Abstract

The utility model relates to a taper drawing belt-roller bearing jointing part which belongs to a new technique for substituting a drawing belt-roller bearing jointing part used in the prior cotton spinning industry and overcomes the defects of the prior drawing belt-roller bearing jointing part that the whole machine is disabled after being abraded. A taper structure is used instead of the prior cylindrical structure, and a row of ball bearings is used instead of a row of needle bearings, thereby the axial positioning is solved. The utility model has the advantages that the aims of material conservation, long service life and convenient assembly can be achieved.

Description

Tapering drafting roller bearing conjunction

Affiliated technical field

The utility model is a kind of novel tapering drafting roller bearing conjunction of drafting roller bearing conjunction that substitutes the ready-made use of cotton spinning industry, and it has material-saving, long service life, universal standard structural member easy to assembly.

Background technology

At present, the drafting roller bearing conjunction that cotton spinning is already used is: the roller two ends are furnished with in the bearing holder (housing, cover) of Shuan Pai Roll needle bearing for the polishing cylinder inside of packing into, because drafting roller high-speed cruising, roller two ends polishing cylinder and Shuan Pai Roll needle bearing meeting fair wear and tear, progressively increasing along with wearing and tearing, cause the fit clearance between it to increase, finally cause drafting roller bearing conjunction integral body to be scrapped.

Summary of the invention

For overcoming the shortcoming that current drafting roller bearing conjunction wearing and tearing back integral body is scrapped, the utility model is the cone that the cylinder of roller two ends polishing is changed into polishing, inside is furnished with the bearing holder (housing, cover) of two row Roll needle bearings and makes Updatable universal standard knots member, whenever bearing wear, only need to change this universal standard structural member, keep with the many roller spares of material.

The technical scheme that the utility model adopted is: the preceding end Roll needle bearing of retaining shaft bearing sleeve, back end Roll needle bearing change to Roll pearl bearing and the tightening up close joining of roller axle of two nose cones after the axis of cone and the improvement mixing in two bearings in.

The beneficial effects of the utility model are: reach material-saving, long service life, purpose easy to assembly.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is that master of the present utility model looks the cross-section structure full figure.

Fig. 2 is the partial enlarged drawing that master of the present utility model looks cross-section structure one end.

1. end caps among the figure, 2. trip bolt, 3. compressing tablet, 4. back sealing, 5. back centring ring, 6. Roll pearl, 7. interfix circle, 8. Roll pin, 9. prelocalization circle, 10. before sealing, the axis of cone in 11., 12. bearing holder (housing, cover)s, 13. roller axles.

The specific embodiment

The inner cone of the interior axis of cone (11) will with close the joining of cone at roller axle (13) two ends, material bearing steel;

Bearing holder (housing, cover) (12) keeps last Pai Roll pin, removes back Yi Pai Roll pin, and Gai Wei Roll pearl adds the sealing of three road centring rings and front and back,

All the other apparent sizes are the same with passing through with bearing holder (housing, cover), the material bearing steel;

The interior axis of cone (11) bearing holder (housing, cover) (12) of packing into is become universal standard structural member;

Roller axle (13) two ends are designed to cone and have inner bolt hole, all the other sizes are the same with passing through with the roller axle, bearing holder (housing, cover) (12) universal standard structural member, compressing tablet (3.) are loaded onto in its two ends, and trip bolt (2), end cap (1) just become Fig. 1 sample of the present utility model.

Claims
