Description

Structure of laboratory kneading machine seal shaft sleeve

Technical Field

The utility model relates to a sealed axle sleeve technical field especially relates to a structure of laboratory kneading machine sealed axle sleeve.

Background

The axle sleeve is used for replacing a rolling bearing (actually, the axle sleeve is a sliding bearing) at a place (such as a camshaft) with low rotating speed, high radial load and high clearance requirement, the hardness required by materials is low and wear-resistant, an inner hole of the axle sleeve can reach high matching precision through grinding and scraping, the sealing effect to a certain degree is realized, but relative friction can occur between the axle sleeve and the axle, and friction debris is generated.

Traditional axle sleeve simple structure, the friction piece that produces with the pivot directly flows out, and the piece can enter into raw and other materials, produces the pollution to raw and other materials.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a sealing shaft sleeve structure of a kneading machine in a laboratory.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a structure of laboratory kneading machine seal shaft sleeve, includes the seal shaft sleeve body, the side fixedly connected with of seal shaft sleeve body gathers the tetrafluoro barrier ring, gather the right flank of tetrafluoro barrier ring and set up flutedly near the outside of seal shaft sleeve body, the side of seal shaft sleeve body just is located the right side fixedly connected with sealing washer of gathering the tetrafluoro barrier ring, it is provided with annular clearance groove to gather between tetrafluoro barrier ring and the sealing washer.

As a further description of the above technical solution:

the sealing ring is made of asbestos sealing material.

As a further description of the above technical solution:

and oil storage tanks are arranged on the inner side surfaces of the polytetrafluoroethylene barrier ring and the sealing ring.

As a further description of the above technical solution:

the shape of the groove is circular ring.

The utility model discloses following beneficial effect has:

1. compared with the prior art, this structure of kneading machine seal shaft cover in laboratory through setting up recess storage structure to and the blocking of polytetrafluoroethylene barrier ring, make the piece that the relative friction of pivot and seal shaft cover produced, hardly enter into the sample, realize the protection to the sample.

2. Compared with the prior art, the structure of the sealing shaft sleeve of the kneading machine in the laboratory has the advantages that the structural design is simpler, the traditional shaft sleeve sealing is replaced, and the cost of equipment can be reduced.

Drawings

FIG. 1 is a cross-sectional view of the sealing shaft sleeve structure of a kneading machine in a laboratory;

FIG. 2 is a side view of the sealing sleeve structure of the kneader in the laboratory according to the present invention.

Illustration of the drawings:

1. a seal shaft sleeve body; 2. polytetrafluoroethylene barrier rings; 3. a groove; 4. a seal ring; 5. an annular clearance groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, and furthermore, unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-2, the utility model provides a pair of laboratory kneader sealed axle sleeve's structure: including sealed axle sleeve body 1, the side fixedly connected with of sealed axle sleeve body 1 gathers tetrafluoro and hinders spacer ring 2, gather tetrafluoro and hinder 2 right flank and be close to sealed axle sleeve body 1's the outside and seted up recess 3, be used for saving friction piece, as long as the clearance is overhauld to regular, can avoid friction piece to enter into raw and other materials, sealed axle sleeve body 1's side just is located the right side fixedly connected with sealing washer 4 that gathers tetrafluoro and hinders spacer ring 2, it is provided with annular clearance groove 5 to gather tetrafluoro and hinder between ring 2 and the sealing washer 4, make things convenient for the clastic flow of friction.

The sealing ring 4 is made of asbestos sealing materials, the sealing performance of the sealing ring and the rotating shaft is improved, oil storage grooves are formed in the inner side surfaces of the polytetrafluoroethylene spacing ring 2 and the sealing ring 4 and used for storing lubricating oil and reducing friction scraps, and the groove 3 is annular.

The working principle is as follows: during the use, the pivot cooperates with the inboard high cooperation progress of gathering tetrafluoro spacer ring 2 and sealing washer 4, realizes sealed purpose, can produce the friction with the inboard of gathering tetrafluoro spacer ring 2 and sealing washer 4 during the pivot rotates, produces the friction piece, and the friction piece can be through falling into the inside of annular clearance groove 5 and recess 3.
