Abstract
The utility model relates to an installation frock that bearing bush is sealed, the hole of characterized by installation frock adopts clearance fit with the motor shaft of installing bearing bush sealing device, and the shell of installation frock is a frustum type pillow block, frustum type pillow block includes main aspects and tip, and the external diameter of its middle and tip is less than sealing device lip internal diameter size, and the external diameter of main aspects is greater than sealing device installation motor pillow block. The reverse installation problem of sealing device lip can be solved to this frock.
Description
Technical Field
The utility model relates to a sealing device's mounting tool, in particular to sealing device's mounting tool of axle bush lubricating oil of motor.
Background
The existing bearing bush seal is that a seal lip is sleeved on a motor shaft along the shaft direction, the installation method is simple, special installation tools are not needed, the sealing device can prevent external water, dust and the like from entering the inside of the bearing bush after installation, but can not prevent lubricating oil inside the bearing bush from leaking to the outside of the bearing bush, and particularly after certain pressure exists inside the bearing bush, the lubricating oil of the bearing bush is more easily leaked to the outside of the bearing bush from the contact part of the seal lip and the motor shaft. The main reason is that the internal pressure of the bearing bush can act on the sealing lip to enable the sealing lip to be in an open state, and oil leakage from the contact position between the sealing lip and the motor shaft is caused.
The sealing lip faces towards the inner side of the bearing bush is a scheme for solving the problems, but the traditional mounting method for sleeving the sealing lip on the motor shaft along the shaft direction is not suitable due to the fact that the sealing lip needs to be in interference fit with the motor shaft and the structural requirement that the sealing lip faces towards the inner side of the bearing bush is guaranteed.
Disclosure of Invention
The utility model aims at overcoming the shortcoming of background art, providing a simple structure, the frock of sealed lip can reverse installation.
The technical scheme of the utility model is that: the bearing bush seal mounting tool is characterized in that an inner hole of the mounting tool is in clearance fit with a motor shaft of a mounting bearing bush seal device, a shell of the mounting tool is a frustum-shaped boss, the frustum-shaped boss comprises a large end and a small end, the outer diameter of the small end is smaller than the inner diameter of a lip of the seal device, and the outer diameter of the large end is larger than the outer diameter of the mounting motor boss of the seal device.
The utility model has the advantages that: when the bearing bush seal is installed, the installation tool is sleeved on the motor shaft, the bearing bush seal is slowly and gradually pushed towards the outer diameter large end from the outer diameter small end of the installation tool until the bearing bush seal reaches the installation pillow block of the bearing bush seal after passing through the outer diameter large end of the installation tool. The reverse installation problem of sealing device lip can be solved to this frock.
Drawings
Fig. 1 is a structural diagram of the installation tool of the present invention;
FIG. 2 is a schematic view of the present invention during installation of the bearing bush seal;
wherein: 1. the installation tool comprises a mounting tool 2, a small end 3, a big end 4, a motor shaft 5 and a bearing bush seal.
Detailed Description
The installation tool (1) is designed and manufactured according to the size of the motor shaft diameter as shown in figure 1. The inner hole of the installation tool is in clearance fit with a motor shaft of the installation bearing bush sealing device, the shell of the installation tool is a frustum-shaped shaft platform, the frustum-shaped shaft platform comprises a large end (3) and a small end (2), and the inclination between the large end and the small end is 2 degrees. The outer diameter of the small end is 5mm smaller than the inner diameter of the lip of the sealing device, and the outer diameter of the large end is 0.5mm larger than the motor shaft platform installed on the sealing device.
As shown in fig. 2, in the first step, the mounting tool (1) is sleeved on a boss of a motor shaft (4) of the motor, on which a bearing bush seal (5) needs to be mounted. And secondly, sleeving the bearing bush seal (5) from the small end (2) of the mounting tool (1), and uniformly and slowly pushing the bearing bush seal (5) to the large end (3) of the outer diameter until the bearing bush seal passes through the large end of the mounting tool and then is sleeved on a boss of a motor shaft on which the bearing bush seal is mounted. And thirdly, taking down the installation tool (1) to complete the whole installation process.
Claims (3)
1. The bearing bush seal mounting tool is characterized in that an inner hole of the mounting tool is in clearance fit with a motor shaft of a mounting bearing bush seal device, a shell of the mounting tool is a frustum-shaped boss, the frustum-shaped boss comprises a large end and a small end, the outer diameter of the small end is smaller than the inner diameter of a lip of the seal device, and the outer diameter of the large end is larger than the outer diameter of the mounting motor boss of the seal device.
2. A bearing shell seal mounting tooling according to claim 1, wherein the taper between the large end and the small end is 2 degrees.
3. The tool for installing the bearing bush seal as claimed in claim 1, wherein the outer diameter of the small end is 5mm smaller than the inner diameter of the lip of the sealing device, and the outer diameter of the large end is 0.5mm larger than the motor boss installed on the sealing device.
