Abstract
The utility model provides a kind of chuck.It comprises disk body, parcel, claw, pulls wheel, is provided with the claw groove in the disk body, is provided with the structure that reduces both frictional force between claw and claw groove opposite face.The structure of the described power of reducing friction can adopt multiple structure, such as adopting rolling element or adopting coating that lubrication is arranged or the material layer that is located on claw and the claw groove opposite face.It is rolling friction that the utility model makes the two sides of claw and disk body, and frictional force is little, and operation easily, conveniently.
Description
Technical field
The utility model relates to a kind of chuck.
Background technology
In the prior art, scroll chuck is when clamping, and claw contacts with two sides with the claw groove, and face and face are sliding frictions, and in clamping and release process, frictional force is quite big between claw and the claw groove, the operation effort.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of chuck that overcomes above-mentioned defective.For this reason, the utility model by the following technical solutions: it comprises disk body, parcel, claw, pulls wheel, is provided with the claw groove in the disk body, is provided with the structure that reduces both frictional force between claw and claw groove opposite face.
The structure of the described power of reducing friction can adopt multiple structure, such as adopting rolling element or adopting coating that lubrication is arranged or the material layer that is located on claw and the claw groove opposite face.
Owing to adopted technique scheme, the two sides of claw and disk body are rolling friction, and frictional force is little, and operation easily, conveniently.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the partial enlarged drawing on Fig. 1.
The specific embodiment
With reference to accompanying drawing.The utility model comprises disk body 2, parcel, claw 1, pulls wheel, is provided with claw groove 5 in the disk body, is provided with the structure that reduces both frictional force between claw and claw groove opposite face.
The structure of the described power of reducing friction can adopt multiple structure, such as adopting rolling element.
Described rolling element is a needle roller 3, and the claw groove is provided with the needle roller groove 4 that needle roller is set, and has assembled disk body, needle roller 3 is put into needle roller groove 4 after, again claw 1 is loaded onto.Like this, the two sides of claw and disk body are rolling friction.Certainly, described rolling element also can adopt ball.
