Description

Oil seal installation tool

This creation is about an installation tool, especially an oil seal installation tool used to assist in the installation of oil seals.

In power transmissions, an oil seal is often used as a sealing element to avoid leakage of fluid (such as lubricating oil) inside the device. However, if the oil seal is not properly installed, it may cause deformation of the oil seal, damage to the shaft or oil seal, and thus affect the sealing effect of the oil seal.

In this regard, there is currently an industry developer, such as the "Oil Seal Demolition Tool" of the Republic of China New Patent Publication No. M382184, which includes an assembly kit extending at one end with an extended convex surface defining a set of holes, the assembly The kit is provided with a uniform perforation on the other side, the through hole communicating with the sleeve hole. In use, the assembly kit can be sleeved on a shaft by the sleeve hole, and then the extended convex surface is pressed against the oil seal and flattened to a proper sealing position of the shaft. In addition, the bolt can be inserted into the through hole of the assembly by a bolt, and the bolt can be screwed with the screw hole of the shaft to further advance the assembly by rotating the bolt, thereby shifting the oil seal to The proper sealing position of the shaft.

However, the assembly kit of the above tools is not convenient for tapping tools on the one hand, which affects the installation efficiency. On the other hand, if the assembly kit is used for tapping the tool, it may be deformed and affect the durability of the product. In addition, if the oil seal can be placed outside the side cover of the transmission device or the like, the oil seal can be directly replaced without removing the side cover, which can greatly save time and cost for maintenance. However, the installation tool therefore requires a corresponding configuration to enhance the ease of installation.

Therefore, in order to further improve the convenience of the oil seal installation, the present author proposes an oil seal installation tool, the shaft includes an end portion and a mounting portion, the end portion is an end extending from the shaft seat, and the mounting portion is adjacent to the end portion. And the installation section has a diameter wider than the diameter of the end portion to form a first edge. The oil seal installation tool comprises: a grip bar comprising a set of ends; and an impact member detachably mounted on the assembly The end includes a set of holes, a through hole and an abutting end, wherein the hole has a diameter substantially equal to a diameter of the mounting portion of the shaft, the through hole communicates with the set hole, and the through hole has an offset between the hole and the set hole a flange, the abutting edge corresponding to the edge of the shaft, the aperture of the perforation corresponding to the shaft for the shaft to extend, the width of the abutting end is substantially equal to or greater than the oil seal, The oil seal is moved by the abutting end.

Further, the grip comprises a tube body having a through hole, and the set of ends has an opening communicating with the through hole for the shaft to extend into the through hole.

Further, the grip bar includes a latch portion adjacent to the opening, and the impact member detachably chucks the latch portion.

Further, the latching portion is a ball, and the impacting member includes a connecting end, the connecting end is opposite to the abutting end, and the connecting end has a ring groove to allow the connecting end to extend into the opening The ball is stuck in the ring groove.

Further, the set of ends has a consistent perforation, the through hole is for the ball to be loaded and the through hole is closed by a piece.

Further, the abutting end has a contact surface corresponding to the oil seal.

Further, the contact surface is substantially a plane.

Further, the tube body has a stop slip.

Further, one of the tubes has a smaller diameter than the set of ends.

According to the above technical features, the following effects can be achieved:

1. The impact member can be coupled to the grip and the impact member can be fitted to the shaft. An external force can be applied to the grip to allow the impact member to smoothly slide the oil seal to the proper mounting position.

2. Since the force can be applied to the grip bar, the installation efficiency can be improved without damaging the impact member, and the product durability is better.

3. The impact member is detachably coupled to the grip to replace the impact members of different specifications.

4. It is convenient to disassemble and assemble by using the ring groove of the ball and the impact member.

5. The installation tool is suitable for directly installing the oil seal on the outside of the side cover of the transmission device, so that the oil seal can be directly installed without removing the side cover, which can greatly save the time and cost required for maintenance.

In combination with the above technical features, the main effects of the present oil seal installation tool will be clearly shown in the following embodiments.
