Background

The framework oil seal is a typical representative of an oil seal and has the function of isolating parts needing lubrication in a transmission part from the external environment so as not to allow the lubricating oil to leak. When the motor is assembled, if the bottom of the framework oil seal is assembled outwards, the sealing lip and the spring protecting lip are easy to turn over due to the fact that the inner diameter of the framework oil seal is smaller than the diameter of the shaft, the spring falls off, and the sealing effect cannot be achieved. Therefore, the motor assembly generally adopts inward assembly of the bottom of the framework oil seal.

When the bottom is towards the interior timing, for easy to assemble and raise the efficiency, generally install the skeleton oil blanket in the end cover earlier, the reassembling end cover. When the framework oil seal is packaged, if the framework oil seal is directly knocked by a metal bar or other heavy objects, the framework is easily deformed, and the structure of the framework oil seal is damaged; if the pressing machine is used for pressing, corresponding equipment needs to be purchased and corresponding tools need to be manufactured, the cost is high, and the application range is wide.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A framework oil seal installation sleeve for motor assembly comprises a handle 1, a baffle 2 and a compression ring 3, wherein the compression ring 3 is of a circular ring structure, the top surface of the baffle 2 is provided with the concentric handle 1, the bottom surface of the baffle 2 is provided with the concentric compression ring 3, the outer diameter of the compression ring 3 is smaller than that of the baffle 2, a stop groove 4 is formed between the outer ring of the compression ring 3 and the baffle 2, the bottom surface of the baffle 2 and the compression ring 3 are oppositely provided with an accommodating groove 5, the inner diameter of the accommodating groove 5 is the same as that of the compression ring 3, and the compression ring 3 is used for pressing a framework oil seal 6 into a motor end cover 7; during the installation, directly insert corresponding skeleton oil blanket inner area with telescopic clamping ring, then strike the handle with metal rod or other heavy objects, alright transmit power to the skeleton oil blanket for the accurate, quick end cover oil blanket room that enters into of skeleton oil blanket, easy operation, it is efficient.

As an improvement of the above technical scheme, corners of the end face of the compression ring 3 are of an inverted right-angle structure, and the outer ring of the stop groove 4 is of an inverted right-angle structure; the inverted-right-angle structure can facilitate the matching and the insertion of the sleeve and the framework oil seal.

As an improvement of the technical scheme, the handle 1, the baffle 2 and the press ring 3 are of an integrated cutting structure; the sleeve is formed by integral cutting, the coaxiality can be effectively ensured,

as an improvement of the above technical solution, the skeleton oil seal 6 includes a rubber sheath 61, a skeleton 62 and a spring 63, the rubber sheath 61 wraps the outside of the skeleton 62, a spring protection lip protrudes outwards from the middle of the rubber sheath 61, an outer ring protrudes outwards from the outer ring of the rubber sheath 61, the spring 63 is sleeved on the outer wall of the spring protection lip, an inner region 611 is formed between the spring protection lip and the outer ring, the press ring 3 extends into the inner region 611, the outer ring extends into the stop groove 4, and the baffle 2 abuts against the outer end surface of the outer ring; the sleeve is contradicted in the inner zone, can make the sleeve carry out stable support application of force to the skeleton oil blanket, improves the assembly effect of skeleton oil blanket, and is easy and simple to handle.
