Abstract

The utility model relates to a support deformation guide roller with three bearings, which comprises a guide roller body, a small guide roller shaft, seal rings and the three bearings, wherein the guide roller body is mounted on the small guide roller shaft in a sleeving manner; the bearings are fixedly mounted between the guide roller body and the small guide roller shaft; and the seal rings are mounted at the two ends of the guide roller body in an embedded manner. The support deformation guide roller is characterized in that the three bearings are all fixedly mounted in a gap between the guide roller body and the small guide roller shaft; one bearing is fixedly mounted in the middle; and the other two bearings are fixedly mounted at the two end parts. The support deformation guide roller with the three bearings is scientific and reasonable in structural design and has the advantages of large support force, high bearing capacity, firmness, durability, long service life, capability of effectively improving the production efficiency, higher innovativeness and the like.

Description

A kind of three bearings distortion deflector roll

Technical field

The utility model belongs to helix tube production equipment field, particularly a kind of three bearings distortion deflector roll.

Background technology

The supporting deformation deflector roll is the vitals on the helix tube molding machine; its effect is the rotation of support helix pipe and makes the helix tube moulding; because its load-bearing is large, stressed large; be the consumable accessory on the forming machine, the supporting deformation deflector roll that particularly in the past used is all two bearings, and structure is unreasonable; cause the supporting deformation deflector roll fragile; life-span is short, shuts down and changes frequently, has a strong impact on production.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, but provides a kind of three bearings rational in infrastructure, durable, long service life Effective Raise production efficiency to be out of shape deflector roll.

The utility model solves its technical problem and is achieved through the following technical solutions:

A kind of three bearings distortion deflector roll, comprise deflector roll body, the little axle of deflector roll, sealing ring, bearing, the deflector roll body is sleeved on the little axle of deflector roll, be fixedly mounted with bearing between the little axle of deflector roll body and deflector roll, sealing ring is flush-mounted in deflector roll body two ends, and its innovation is: described bearing is 3 groups, all is installed in the space between the little axle of deflector roll body and deflector roll, wherein one group is installed in the middle part, and two groups are installed in respectively both ends in addition.

And described sealing ring is 2, is set with on the little axle of deflector roll and is flush-mounted in deflector roll body both ends of the surface.

Advantage of the present utility model and beneficial effect are:

1. this three bearings distortion deflector roll is equipped with 3 groups of bearings, and support force is large, and holding capacity is strong, and is durable, long service life;

2. this three bearings distortion deflector roll is not fragile, and need not frequent shutdown and change, but Effective Raise production efficiency.

3. this three bearings distortion guide roller structure design science is reasonable, but has that support force is large, holding capacity is strong, an advantage such as durable, long service life Effective Raise production efficiency, has higher novelty.

Description of drawings

Fig. 1 is the structural representation of the utility model three bearings distortion deflector roll.

1-sealing ring, 2-bearing, 3-bearing, 4-deflector roll body, 5-bearing, 6-sealing ring, the little axle of 7-deflector roll.

The specific embodiment

The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.

A kind of three bearings distortion deflector roll, comprise deflector roll body 4, the little axle 7 of deflector roll, sealing ring 1,6, bearing 2,3,5, the deflector roll body is sleeved on the little axle of deflector roll, be fixedly mounted with bearing between the little axle of deflector roll body and deflector roll, sealing ring is flush-mounted in deflector roll body two ends, and described bearing is 3 groups, all is installed in the space between the little axle of deflector roll body and deflector roll, wherein one group is installed in the middle part, and two groups are installed in respectively both ends in addition.

Sealing ring is 2, is set with on the little axle of deflector roll and is flush-mounted in deflector roll body both ends of the surface.

Operation principle of the present utility model is:

This three bearings distortion deflector roll is equipped with 3 groups of bearings; overcome original two bearings supporting deformation deflector roll middle part and left the deficiency that the space causes holding capacity to descend; support force and the holding capacity of supporting deformation deflector roll have greatly been strengthened; so more durable; not fragile; long service life is changed without frequent shutdown in the production process, thus Effective Raise production efficiency.

Claims

1. a bearings is out of shape deflector roll, comprise deflector roll body, the little axle of deflector roll, sealing ring, bearing, the deflector roll body is sleeved on the little axle of deflector roll, be fixedly mounted with bearing between the little axle of deflector roll body and deflector roll, sealing ring is flush-mounted in deflector roll body two ends, it is characterized in that: described bearing is 3 groups, all is installed in the space between the little axle of deflector roll body and deflector roll, wherein one group is installed in the middle part, and two groups are installed in respectively both ends in addition.
