Abstract
A kind of instrument of dismounting NU type cylinder roller bearing inner rings is made up of bolt (1), plane bearing (2), distending round nut (3), interior external conical sleeve (4), clamping round nut (5), distending tapered sleeve (6), dog link (7), the interior external conical sleeve is made of spring steel, it is and thermally treated, it is set to have enough elasticity, there is external screw thread on cylindrical and have outer cone, endoporus has inner cone, some bar grooves are provided with above, equipped with round nut is clamped on the external screw thread of interior external conical sleeve, hole is built with distending tapered sleeve；Distending round nut is housed on the external screw thread of the distending tapered sleeve, bolt is screwed with screwed hole, end face is equipped with plane bearing, interior external conical sleeve aperture is built with dog link, tighten distending round nut, distending tapered sleeve moves to left, after interior external conical sleeve reverse taper holes footpath increase, it is set to side inside roller bearing inner ring, unclamp distending round nut, tap bolt head, move to right external conical sleeve, tighten clamping round nut, reduce in interior external conical sleeve reverse taper holes footpath, tighten the end face that bolt withstands axle, cylinder roller bearing inner ring is pulled out, hand-held dog link, prevent that distending tapered sleeve rotates when tightening bolt.
Description
Technical field
Mechanical manufacturing field is the utility model is related to, Automatic manual transmission is related specifically to and repairs field.
Background technology
NU type cylinder roller bearing assembling structures as shown in figure 1, bearing inner race mounted in axle it is cylindrical on, outside with axle gear
Enclose spacing, outer ring and roller can be pulled down, because inner ring end diameter and axle external diameter are very close to being not easy to dismantle, with the method for percussion
When dismantling NU type cylinder roller bearing inner rings, not only arduously, and inner ring is easily damaged.
The content of the invention
The purpose of this utility model is the dismounting problem for solving NU type cylinder roller bearing inner rings, there is provided one kind is laborsaving simultaneously
The instrument of NU type cylinder roller bearing inner rings can conveniently be dismantled.
A kind of instrument of dismounting NU type cylinder roller bearing inner rings of the utility model, it is by bolt, plane bearing, distending circle
Nut, interior external conical sleeve, round nut, distending tapered sleeve and dog link composition are clamped, it is characterized in that some bar grooves are provided with interior external conical sleeve,
Equipped with round nut is clamped on the external screw thread of interior external conical sleeve, hole is built with cone distending set；It is equipped with the external screw thread of distending tapered sleeve
Distending round nut, bolt is screwed with screwed hole, end face is equipped with plane bearing；Interior external conical sleeve aperture is built with dog link.
Brief description of the drawings
Fig. 1 is schematic diagram of the NU types cylinder roller bearing on axle, and outside is equipped with circlip for shaft；Fig. 2 is NU types
Cylinder roller bearing removes schematic diagram when outer ring and roller on axle, and only inner ring is enclosed on axle；
Fig. 3 is a kind of instrument schematic diagram of dismounting NU type cylinder roller bearing inner rings of the utility model
In figure：Bolt (1), plane bearing (2), distending round nut (3), interior external conical sleeve (4), clamp round nut (5), distending
Tapered sleeve (6), dog link (7)；
Fig. 4 is the sectional view of interior external conical sleeve (4) of the present utility model
In figure：Aperture (4-1), groove (4-2), back taper (4-3), inner cone (4-4), outer cone (4-5), external screw thread (4-6)；
Fig. 5 is the A direction views of interior external conical sleeve (4) of the present utility model, is uniformly distributed some bar grooves；
Embodiment
A kind of instrument of dismounting NU type cylinder roller bearing inner rings of the utility model be by bolt (1), plane bearing (2),
Distending round nut (3), interior external conical sleeve (4), clamp round nut (5), distending tapered sleeve (6), dog link (7) composition, the interior outer cone
Apply mechanically spring steel to be made, and thermally treated, it is had enough elasticity, it is cylindrical on have external screw thread and have outer cone, endoporus has inner cone,
Some bar grooves are provided with above, are equipped with the external screw thread of interior external conical sleeve and are clamped round nut, hole is built with distending tapered sleeve；The distending cone
Distending round nut is housed on the external screw thread of set, bolt is screwed with screwed hole, end face is equipped with plane bearing, interior external conical sleeve aperture
Built with dog link, distending round nut is tightened, distending tapered sleeve moves to left, and after interior external conical sleeve reverse taper holes footpath increase, is set to roller bearing
Side inside inner ring, distending round nut is unclamped, tap bolt head, move to right external conical sleeve, tighten clamping round nut, interior external conical sleeve
Back taper aperture is reduced, and tightens the end face that bolt withstands axle, cylinder roller bearing inner ring is pulled out, and holds dog link, prevents from twisting
Distending tapered sleeve rotates during tight bolt.
