Abstract

The present invention relates to a kind of machinery field, more particularly to a kind of sealing ring press-in device.According to technical solution provided by the invention, the sealing ring press-in device, including main body and press-in axis, it is pressed into the upper end of axis and bottom and is respectively less than the middle part for being pressed into axis, step is respectively formed between the upper end and middle part of press-in axis and between middle part and bottom, the middle part for being pressed into axis is in back taper, and be connected main body outside the middle part of press-in axis, and the main body is also tapered.Prevent the unnecessary rubber of sealing ring from being moved to sealing groove mouth while indentation sealing circle, during the bidirectional-movement of main body, ensure sealing ring whole indentation sealing groove, avoid occurring not being pressed onto position, flange, trimming phenomenon, ensure bearing seal performance and bearing service life.

Description

Sealing ring press-in device
Technical field
The present invention relates to a kind of machinery field, more particularly to a kind of sealing ring press-in device.
Background technology
Sealing bearing is usually that sealing ring is pressed into bearing seal groove to prevent the grease of Bearing inner from overflowing, sealing ring pressure After entering bearing seal groove, outer lip and the bearing outer ring seal groove of sealing ring are fitted close, and must not have relative motion；Sealing ring Inner lip and seal groove cooperation are more loose, can there is relative motion.Since sealing ring material is generally rubber parts, plus the sealing of bearing Groove is shaped by turnery processing, and sealing ring surface roughness value is higher, and size and dimension also not necessarily complies fully with drawing It is required that along with the deformation of heat treatment lasso, so after sealing ring outer lip is pressed into bearing outer ring seal groove, sealing ring outer lip Opening is difficult preferably to be fitted close with outer ring seal groove.For sealing ring to ensure the compactness coordinated with seal groove, use is larger Interference come prevent sealing ring outer ring seal groove produce relative motion, prevent sealing ring from coming off, but coordinate tension, unnecessary rubber Seal groove is easily routed up, flange is formed, influences appearance, at present conventional sealing ring press-in device, otherwise pressure is not in place or produces Excision is introduced into the rubber of seal groove, and trimming phenomenon, the final service life for influencing bearing occurs.
The content of the invention
Present invention aims at sealing ring press-in device is provided, seal groove is introduced into avoid not in place or generation excision is pressed Rubber the problems such as.
According to technical solution provided by the invention, the sealing ring press-in device, including main body and press-in axis, it is pressed into axis Upper end is respectively less than the middle part for being pressed into axis with bottom, equal shape between the upper end and middle part of press-in axis and between middle part and bottom Into step, the middle part for being pressed into axis is in back taper, and be connected main body outside the middle part of press-in axis, and the main body is also tapered.
There is the horn-like body outwards tilted down in the lower end outer rim of main body；The outer rim of lower end in the middle part of press-in axis has pre- Pressed-in block, the outer surface of the pre- pressed-in block are the round table surface outwards tilted down；The horn-like body is located at pre- pressed-in block Outside round table surface.
For the present invention using a kind of high resiliency, the special nylon material of high intensity as press-in main body, body interior is in back taper Design, the press-in axis coordinated with main body is tapered, and press-in axis is metal material, and main body makes master in axis axial direction operational process is pressed into Body produces journal axle bidirectional-movement, and main body is resetted using the high resiliency of material, and main body contacts press-in position with sealing ring into loudspeaker Shape, indentation sealing circle while, prevent the unnecessary rubber of sealing ring from being moved to sealing groove mouth, in the bidirectional-movement process of main body In, ensure sealing ring whole indentation sealing groove, avoid occurring not being pressed onto position, flange, trimming phenomenon, ensure bearing seal performance with Bearing service life.
The sealing ring press-in device of the present invention, is once completed the press-in and shaping of bearing sealed ring, with prior art phase Than improving production efficiency, product quality is improved.
Brief description of the drawings
Fig. 1 is the cross-sectional view of the present invention.
Embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
As shown in Fig. 1, the sealing ring press-in device includes main body 1 and press-in axis 2, is pressed into the upper end and bottom of axis 2 The middle part of axis 2 is respectively less than pressed into, step is respectively formed between the upper end and middle part of press-in axis 2 and between middle part and bottom, is pressed into The middle part of axis 2 is in back taper, the mating connection main body 1 outside the middle part of press-in axis 2, and the main body 1 is also tapered.
There is the horn-like body 3 outwards tilted down in the lower end outer rim of main body 1；Outer rim in the lower end at 2 middle part of press-in axis There is pre- pressed-in block 4, the outer surface of the pre- pressed-in block 4 is the round table surface outwards tilted down；The horn-like body 3 is located at precompressed Outside the round table surface for entering block 4.
Sealing ring press-in device of the present invention is using a kind of high resiliency, the special nylon material of high intensity as press-in main body 1, master Internal portion is designed in back taper, and the press-in axis 2 coordinated with main body is tapered, and press-in axis is metal material, and main body is in press-in axis axis Main body is set to produce journal axle bidirectional-movement into operational process, after pressing careful seal, main body is resetted using the high resiliency of material, Main body contacts press-in position with sealing ring into horn-like body 3, and indentation sealing circle while prevents the unnecessary rubber of sealing ring to close Sealing groove mouth move, during the bidirectional-movement of main body, ensure sealing ring whole indentation sealing groove, avoid occur be not pressed onto position, Flange, trimming phenomenon, ensure bearing seal performance and bearing service life, press-in axis 2 and bearing plane positioning step and precompressed Enter block 4 using being interference fitted, prevent that main body bullet from becoming the pop-up phenomenon of process, while play the role of pre- pressure seal ring, be pressed into axis The heart is looked in head with brearing bore using taper automatic positioning.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
