Abstract
The invention discloses a double-row self-aligning roller bearing which belongs to the light and narrow series and has a solid cage. The parts of the bearing include an outer ring (1), an inner ring (6), a movable middle retaining ring (2), a cage (3) and rollers (5), wherein, a lubricator groove (8) with uniformly distributed lubricator holes (9) is arranged on the central line of the outer ring (1); the angle of the small collar (7) of the inner ring is thirty minutes larger than the contact angle of the bearing; the outer diameter of the movable middle retaining ring (2) is concentric circle smaller than the diameter of the raceway of the outer ring (1), the length (L) between two sides is shorter than the minimum inner diameter of the outer ring (1). The invention has the advantages of stable operation, high reliability, excellent lubricating performance, flexible rotation, short manufacture cycle, low cost, etc.
Description
Technical field
The invention belongs to a kind of roller bearing, relate generally to a kind of light and narrow series band solid cage type double-row self-aligning roller bearing structural type.
Background technique
At present, its retainer of China's light and narrow series double-row self-aligning roller bearing adopts steel plate punching press and two kinds of structural types of brass entity.
1. steel plate pressing cage: pressing cage divides movable guide ring guiding and outer ring raceway to guide two kinds of patterns again.Because retainer die cost height and manufacturing cycle are long, can not satisfy small lot, short requirement at delivery date.
2. brass solid cage: two claw type brass solid cages of employing activity guide ring guiding.The thin thickness because retainer is revealed all the details, intensity difference can not satisfy the designing requirement of light and narrow series small size section bearing.
Summary of the invention
The purpose of this invention is to provide a kind of light and narrow series band solid cage type double-row self-aligning roller bearing, remedied the deficiency of above-mentioned two kinds of bearing structures, have characteristics such as running is steady, reliability is high, greasy property good, rotation is flexible.
Purpose of the present invention can adopt following technological scheme to realize: its bearing parts comprises outer ring, inner ring, movable guide ring and brass solid cage, roller.On the center line of outer ring, oil groove is set, on oil groove, is evenly equipped with six oilholes; The angle of the little rib of inner ring is greater than the wrapping angle 30 ' of bearing; The external diameter of movable guide ring is designed to the concentric circle less than the outer ring raceway diameter, and the size L between its both sides is less than the outer ring minimum diameter.
The end face of roller is the ball basal plane, and movable guide ring is an angled end-face.Retainer pocket hole is that face contacts with roller.The end face of retainer is provided with the plane of a gradient, and itself and center, pocket hole are 90 °.
By last structure as can be seen, the angle of the little rib of inner ring of the present invention's design is beneficial to packing into of roller greater than the wrapping angle 30 ' of bearing.With the end face design balling-up basal plane of rolling element, movable guide ring is an angled end-face, realizes that the rolling element end face contacts with movable guide ring rib point, reduces the frictional force of rolling element and movable guide ring rib.The external diameter of movable guide ring is designed to be slightly less than the concentric circle of outer ring raceway diameter, and the size L between its both sides is less than the outer ring minimum diameter, with entering of convenient installation and lubricating grease.Retainer pocket hole is that face contacts with roller, the held stationary running.Be 90 ° plane in α angle of retainer end face car and center, pocket hole, can make things convenient for the location processing of drill bit, to guarantee the position degree in each pocket hole.In sum, the present invention has characteristics such as running is steady, reliability is high, greasy property good, rotation is flexible, the manufacturing cycle is short, cost is low.

Embodiment
In conjunction with the accompanying drawings, specific embodiments of the invention are described.
As shown in Figure 1, its part of bearing of the present invention comprises outer ring 1, inner ring 6, movable guide ring 2 and retainer 3, roller 5, and retainer 3 can adopt the brass entity.Oil groove 8 is set on the center line of outer ring 1, on oil groove 8, is evenly equipped with six oilholes 9; The angle of the little rib 7 of inner ring is greater than the wrapping angle 30 ' of bearing.
Shown in accompanying drawing 2,3, the external diameter of movable guide ring 2 is designed to the concentric circle less than the outer ring raceway diameter, and the size L between its both sides is less than outer ring 1 minimum diameter.The end face of movable guide ring 2 is an angled end-face.
As shown in Figure 4, the end face of roller 5 is the ball basal plane, optimizes the shape in retainer pocket hole, strengthens the intensity that retainer is revealed all the details, and adopts the special-purpose tack milling cutter processing pocket hole identical with the roller bus, and retainer pocket hole is contacted for face with roller 5.
As shown in Figure 5, be 90 tapered plane 4 in one in retainer end face car with center, pocket hole.
Shown in accompanying drawing 6,7, when the wall thickness of movable guide ring during less than 5mm, can cancellation activity guide ring, make retainer directly be with guide ring, size L installs and the entering of lubricating grease with convenient less than the outer ring minimum diameter between its both sides.
For small size section bearing, the design size of inner ring centre rib can be lower than the size of two little ribs.
