Description

Combined rear bearing outer cover Technical Field The utility model belongs to the field of bearing equipment, and particularly relates to a combined rear bearing outer cover. Background The rear bearing outer cover is an important part for protecting a bearing and maintaining normal operation of equipment in a mechanical transmission system, an optimization space exists on dust and water resistance of the rear bearing outer cover at the current part, because the structural design does not fully consider isolation of environmental media, foreign matters such as external dust, water vapor and the like easily enter a bearing cavity through gaps between the outer cover and a shaft or equipment shell, and meanwhile bearing lubricating grease also easily leaks from the gaps, so that poor lubrication and increased abrasion of the bearing are caused, and the service life of the equipment is shortened. The conventional coping method is to additionally add sealant or wind a sealing belt for gap filling during assembly, or replace an outer cover with a sealing groove and add a sealing ring during later equipment maintenance. However, when sealant or sealing tape is additionally added, the fit degree and durability of the sealing tape are greatly affected by material characteristics and mounting technology, ageing and cracking may occur after long-term use, so that sealing failure is caused, the outer cover with the sealing groove needs to be replaced, the outer cover structure is required to be redesigned, the mounting size is required to be adjusted, the equipment transformation cost and the downtime are possibly increased, and the suitability of the new structure and the original equipment parts also needs to be further verified, so that a new structure is required to be provided for solving the technical problems.
