Embodiment Construction

[0017] Specific embodiments of the present invention are described with reference to the accompanying drawings.

[0018] as attached figure 1 As shown, the parts of the bearing of the present invention include an outer ring 1, an inner ring 6, a moving retaining ring 2, a cage 3, and a roller 5, and the cage 3 can be a brass entity. An oil groove 8 is arranged on the center line of the outer ring 1, and six oil holes 9 are evenly distributed on the oil groove 8; the angle of the small rib 7 of the inner ring is larger than the contact angle 30' of the bearing.

[0019] as attached figure 2 , 3 As shown, the outer diameter of the active retaining ring 2 is designed as a concentric circle smaller than the raceway diameter of the outer ring, and the dimension L between its two sides is smaller than the minimum inner diameter of the outer ring 1 . The end face of the retaining ring 2 during the activity is an oblique end face.

[0020] as attached Figure 4 As shown, the end...

Abstract

The invention discloses a light and narrow series double-row self-aligning roller bearing with a solid cage, the parts of which include an outer ring (1), an inner ring (6), a movable retaining ring (2) and a cage (3) , roller (5). An oil groove (8) is set on the center line of the outer ring (1), and oil holes (9) are evenly distributed on the oil groove (8); the angle of the small rib (7) of the inner ring is greater than the contact angle of the bearing by 30'; The outer diameter of the ring (2) is a concentric circle smaller than the raceway diameter of the outer ring (1), and the dimension (L) between its two sides is smaller than the minimum inner diameter of the outer ring (1). The invention has the characteristics of stable operation, high reliability, good lubricating performance, flexible rotation, short manufacturing cycle, low cost and the like.

Description

technical field [0001] The invention belongs to a roller bearing, and mainly relates to a structure type of a light and narrow series double-row self-aligning roller bearing with a solid cage. Background technique [0002] At present, the cages of my country's light and narrow series double-row spherical roller bearings adopt two structural types: steel plate stamping and brass solid. [0003] 1. Steel stamping cage: The stamping cage is divided into two types: active retaining ring guide and outer ring raceway guide. Due to the high cost of the cage mold and the long manufacturing cycle, it cannot meet the requirements of small batches and short delivery times. [0004] 2. Brass solid cage: a double-claw brass solid cage guided by a movable retaining ring. Due to the thin thickness and poor strength of the bottom of the cage, it cannot meet the design requirements of the light and narrow series of small-size bearings. Contents of the invention [0005] The purpose of t...
