Abstract
The utility model relates to a kind of Weight type bearing puller, screw rod one end is welded with handle and die head, after die head, cover has block stamp, middle part spins connection lever, the other end spins expansion head, connect lever two ends by a pinned connection left side, reverse side dead man, club head is pulled out in positive and negative the forward and reverse eave tile turned up.When using the utility model, expansion head is close on inclined-plane in the dead man of positive and negative, inserts bearing inner race, be rotated counterclockwise handle, positive and negative dead man is expanded under expansion head effect, and positive and negative are pulled out the club head forward and reverse eave tile that turns up and are clamped on bearing inner race; Artificial force by weight to die head reverse slide, and then impact die head, die head drive screw rod and be screwed in connection lever on screw rod, bearing pin, positive and negative pull out club head and outwards move, the forward and reverse eave tile that club head is pulled out in positive and negative catches on bearing inner race makes bearing outwards move, and extracts bearing.The utility model structure is simple, easy to operate, laborsaving, can extract various bearing fast and to its not damaged.
Description
Technical field
The utility model relates to a kind of Weight type bearing puller.
Background technology
Bearing on equipment, has very high running accuracy requirement mostly, is to eliminate elastic deformation and vibration effect, and bearing outer ring adopts interference fit, due to outer ring may dismantle on casing very inconvenient.Weight type bearing puller, expansion head is adopted to coordinate positive and negative to pull out club head to the forward and reverse eave tile clamping bearing inner race turned up, artificial slip weight, percussion welding is connected on the die head of polished rod one end, die head drives screw rod, link lever, bearing pin, positive and negative dead man club head outwards to move, extract bearing, simple to operate, to bearing not damaged, effective.
CN203622353 discloses a kind of accelerating gear bearing puller, primarily of top, accelerating gear bearing pusher dog, gripper shoe, push rod is formed, described top is upper and lower two cylindrical integrated formed structures, and superposed cylindrical central part is provided with cone-shaped groove, the cylindrical outer diameter being positioned at bottom is less than bearing bore diameter, push rod main body is screw rod and push rod lower end is taper shape, gripper shoe is hollow cylindrical and gripper shoe inwall is provided with the screw thread matched with push rod, holddown groove is had at gripper shoe radial equipartition, holddown groove is run through in accelerating gear bearing pusher dog upper end, lower end is provided with eave tile, accelerating gear bearing pusher dog upper end is fixed on above holddown groove by nut.During use, accelerating gear bearing pusher dog upper end is fixing on the supporting plate by nut, according to the installation site of bearing outside diameter size adjustment accelerating gear bearing pusher dog, be installed to by push rod in the middle part of gripper shoe, bottom, top is placed in the middle through-hole of bearing, and eave tile is fixed on bearing lower surface, boatswain chair is pacified on push rod, spanner rotates clockwise push rod, drives accelerating gear bearing pusher dog to move up, extracted by bearing by gripper shoe.Dismounting accelerating gear bearing is become only to need 3 ~ 8 minutes.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, aims to provide a kind of structure simple, easy to operate, laborsaving, can extract various bearing fast and to its undamaged Weight type bearing puller.
The implementation of the utility model object is, Weight type bearing puller, screw rod one end is welded with handle and die head, after die head, cover has block stamp, middle part is connected with connection lever, the other end spins expansion head, and there is positive and negative dead man at described connection lever two ends by pinned connection, and the oriented forward and reverse eave tile turned up of club head is pulled out in positive and negative.
When using the utility model, inclined-plane in the dead man of positive and negative is close on expansion head, inserts bearing inner race, be rotated counterclockwise handle, positive and negative dead man is expanded under expansion head effect, and positive and negative are pulled out the club head forward and reverse eave tile that turns up and are clamped on bearing inner race; Artificial force by weight to die head reverse slide, and then impact die head, die head drive screw rod and be screwed in connection lever on screw rod, bearing pin, positive and negative pull out club head and outwards move, positive and negative are pulled out the club head forward and reverse eave tile that turns up and are caught on bearing inner race bearing is outwards moved, and extract bearing.
The utility model structure is simple, easy to operate, laborsaving, can extract various bearing fast and to its not damaged.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Referring to Fig. 1 in detail the utility model is described in detail.
With reference to Fig. 1, screw rod 7 one end is welded with handle 1 and die head 11, after die head, cover has block stamp 2, middle part is connected with and connects lever 3, the other end spins expansion 6, described connection lever 3 two ends are connected with positive and negative dead man 9,4 by bearing pin 10, and the oriented forward and reverse eave tile 8,5 turned up of club head is pulled out in positive and negative.
When using the utility model, inclined-plane in positive and negative dead man 9,4 is close in expansion 6, inserts plan and pull out bearing inner race, be rotated counterclockwise handle 1, positive and negative dead man is expanded under expansion head effect, and positive and negative are pulled out the club head forward and reverse eave tile 8,5 that turns up and are clamped on bearing inner race; Artificial force by weight 2 to die head 11 reverse slide, and then impact die head, die head drive screw rod 7 and be screwed in connection lever 3 on screw rod, bearing pin 10, positive and negative pull out club head 9,4 and outwards move, positive and negative are pulled out the club head forward and reverse eave tile 8,5 that turns up and are caught on bearing inner race bearing is outwards moved, and extract bearing.
The utility model structure is simple, easy to operate, laborsaving, can extract various bearing fast and to its not damaged.
