reason, new solutions need to be designed to solve. Disclosure of utility model The utility model aims to overcome the defects of the prior art, adapt to the actual needs, and provide a dustproof device of a high-strength limit torque transmission arm, so as to solve the technical problems that most of the dustproof sleeves are integrally designed at present, so that lubricating oil is added to a power transmission node of the transmission arm, the dustproof sleeves are detached by means of tools, the lubricating oil can be added, and the efficiency of adding the lubricating oil is influenced. In order to achieve the aim of the utility model, the technical scheme adopted by the utility model is that the dustproof device of the high-strength limit torque transmission arm is designed and comprises the following components: The dismounting mechanism comprises a connecting cylinder fixedly connected to one end of the first rubber sleeve and a plug cylinder fixedly connected to one end of the second rubber sleeve, the connecting cylinder and the plug cylinder are arranged oppositely, a plug groove is formed in the plug cylinder, the plug groove is circular, and the connecting cylinder corresponds to the plug groove; and the mounting mechanism is used for mounting the first rubber sleeve and the second rubber sleeve. Preferably, the outside fixedly connected with spacing ring of connecting cylinder, the ring channel has all been seted up to the inner chamber both sides of spliced groove, the inside size of ring channel and the external dimension looks adaptation of spacing ring. Preferably, the installation mechanism is a metal clamp, and the metal clamp is respectively sleeved on the outer sides of the first rubber sleeve and the second rubber sleeve. Preferably, the outer side of the connecting cylinder is inlaid with a metal sleeve. Preferably, the distance from the bottom end of the inner cavity of the inserting groove to the annular groove is the same as the distance from the bottom end of the first rubber sleeve to the limiting ring.
