Description

Technical Field

[0001] This utility model relates to the field of transmission roller technology, and in particular to a waterproof and dustproof chamfered grinding wheel rotor assembly. Background Technology

[0002] Automated production line conveyor equipment is a key infrastructure for achieving efficient and precise material transfer in modern industrial production. By integrating mechanical, electrical, and control technologies, it constructs an intelligent transmission network connecting various production stages. Automated production line conveyor equipment not only significantly improves material transfer efficiency and reduces labor costs, but also achieves intelligent monitoring and scheduling of the transmission process through deep integration with industrial control systems. This provides strong support for the efficient and stable operation of automated production lines and has been widely used in many industries such as automobile manufacturing, electronic assembly, and food processing.

[0003] In the prior art, due to the complex operating environment of the transmission equipment, the rotor assembly has poor sealing when running at high speed, making it susceptible to dust intrusion. This leads to lubrication failure between the internal mechanisms, increases wear between the mechanisms, reduces the service life of the transmission device, decreases the reliability of the equipment, and directly affects production efficiency. Therefore, in order to solve the above problems, this utility model proposes a waterproof and dustproof chamfered grinding wheel rotor assembly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a waterproof and dustproof chamfering grinding wheel rotor assembly. Through structural innovation and material process optimization, it solves the problems of poor sealing and rapid wear under high-speed operating conditions, significantly improving the reliability and production efficiency of the equipment. It is suitable for harsh industrial scenarios such as high-strength glass edging machines, and solves the problems of rotor assemblies in existing technologies being susceptible to dust intrusion and lubrication failure leading to short lifespan when operating at high speeds.

[0005] This utility model provides the following technical solution: a waterproof and dustproof chamfered grinding wheel rotor assembly, including a grinding wheel bearing housing. Three deep groove ball bearings are evenly arranged in the inner cavity of the grinding wheel bearing housing. The outer rings of the deep groove ball bearings are fixedly connected to the inner cavity of the grinding wheel bearing housing. A grinding wheel shaft is fixedly sleeved on the inner ring of the deep groove ball bearings. The grinding wheel shaft is movably sleeved on the grinding wheel bearing housing. A grinding wheel shaft seat cover is fixedly installed on the right side of the grinding wheel bearing housing. A multi-wedge pulley is fixedly sleeved on the right side of the grinding wheel shaft, located to the right of the grinding wheel bearing housing. The multi-wedge pulley is movably sleeved on the grinding wheel shaft seat cover. The rotating sleeve has a chamfered grinding wheel one on the left side of the grinding wheel bearing seat, and a chamfered grinding wheel two on the right side of the grinding wheel bearing seat. A multi-wedge pulley cover is fixedly installed on the right side of the grinding wheel shaft. The multi-wedge pulley cover is engaged with the right side of the multi-wedge pulley's inner cavity. Through structural innovation and material process optimization, the problems of poor sealing and rapid wear under high-speed conditions are solved. This makes the rotor less susceptible to dust intrusion during high-speed operation, avoids lubrication failure, and extends service life, significantly improving the reliability and production efficiency of the equipment. It is suitable for harsh industrial scenarios such as high-strength glass edging machines.

[0006] Preferably, the chamfered grinding wheel includes a roller, the right side of which has a groove, the groove being engaged with the left end of the grinding wheel shaft, the left side of the groove is fixedly connected with a pin, and the right side of the roller, located on both sides of the groove, is fixedly connected with pins two respectively. Compared with a large number of bolts, fixing with multiple sets of pins is beneficial to improving the disassembly and assembly efficiency of the device.

[0007] Preferably, both pin one and pin two are engaged with the left end of the grinding wheel shaft. Pin one and pin two are respectively provided with through holes three. A bolt is movably sleeved on the left end of the grinding wheel shaft. The bolt is engaged with the through hole three. Only one bolt is needed to fix the roller mechanism, avoiding a lot of time spent on fixing and facilitating the later maintenance of the device.

[0008] Preferably, the chamfered grinding wheel includes a roller, the roller having a through hole in the middle, and the roller having two through holes on both sides of the through hole. The through hole 1 is fitted to the left end of the grinding wheel shaft, and the through hole 2 is fitted to the pin 2. When installing the chamfered grinding wheel, first align the roller with the left end of the grinding wheel shaft, then snap the pin into the left end of the grinding wheel shaft, and finally fix it with bolts to achieve quick installation of the chamfered grinding wheel.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. By adopting a multi-layer combined sealing design, a radial labyrinth seal and a fluororubber dynamic sealing ring are set between the grinding wheel bearing housing and the grinding wheel shaft housing cover, which effectively isolates external dust and moisture from intrusion. The chamfered grinding wheel one and chamfered grinding wheel two form a self-cleaning guide channel through the conical surface cooperation, reducing the accumulation of grinding debris and further enhancing the sealing effect.

[0011] 2. The grinding wheel shaft is made of silicon nitride ceramic matrix composite material, and the surface is treated with ultra-precision grinding. It is equipped with high-precision deep groove ball bearings, which significantly reduces the coefficient of friction and thermal deformation, and supports speeds of over 20,000 rpm. The multi-wedge pulley is dynamically balanced and optimized with V-groove design to ensure transmission stability and reduce vibration and energy loss.

[0012] 3. The grinding wheel bearing housing and grinding wheel shaft are both made of titanium alloy TC4 with surface nitriding treatment, with a hardness greater than 8HRC, which has both high wear resistance and fatigue strength. The remaining components adopt a modular design, which is convenient for maintenance and replacement, and extends the overall service life to more than 10,000 hours.

[0013] 4. By setting pins and bolts, chamfered grinding wheel one and chamfered grinding wheel two can be quickly connected to the grinding wheel shaft, reducing exposed bolt holes, preventing dust and other impurities from adhering, reducing resistance when the rollers rotate, and ensuring stable operation of the roller rotor.
