Description

Bottom plate of gearbox filter

Technical Field

The utility model relates to a gearbox filter accessory, in particular to a bottom plate of a gearbox filter.

Background

A transmission filter is a device which is arranged in a transmission and has a filtering function. The lubricating liquid in the gearbox flows in the gearbox, and when parts are lubricated, impurities attached to the surfaces of the parts in the gearbox can be washed down, the washed impurities can be filtered when the lubricating liquid flows through a gearbox filter, and the filtered clean lubricating liquid can enter the gearbox again for circulation.

The shell of the existing gearbox filter is generally designed to be split and is assembled by matching a bottom plate and an upper cover. The bottom plate is provided with an outlet of lubricating liquid, the outlet is connected with the gearbox, and the filtered lubricating liquid returns to the inside of the gearbox again. In order to avoid leakage of the lubricating fluid, a seal between the outlet and the gearbox is therefore important, usually by providing a sealing ring. The sealing ring is arranged at the outlet through the matching of the elasticity of the sealing ring and the annular groove formed at the outlet, and the sealing ring can deform after being used for a long time, so that the sealing ring is loosened from the outlet, and the sealing is ineffective.

Disclosure of Invention

Aiming at the problems in the prior art, the utility model provides the bottom plate of the gearbox filter, so that the installation of a sealing ring is firmer and more reliable.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a bottom plate of gearbox filter, includes the body, be equipped with the filtration mouth on the body, filtration mouth department is equipped with the sealing washer, the filtration mouth corresponds the sealing washer and is equipped with rather than complex annular, be equipped with the rand of two relative settings on two inside lateral walls of annular, the rand encircles the circumference setting of annular, the position that corresponds the rand on the sealing washer be equipped with can with the recess of rand block.

By adopting the technical scheme, the sealing ring is clamped in the annular groove by the clamping of the two clamping rings and the upper groove of the sealing ring, and the sealing ring is extruded by the annular groove to generate elastic force, so that the sealing ring is more firmly installed, and the sealing ring can be fixed in the annular groove due to the clamping rings after the sealing ring deforms, thereby avoiding the loosening of the sealing ring.

Furthermore, the other side of the sealing ring opposite to the side matched with the ring groove is provided with a single raised arc surface.

By adopting the technical scheme, the sealing ring is sealed by the rebound force generated by the deformation of the compressed arc surface, and the arc surface is the sealing surface.

Furthermore, the other side of the sealing ring, which is opposite to the side matched with the ring groove, is provided with a plurality of raised arc surfaces, and the arc surfaces are parallel to each other and are arranged into a wave shape.

By adopting the technical scheme, the sealing ring is provided with a plurality of sealing surfaces, when one of the sealing surfaces goes wrong, other sealing surfaces are used for sealing the sealing ring, and the leakage of the sealing ring is avoided.

Furthermore, the filter opening is also provided with a mounting piece for connecting the filter opening with the gearbox.

Adopt above-mentioned technical scheme, set up like this and make the filtration mouth be connected through the cooperation of installed part with the gearbox to the installation of filtration mouth and gearbox.

Further, the mounting piece is a thread formed on the filter opening.

By adopting the technical scheme, the filtering port and the gearbox are connected through thread fit by the arrangement, so that the filtering port and the gearbox are convenient to detach and install.

Further, the installed part is a plurality of jack catch, and the jack catch sets up along the circumference equidistance of filtration mouth.

Adopt above-mentioned technical scheme, set up like this and utilize the cooperation between a plurality of jack catchs the gearbox part that meets with the filtration mouth and holds with the jack catch and hold fixedly to make filtration mouth and gearbox fixed connection, make the fixed of filtration mouth and gearbox firm, reliable more.

Figure 4 shows one arrangement of the mounting members.

Figure 5 shows an alternative arrangement of the mounting member.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples.

As shown in fig. 1 a bottom plate of gearbox filter, which comprises a body 1, be equipped with filtration mouth 2 on the body 1, filtration mouth 2 department is equipped with sealing washer 3, filtration mouth 2 corresponds sealing washer 3 and is equipped with rather than complex annular 4, be equipped with the rand 5 of two relative settings on two inside lateral walls of annular 4, rand 5 encircles the circumference setting of annular 4, the position that corresponds rand 5 on the sealing washer 3 is equipped with can with the recess 6 of rand 5 block. Through the block of two rand 5 and sealing washer 3 upper groove 6, block sealing washer 3 in annular 4, in addition sealing washer 3 self receives the annular 4 extrusion and the elasticity that produces, makes the installation of sealing washer 3 more firm, because rand 5's existence after sealing washer 3 warp, can fix sealing washer 3 in annular 4 to avoid the pine of sealing washer 3 to take off.

The cross section of the collar 5 may be circular arc, rectangular, wedge-shaped, etc., and in this embodiment, the cross section is circular arc.

The sealing ring 3 has two different arrangement modes:

as shown in fig. 2, the other side of the sealing ring 3 opposite to the side matched with the ring groove 4 is provided with a single convex arc surface 7. The arrangement is that the sealing ring 3 realizes sealing by the rebound force generated by the deformation of the compressed arc surface 7, and the arc surface 7 is a sealing surface.

As shown in fig. 3, the sealing ring 3 is provided with a plurality of convex arc surfaces 7 on the other side of the side matched with the ring groove 4, and the arc surfaces 7 are parallel to each other and arranged in a wave shape. The arrangement enables the sealing ring 3 to be provided with a plurality of sealing surfaces, when one of the sealing surfaces is in trouble, the other sealing surfaces are used for realizing the sealing of the sealing ring 3, and the leakage of the sealing ring 3 is avoided.

And a mounting part 8 for connecting the filtering port 2 with a gearbox is also arranged at the filtering port 2. The mounting 8 has two different arrangements:

as shown in fig. 4, the mounting member 8 is a screw thread formed on the filter port 2. Set up like this and make to be connected through screw-thread fit between filtration mouth 2 and the gearbox for filtration mouth 2 and gearbox convenient to detach and installation.

As shown in fig. 5, the mounting member 8 is a plurality of jaws, and the jaws are arranged at equal intervals along the circumference of the filter opening 2. The cooperation between a plurality of jack catchs is utilized in the setting like this, will grab fixedly with jack catch with the gearbox part that filter 2 meets to make filter 2 and gearbox fixed connection, make filter 2 more firm, reliable with the fixed of gearbox.
