Abstract

The utility model relates to a roller bearing, composed of a pillar, a roll ball group, a liner and an alignment pin. The bottom of the pillar is inserted into the liner; the roll ball group is located between the pillar and the liner; the location of the roll ball group, the pillar and the liner are fixed by the alignment pin; the pillar axially rotates corresponding to the liner. Using it, the rotary part and a base are respectively connected with the pillar and the liner. The roller bearing has simple structure, a few working processes and convenient installing.

Description

Roller bearing

The utility model relates to a kind of pillar bearing.

Rotating machinery on the vertical shaft has bigger axial load, adopt existing pressure bearing workpiece (as vertical shaft, vertical rod etc.) must be processed with the metal (upper seat, with Bearing Installation in bearing support, the diameter of workpiece must be greater than bearing outside diameter for this reason, if vertical shaft adopts tubing, then need to add in addition the metal (upper block set in order to running in bearings, this pressure bearing complex structure commonly used, manufacturing procedure are many and waste raw material.

The purpose of this utility model is that an a kind of assembling pillar bearing will be provided, thereby overcomes existing bearing structure complexity, defective that manufacturing procedure is many.

The related pillar bearing of the utility model mainly is made of column, sleeve, ball and locating stud, insert in the sleeve lower end of column, one group of ball of assembling between column and the corresponding end face of sleeve, relative position between column and sleeve is fixed with locating stud, and column just can be done axial rotation with respect to sleeve by ball like this.

The utility model as long as workpiece is fixed with column and sleeve respectively, can be realized the purpose of rotation, and not need other manufacturing procedure and build-up member in use owing to adopt column, ball and the sleeve integral structure of assembling.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described further.

Fig. 1 is the general assembly structural drawing according to the pillar bearing that the utility model proposes.

Fig. 2 is the parts explosion of pillar bearing shown in Figure 1.

As Fig. 1 and Fig. 2 and shown in, the pillar bearing is made of column 1, sleeve 2, ball set 3 and locating stud 4.Column 1 comprises cylinder 11, upper-end surface 12, lower prop 13 and locating slot 14, and upper-end surface 12 is between last cylinder 11 and lower prop 13, and the diameter of upper-end surface 12 is greater than the diameter of lower prop 13, and locating slot 14 is positioned at the lower end of lower prop.Sleeve 2 comprises cylindrical shell 21 that has pin-and-hole 23 and the lower end surface 22 that is positioned at cylindrical shell 21 tops, in addition, is respectively equipped with the

ball grooves

15 and 25 of arcuation on upper-end surface 12 and lower end surface 22, and polish on the surface of groove.Ball set 3 evenly distributed one group of ball 31 on ball rack 32 forms.

Total assembling structure of this bearing as shown in Figure 1, ball set 3 is placed in the ball grooves 25 on the lower end surface 22, the lower prop 13 of column 1 inserts in the sleeve 2 and has just touched ball set 3 until upper-end surface 12, then locating stud 4 is inserted from pin-and-hole 23, locating stud just in time is arranged in locating slot 14, locating stud 4 just gets off the fixed-site between column 1, ball set 3 and the sleeve 2 like this, because polish on the surface of ball 31 and upper and

lower end face

12 and 22, friction ractor between them is very little, thereby friction is very little when column 1 is done axially rotation with respect to sleeve 2.

If certain workpiece is linked to each other with column 1, and sleeve 2 links to each other with base, and this workpiece just can be done axial rotation with respect to base so.

Claims

1, a kind of pillar bearing.It is characterized in that comprising column 1, sleeve 2, ball set 3 and locating stud 4, column 1 is made of last cylinder 11, lower prop 13 and the upper-end surface 12 between last cylinder 11 and lower prop 13, sleeve 2 is made of cylindrical shell 21 and the lower end surface 22 that is positioned on the cylindrical shell 21, the lower prop 13 of column 1 inserts in the sleeve 2, ball set 3 is between the lower end surface 22 on upper-end surface on the column 1 12 and the sleeve 2, and locating stud 4 inserts in the locating slot 14 of lower prop 13 lower ends that are located at column 1.

2,, it is characterized in that being respectively equipped with ball grooves 15 and 25 on described upper-end surface 12 and the lower end surface 22 according to the pillar bearing of claim 1.
