Section 224 is provided and is contacted with bearing 3, and provides the supporting surface 224a of support to bearing 3, and above-mentioned groove 201 provides contact surface 201a,
But when contact surface 201a is inclined-plane, contact surface 201a does not ensure that 3 position of bearing is completely firm, thus support shaft
22 supporting surface 224a and contact surface 201a, which cooperates, can guarantee that 3 position of bearing does not glide, i.e., position is fixed.
And support shaft 22 further includes pressure-bearing section 225；225 one end of pressure-bearing section is abutted against with supporting section 224, the other end and pressure
Lid 23 is flexibly connected.Namely support shaft 22 includes pressure-bearing section 225, supporting section 224 and positioning section 221, top from top to bottom
Pressure-bearing section 225 be flexibly connected with gland 23, contact above-mentioned statement it is found that gland 23 is covered on the top of pressure-bearing section 225.
As shown in figure 5, gland 23 includes the step surface 231 for applying pressing force to bearing 3；It is understood that grease exists
There is pressure under the supply of grease supply unit 1, under such pressure, it is unstable that bearing 3 is likely to position, thus gland 23
Pressing force is applied to bearing 3, so that 3 position of bearing is fixed, such bearing 3 is located in contact surface 201a, supporting surface 224a and platform
Between terrace 231, bearing can position fix.
Gland 23 it is opposite with supporting surface 224a offer blind hole 232 on one side；The other end of pressure-bearing section 225 is installed in blind hole
In 232.Gland 23 is covered on the top of pressure-bearing section 225, and the mode directly covered makes connection and unstable, holds in the application
Pressure section 225 is located in blind hole 232, and in this way under the action of pressing force, the position of gland 23 and pressure-bearing section 225 is fixed.
Greasing unit 2 further includes clamp 25；Clamp 25 is connected with gland 23, and can be by gland 23 along the axis of support shaft 22
It is promoted or is reduced.Gland 23 is covered on pressure-bearing section 225, when installing bearing 3, needs to lift on gland 23, and 23 weight of gland
It measures heavier, only is not easy to realize by manpower operation, thus be connected with gland 23 using clamp 25, when operation, it is only necessary to is manual to grasp
Making clamp 25 can be by 23 pull-up of gland, and when needing to compress gland 23, manual compression clamp 25 be can be realized, and operates in this way
Simplicity, saving manpower, and whole device are simultaneously uncomplicated, are easy to dismount and repair.
Grease supply unit 1 in the embodiment of the present application includes:
Depot fat tank 11；
