Description

A kind of high accuracy roller bearing

Technical field

This utility model relates to a kind of roller bearing, especially a kind of high accuracy roller bearing.

Background technology

It is currently used for the roller bearing being sleeved in the rotating shaft of Large-Scale Equipment, as shown in Figure 1, including inner ring 1, outer ring 2, steel ball 3, retainer 4, sealing ring 5, dust cap 6 and trip bolt 7, outer ring sleeve is contained in outside inner ring, is respectively provided with a steel ball groove 8 at outer ring inwall and interior ring outer wall；Steel ball is arranged in the groove between inner ring and outer ring by retainer, is respectively equipped with sealing ring and dust cap from inside to outside in retainer both sides, and trip bolt arranges inner ring one end；After this roller bearing is sleeved on the rotating shaft of Large-Scale Equipment, by trip bolt, bearing is locked with rotating shaft；In rotating shaft work running, easily countershaft produces damage, and in fastener cycle undue force, and owing to steel ball is linear to the active force of inner ring, can not fit tightly between inwall and the rotating shaft of inner ring after easily making bearing install, thus make inner ring be deformed, thus easily make inner ring wear and tear, affect service precision and the life-span of bearing.

Summary of the invention

For disadvantages mentioned above, the purpose of this utility model is to provide a kind of high accuracy roller bearing that can improve bearing service precision and life-span.

Technology contents of the present utility model is: a kind of high accuracy roller bearing, it is characterised in that its inner ring, outer ring, ball, retainer, sealing ring, ring for fixing, clamp ring and fixing nut；Ball is dolioform；Outer ring sleeve is contained in outside inner ring one end, and two row's balls are arranged between inner ring and outer ring by retainer, and the outer ring inwall corresponding with ball is indent waist arc, the interior ring outer wall behaviour word arc corresponding with ball；It is provided with a sealing ring between inner ring and outer ring outside ball；Ring for fixing is fixed on the inner ring other end, and clamp ring is sleeved on the inner ring outside ring for fixing, and clamp ring inwall is cone, and the port outer wall of the inner ring corresponding with clamp ring is cone, and the port of the inner ring corresponding with clamp ring is uniformly provided with some otch；Ring for fixing is provided with some fixing holes, is provided with some fixing holes through hole one to one in clamp ring, in fixing hole, connect one by through hole and fix nut.

Even if unclamping for convenience of bearing is dismantled from rotating shaft clamp ring, it also includes dismantling nut, is provided with some removal holes in clamp ring, and dismounting nut is arranged in removal hole.

This utility model is the most advantageously, this utility model is by being set to ball dolioform and being set to two rows, so that ball is face shape to the active force of bearing inner race, fit tightly between inwall and the rotating shaft of inner ring after bearing can be made to install, simultaneously when outer ring occurs skew, ball in the trickle movement of the catch cropping of inner ring Yu outer ring, thus can not affect inner ring, improve the service precision of bearing, it is possible to reduce noise；This utility model makes bearing inner ring locking in rotating shaft by clamp ring, also makes inner ring not be deformed, decreases the abrasion of inner ring, improves service precision and the life-span of bearing.

Specific embodiment

As shown in Figure 2, Figure 3 and Figure 4, a kind of high accuracy roller bearing, it is characterised in that its inner ring 11, outer ring 12, ball 13, retainer 14, sealing ring 15, ring for fixing 16, clamp ring 17, fixing nut 18 and dismounting nut 19；Ball 13 is dolioform；Outer ring 12 is sleeved on outside inner ring 11 one end, and two row's balls 13 are arranged between inner ring 11 and outer ring 12 by retainer 14, and outer ring 12 inwall corresponding with ball 13 is indent waist arc, the interior ring outer wall behaviour word arc corresponding with ball 13；It is provided with a sealing ring 15 between inner ring 11 and outer ring 12 outside ball 13；Ring for fixing 16 is fixed on inner ring 11 other end, clamp ring 17 is sleeved on the inner ring 11 outside ring for fixing 16, clamp ring 17 inwall is cone, and the port outer wall of the inner ring 11 corresponding with clamp ring 17 is cone, and the port of the inner ring 11 corresponding with clamp ring 17 is uniformly provided with some otch 11.1；Ring for fixing 16 is provided with some fixing holes 16.1, it is provided with some fixing hole 16.1 through hole 17.1 one to one in clamp ring 17, clamp ring 17 is provided with some removal holes 17.2, connecting one in fixing hole 16.1 by through hole 17.1 and fix nut 18, dismounting nut 19 is arranged in removal hole 17.2.

Operation principle of the present utility model is, when bearing is installed, bearing is sleeved in rotating shaft by inner ring 11, is then tightened by fixing nut 18, clamp ring 17 tighten up the inner ring 11 being provided with otch 11.1, thus bearing is fixed in rotating shaft, when dismantling bearing, first unclamp fixing nut 18, then withstand on ring for fixing 16 by the dismounting nut 19 in removal hole 17.2, thus first clamp ring 17 is unloaded from inner ring 11, thus can facilitate bearing removal.
