Abstract

The utility model provides a sealing push ring component serving as an important element of a build-in distributor component of a bearing support, and is mounted in front and behind the build-in distributor. The sealing push ring component comprises a sleeve, an O-shaped ring and a sealing push ring, wherein, the sleeve adopts a carbon-steel seamless steel pipe 20; a step with a certain depth is processed at the end part of the sleeve; the length of the sleeve is subject to the structure of a bearing support; the O-shaped ring is made of rubber, and can be made into different models according to actual requirements; the sealing push ring is made of nylon; two grooves in which the O-shaped ring is mounted are formed at the head of the sealing push ring; the two grooves adopt a preparation groove and a working groove; and the inner hole of the sealing push ring is processed into a threaded structure, so as to facilitate installation and disassembly. When the sealing push ring component is mounted, the O-shaped ring is pushed from the preparation groove to the working groove, and the O-shaped ring is extruded and deformed due to the extrusion effect between the sealing push ring and the sleeve, so that the O-shaped ring is in close fit with the mounting hole of the build-in distributor component of the bearing support to realize favorable sealing effect.

Description

Sealing throw-out collar assembly

Technical field

The utility model relates to the oil gas lubricating system of many friction pairs work-roll chock, uses good oil gas distribution technique and sealing technique, presses the oil and gas content of each lubricating point of the accurate distribution shaft bearing of actual demand.

Background technique

For the oil-air lubrication of many friction pairs work-roll chock, adopt the built-in dispenser assembly of bearing support to carry out oil gas mostly and distribute, the oil gas sendout of each lubricating point is controlled by oil and gas distributor.At present, the built-in dispenser assembly of most of bearing supports is simply to be in series by built-in distributor and sleeve pipe, and owing to be Spielpassung between the hole of built-in dispenser assembly of bearing support and bearing support processing, as not taking seal approach, very easily cause the oil gas channelling, make the oil and gas content distribution of each lubricating point unbalance, to the safe operation generation adverse influence of bearing.

The model utility content

In order to overcome the built-in dispenser assembly assembling of existing bearing seat back this deficiency of poor sealing, the utility model provides a kind of sealing throw-out collar assembly, sealing throw-out collar assembly is installed on before and after the built-in distributor, can play good sealing effect, has avoided the oil gas crossfire between each lubricating point.

The technological scheme that the utility model adopted is:

A kind of sealing throw-out collar assembly comprises sleeve pipe, O type circle, sealing throw-out collar, and it is characterized in that: O type circle is positioned on the sealing throw-out collar, utilizes sealing throw-out collar and sleeve pipe with the extrusion-deformation of O type circle.

As further improvement, the material of wherein said sleeve pipe is a carbon steel seamless steel pipe 20, is provided with stair-stepping hole in the end, is beneficial to and seals throw-out collar and cooperate.

As further improvement, wherein said sealing throw-out collar material is a nylon, and groove in place and the work nest that O type circle is installed arranged in head design, before installing, O type circle is positioned at groove in place, after installation, because the squeezing action between sealing throw-out collar and the sleeve pipe, O type circle are pushed toward work nest; The indoor design of sealing throw-out collar has worm structure, is convenient to dismounting.

The beneficial effects of the utility model are as follows:

Sealing throw-out collar modular construction is simple, be convenient to install, after will sealing the throw-out collar assembly and being installed in the built-in dispenser assembly mounting hole of bearing support, can avoid between the adjacent oil and gas distributor guaranteeing all to flow to the lubricating point of appointment through the rationed oil gas of oil and gas distributor because of sealing the bad oil gas crossfire that produces.

Embodiment

As shown in Figure 1, as the important component part of the built-in dispenser assembly of bearing support, each element is in series sealing throw-out collar assembly (comprising 6,7,8), and the active force that produces by locking nut 3 compresses sealing throw-out collar assembly mutually, produces sealing effect.

The material of sleeve pipe 4 (referring to Fig. 2) is a carbon steel seamless steel pipe 20, and length is according to the structure customization of bearing support.Inside pipe casing is processed as the ladder of certain depth, can better and seal the cooperation of throw-out collar head like this O type circle is compressed.

O type circle 5 materials are rubber, select different model according to actual needs.

Sealing throw-out collar 6 (referring to Fig. 3) material is a nylon, and head is provided with groove in place 8 and the work nest 9 that O type circle 5 is installed, and groove in place is in order to prevent that O type circle comes off when mounting and dismounting, and after installation compressed, O type circle was pushed toward work nest from groove in place; Be designed to worm structure in sealing throw-out collar inside, so conveniently carry out dismounting by supporting screw thread feeler lever.

When sleeve pipe 4, O type circle 5 and sealing throw-out collar 6 malcompressions (as shown in Figure 4), O type circle is positioned at sealing throw-out collar groove in place.

Compress back (as shown in Figure 5) at sleeve pipe 4, O type circle 5, sealing throw-out collar 6, O type circle is pushed toward work nest, because the squeezing action between sealing throw-out collar and the sleeve pipe, O type circle is extruded distortion, closely cooperate with the built-in dispenser assembly mounting hole of bearing support, play good sealing effect.

Claims

1. a sealing throw-out collar assembly comprises sleeve pipe, O type circle, sealing throw-out collar, and it is characterized in that: O type circle is positioned on the sealing throw-out collar, utilizes sealing throw-out collar and sleeve pipe with the extrusion-deformation of O type circle.

2. sealing throw-out collar assembly according to claim 1 is characterized in that: the material of described sleeve pipe is a carbon steel seamless steel pipe 20, is provided with stair-stepping hole in the end, is beneficial to and seals throw-out collar and cooperate.

3. sealing throw-out collar assembly according to claim 1, it is characterized in that: described sealing throw-out collar material is a nylon, be provided with groove in place and the work nest that O type circle is installed at head, before installing, O type circle is positioned at groove in place, after installation, because the squeezing action between sealing throw-out collar and the sleeve pipe, O type circle is pushed toward work nest; Sealing throw-out collar inside is provided with worm structure.
