Problems solved by technology

[0002] At present, when the electric drum on the market is running, the internal oil will accumulate to the oil seal cover through the bearing. Due to the structure of the drum, a local high pressure will be formed, which will increase the actual pressure at the oil seal cover and increase the actual pressure of the oil seal cover. pressure, which makes it easier for oil to leak from the oil seal cap
Furthermore, when installing or dismounting the electric drum currently on the market, other components on the rotating shaft outside the sealing chamber must be removed to push the oil seal along one end of the shaft to the preset oil seal installation position in the sealing chamber or by the opposite steps and In this way, it is not only time-consuming and labor-intensive, but also other parts of the equipment may be damaged when replacing the oil seal, which seriously affects the normal operation of the mechanical equipment and the efficiency and quality of production. The parts before the oil seal cover need to be disassembled first, and then the oil seal cover can be removed to take out the oil seal
The end cover of the traditional electric drum is non-embedded, so the structure is not compact enough, the seal is not tight enough, and the appearance is not beautiful enough

Embodiment

[0030] A new type of oil-leakage-proof, easy-to-assemble electric drum, characterized in that it includes a drum 1, an end cover 3 that is adaptively arranged at the end of the drum and sleeved on the rotating shaft 11 of the drum through a bearing 2, and a sleeve The oil seal assembly arranged on the rotating shaft and matched with the end cover is characterized in that the oil seal assembly includes an oil seal bushing 7 sleeved on the rotating shaft, which is arranged on the outside of the end cover and sleeved on the The cover 5 on the oil seal bush is set in the cover and sleeved on the skeleton oil seal 4 on the oil seal bush; the bearing includes an inner ring, an outer ring and a ball cavity between the inner and outer rings and Balls; the end cover includes a central mounting column sleeve 6 for cooperating with the installation of the bearing and the oil seal assembly, the mounting column sleeve includes a sleeve body 61 and a sleeve cavity 62, and the bearing is arra...

Embodiment 2

[0044] Such as figure 1 and figure 2 The difference from the above-mentioned embodiment is that the cover is provided with a positioning groove 54 that passes through the butt joint surface of the gland and the oil seal cover or uses the part of the butt joint surface as a groove wall on one side, that is, the gland is attached to the There are positioning grooves on the inner end surface of the oil seal cover and the oil seal cavity wall facing the frame oil seal, the positioning steps of the two frame oil seals are set in the positioning grooves, and the outer surface of the oil seal cover is set with the center of the rotating shaft as the axis. In the formed gland installation groove, a gland positioning convex ring adapted to the gland installation groove is provided on the inner side of the gland, and the positioning groove is arranged on the gland positioning convex ring. The oil seal cover cooperates with the end cover and the bearing to form a Z-shaped return flow ...

Abstract

The invention relates to the field of electric drums, in particular to a novel oil-leakage-proof and easy-to-assemble electric drum. It includes a drum, an end cover, and an oil seal assembly, and the oil seal assembly includes an oil seal bushing, a cover, and a skeleton oil seal; the bearing includes an inner ring, an outer ring, and a ball chamber and balls between the inner and outer rings; the end cover includes a mounting column The mounting column sleeve includes a sleeve body and a sleeve cavity, the bearing is arranged in the sleeve cavity, and the sleeve body is provided with a return hole communicating with the inner and outer spaces of the end cover, so The cover is provided with a return groove connecting the return hole and the ball cavity. In this application, a special return channel is formed through the cooperation of the return hole on the end cover and the return flow groove on the cover. This design allows the lubricating oil accumulated at the oil cover to flow back, reducing the oil pressure here.
