Problems solved by technology

[0003] (1) The thickness of the inner and outer rings of the existing bearings is basically the same, so that the central diameter of the bearing is relatively high, the weight of the bearing is relatively heavy, and the service limit speed of the bearing is low, so it is impossible to use some high-speed, lightweight automotive transmission shafts superior
[0004] (2) The sealing ring generally adopts single-lip or double-lip sealing form, and the sealing performance is poor. The sealing ring is easy to loosen after long-term use, and the sealing performance is insufficient, which also shortens the service life of the bearing.

Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0018] see figure 1 , the high-speed lightweight transmission bearing 100 disclosed in the figure includes an outer ring 110, an inner ring 120, a cage 140, steel balls 130, sealing ring assemblies 150, 160, and the steel ball 130 is held on the outer ring 110 and the inner ring by the cage 140 120, the cage 140 is made of nylon, which further reduces the weight of the ultra-miniature bearing 100. The diameter of the st...

Abstract

The invention discloses a high-speed light-weight transmission bearing. The transmission bearing comprises an outer ring, an inner ring, a holder, steel balls, and a seal ring assembly; the steel balls are kept between the outer ring and the inner ring through the holder, the seal ring assembly is arranged between the outer ring and the inner ring; and the bearing is characterized in that the thickness of the outer ring is larger than that of the inner ring. The high-speed light-weight transmission bearing is suitable for use conditions of high-rotating-speed low-noise and light-weight car transmission shafts.

Description

technical field [0001] The invention belongs to the technical field of bearings, and in particular relates to a high-speed and lightweight transmission bearing. Background technique [0002] Existing bearings generally include an outer ring, an inner ring, a cage, steel balls, and a sealing ring. The steel ball is held between the outer ring and the inner ring through the cage, and the sealing ring is installed between the outer ring and the inner ring. This type of ultra-miniature bearing has the following problems: [0003] (1) The thickness of the inner and outer rings of the existing bearings is basically the same, so that the central diameter of the bearing is relatively high, the weight of the bearing is relatively heavy, and the service limit speed of the bearing is low, so it is impossible to use some high-speed, lightweight automotive transmission shafts superior. [0004] (2) The sealing ring generally adopts a single-lip or double-lip sealing form, and the seali...
