Abstract
The utility model discloses a bearing puller, comprising a pulling head (1) and a threaded rod (2), wherein one end of the threaded rod (2) is in threaded connection with the pulling head (1), the threaded rod (2) is provided with a connecting piece (3) in threaded connection with the threaded rod (2), and two end surfaces of the connecting piece (3) are respectively provided with a right angled triangle support (4). The bearing puller provided by the utility model has the advantages of simple structural design and convenience of use, and can help an operator to conveniently and rapidly take out a bearing so as to improve the assembly and maintenance efficiency, and meanwhile, the bearing and a product are not damaged, so that the maintenance quality is improved.
Description
Technical field
The utility model relates to a kind of assembly repair kit, particularly a kind of bearing puller.
Background technology
In the assembling maintenance, for the bearing that is arranged in the deep hole, owing to be subjected to the restriction of deep hole, brought inconvenience for the dismounting of bearing, some factories are when the dismounting bearing, adopt the simple tools such as pin of punching pin, band tapering to dismantle by force, such dismounting not only can damage bearing, but also may be with damage of product.
The utility model content
The purpose of this utility model just provides a kind of fast quick-detach bearing and does not damage the bearing puller of bearing and product.
The purpose of this utility model is to realize by such technical scheme, a kind of bearing puller, include and pull out head, it is characterized in that: described puller also comprises screw rod, one end of described screw rod is connected with the threaded one end that pulls out head, described screw rod is provided with the connector that is connected with screw flight, and the both ends of the surface of described connector are respectively arranged with the right angled triangle support.
The right-angle side of described right angled triangle support is parallel with screw rod.
Owing to adopted technique scheme, the utlity model has structural design advantage simple, easy to use, adopt its staff can conveniently take out bearing, improved the assembling maintenance efficiency, simultaneously, it can not damage bearing and product, has improved the quality of maintenance.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of bearing puller, include and pull out 1, it is characterized in that: described puller also comprises screw rod 2, one end of described screw rod 2 is connected with a threaded one end that pulls out 1, described screw rod 2 is provided with the connector 3 that is threaded with screw rod 2, and the both ends of the surface of described connector 3 are respectively arranged with right angled triangle support 4.The right-angle side of described right angled triangle support 4 is parallel with screw rod 2.
The utility model is to use like this: will pull out 1 and go deep in the inner ring of bearing, clamp with spanner and to pull out 1, rotating screw bolt 2 then, make and pull out promptly bearing of 1 an expansion back, rotating right angled triangle support 4 again rotates around screw rod 2, make right angled triangle support 4 be adjusted to proper height, pull out 1 for a rise with pneumatic impact spanner rotary screw 2 to the drive of rising at last bearing is extracted.Because screw rod 2 is designed to two sections opposite screw threads of rotation, promptly the direction of rotation of bearing is opposite with pulling out 1 for an expansion for the direction of rotation of ascent direction, can not cause in the uphill process pulling out getting loose.
Claims (2)
1. bearing puller, include and pull out head (1), it is characterized in that: described puller also comprises screw rod (2), one end of described screw rod (2) is connected with the threaded one end that pulls out head (1), described screw rod (2) is provided with the connector (3) that is threaded with screw rod (2), and the both ends of the surface of described connector (3) are respectively arranged with right angled triangle support (4).
2. bearing puller as claimed in claim 1 is characterized in that: the right-angle side of described right angled triangle support (4) is parallel with screw rod (2).
