Abstract
The utility model discloses a velocity measurement roller for producing a stainless steel band with a bright surface. Each shaft end of the velocity measurement roller is in interference fit with the inner circle of a spherical roller bearing, and a bearing seat is arranged outside each spherical roller bearing. The spherical roller bearings are arranged at two shaft ends of the velocity speed roller, can bear a large radial load and meanwhile can bear a certain axial load, an outer circle roller path of the velocity measurement roller is of a spherical shape, and therefore the velocity measurement roller for producing the stainless steel band with the bright surface has centering performance, the bearing still works when a shaft is stressed to be bent or inclined to enable relative inclination of an inner circle center line and an outer circle center line not to exceed 1 degree to 2.5 degrees, the velocity measurement roller surely and smoothly operates in any working condition, friction between the velocity measurement roller and the steel band is little, the surface of the steel band will not be scratched, and production quality is improved.
Description
Technical field
The utility model belongs to stainless steel band production and processing technical field, is specifically related to the production of a kind of glossy surface stainless steel band with the roller that tests the speed.
Background technology
The conventional roller diameter that tests the speed is 250mm, and respectively there are two end caps at two, and during use, the roller that tests the speed is close to steel band, and steel band is hauled by tension force, leans on the motion of steel band to drive the roller rotation of testing the speed.When producing thin steel band, owing to be with thinly, the roller self that tests the speed is heavier, and the motionless roller that tests the speed of steel band band rotates, and directly mistake causes steel strip surface to scratch from testing the speed the roller friction to make steel band, and serious meeting is scrapped steel band, brings greater loss for cold rolling company.
Summary of the invention
The utility model purpose provides the production of a kind of glossy surface stainless steel band with the roller that tests the speed, and the roller that tests the speed running is smooth and easy, and the frictional force between the steel band is little, can not scratch steel strip surface, improves the quality of production.
For achieving the above object, the technical solution adopted in the utility model is: the production of a kind of glossy surface stainless steel band is with the roller that tests the speed, the inner ring interference fit of the axle head of the described roller that tests the speed and self-aligning roller bearing.Above-mentioned self-aligning roller bearing can bear bigger radial load, simultaneously also can bear certain axial load, its outer ring raceway is sphere shape, so have aligning performance, when the stressed bending of axle or inclination and when making inner ring center line and outer ring center line relative tilt be no more than 1 °～2.5 °, the bearing endure, the assurance roller running under any operating mode of testing the speed is smooth and easy, and the frictional force between the steel band is little, can not scratch steel strip surface, improves the quality of production.
In the technique scheme, the endoporus of described self-aligning roller bearing is circular hole.
The endoporus of described self-aligning roller bearing is not limited to circular hole, can also be conical bore, and the tapering of this conical bore is 1: 30～1: 12.
In the technique scheme, the retainer of described self-aligning roller bearing is steel plate pressing cage, polyamide moulding retainer or copper alloy car retainer processed.
In the technique scheme, be roller core between the two described axle heads of the described roller that tests the speed, the outside of this roller core is coated with rubber layer, the weight saving of the roller that tests the speed, and easier drive when steel band passes through does not drive even, and can not scratch steel strip surface yet.
In the technique scheme, the outside of described self-aligning roller bearing is provided with bearing block.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. the utility model is provided with self-aligning roller bearing in the two axial ends of the roller that tests the speed, can bear bigger radial load, simultaneously also can bear certain axial load, its outer ring raceway is sphere shape, so have aligning performance, when the stressed bending of axle or inclination and when making inner ring center line and outer ring center line relative tilt be no more than 1 °～2.5 °, the bearing endure, the roller running under any operating mode that guarantees to test the speed is smooth and easy, and the frictional force between the steel band is little, can not scratch steel strip surface, improve the quality of production.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: referring to Fig. 1, shown in Figure 2, the production of a kind of glossy surface stainless steel band is with the roller that tests the speed, the axle head 10 of the described roller 1 that tests the speed and the inner ring interference fit of self-aligning roller bearing 2, and the outside of described self-aligning roller bearing 2 is provided with bearing block 3.
The endoporus of described self-aligning roller bearing 2 is conical bore, and the tapering of this conical bore is 1: 30～1: 12.
The retainer of described self-aligning roller bearing 2 is steel plate pressing cage, polyamide moulding retainer or copper alloy car retainer processed.
Be roller core 11 between the two described axle heads 10 of the described roller 1 that tests the speed, the outside of this roller core 11 is coated with rubber layer 12, the weight saving of the roller that tests the speed, and easier drive when steel band passes through does not drive even, and can not scratch steel strip surface yet.
The utility model is provided with self-aligning roller bearing in the two axial ends of the roller that tests the speed, can bear bigger radial load, simultaneously also can bear certain axial load, its outer ring raceway is sphere shape, so have aligning performance, when the stressed bending of axle or inclination and when making inner ring center line and outer ring center line relative tilt be no more than 1 °～2.5 °, the bearing endure, the roller running under any operating mode that guarantees to test the speed is smooth and easy, and the frictional force between the steel band is little, can not scratch steel strip surface, improve the quality of production.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
