Embodiment Construction

[0013] The technical solution of the present invention will be described in further non-limiting detail below in combination with preferred embodiments and accompanying drawings.

[0014] Such as figure 1 As shown, the oil seal press-in mechanism with guide function corresponding to a preferred embodiment of the present invention is used to install the oil seal 1 into the installation hole 4 formed by the oil seal sleeve 2 and the gear 3, which includes a press-in head 5 and The inner guide block 7 and the outer guide block 6 . The press-in head 5 is used to press the oil seal 1 into the installation hole 4, and it is movably connected with the inner guide block 7, which includes a guide cylinder 5a and an extrusion part 5b coaxially arranged with the guide cylinder 5a. The pressure portion 5b is in contact with the end surface of the oil seal 1 for squeezing the oil seal 1 . The press-in head 5 is also provided with an inner guide hole 5c matched with the inner guide block ...

Abstract

The invention discloses an oil seal pressing-in mechanism with a guide function, used for installing an oil seal (1) in a mounting hole (4) formed between an oil seal sleeve (2) and a gear (3); an inner hole (3a) is formed in the gear (3). The oil seal pressing-in mechanism with the guide function comprises a pressing-in head (5) and an internal guide block (7) which is movably connected with thepressing-in head (5); the internal guide block (7) is provided with a projection (7a) which is matched with the inner hole (3a); the pressing-in head (5) is provided with an extrusion part (5b) used for extruding the oil seal (1); the diameter of the internal guide block (7) is a little smaller than the inside diameter of the oil seal (1); the oil seal (1) can be arranged on the internal guide block (7) in a sleeving manner. For the oil seal pressing-in mechanism provided by the invention, through design of the internal guide block (7), the oil seal (1) can be stably installed in the mountinghole (4) without the phenomena of slanting and the like, and thus the sealing performance is improved.

Description

technical field [0001] The invention relates to an oil seal pressing mechanism with guiding function. Background technique [0002] The oil seal is a mechanical element used to seal grease (oil is the most common liquid substance in the transmission system, and also generally refers to the general liquid substance). Oil leaks. It is widely used in industry, and the oil seal is prone to tilt during installation, resulting in poor sealing effect and even directly leading to the scrapping of the oil seal. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned defects in the prior art, and provide an oil seal press-in mechanism with a guiding function, so that the oil seal will not be inclined during installation. [0004] In order to achieve the purpose of the above invention, the present invention adopts the following technical solution: an oil seal press-in mechanism with guiding function, which is used to install the oil se...
