Description

TECHNICAL FIELD

[0001] The utility model relates to bearing technical field, concretely is a double row angular contact ball bearing special for bionic robot dog. BACKGROUND

[0002] Bearing is an important spare part in contemporary mechanical equipment. Its main function is to support mechanical rotary body, reduce its friction coefficient in the movement process, and ensure its rotation precision. The early linear motion bearing form is to place a row of wood rods under a row of pry plates. Modern linear motion bearings use the same working principle, but sometimes use balls instead of rollers. The simplest rotary bearing is a bushing bearing, which is just a bushing clamped between the wheel and the axle. This design is later replaced by rolling bearings, which use many cylindrical rollers instead of the original bushing, and each roller acts like a separate wheel.

[0003] According to the patent authorization announcement number: CN219712047U proposes a double row angular contact ball bearing, relating to the field of double row angular contact ball bearings. The double row angular contact ball bearing includes an inner ring, balls, an outer ring, and a stamping retainer. The inner ring has balls on its side, and the outer ring has balls on its outside. The inner ring and the outer ring are fixedly connected with the stamping retainer. The double row angular contact ball bearing sets a detachable stamping retainer to install the balls. The inner raceway and the pressing strip install the balls between the inner ring and the outer ring to form a double row angular contact ball bearing. This bearing not only maintains complete functionality during use, but also allows for internal dust cleaning by disassembling the structure. Additionally, it allows for the replacement of easily damaged balls to reduce friction damage to the stamping retainer and ensure smooth operation of the double row angular contact ball bearing. Furthermore, replacing worn-out balls can extend the service life of the double row angular contact ball bearing and reduce the loss of the part.

[0004] However, the front and rear sealing rubber gaskets of the double row angular contact ball bearing in the prior art are usually clamped on the front and rear of the bearing. After long-term use, the front and rear sealing rubber gaskets are prone to loosen and fall off, affecting the installation stability of the front and rear sealing rubber gaskets and the sealing effect of the front and rear sealing rubber gaskets. Additionally, the inner ring of the bearing is smooth on the surface, making it difficult to store lubricating oil, which makes it difficult to lubricate for a long time, and the inner ring and the outer connecting shaft are prone to wear and damage, causing friction noise.
