Background technology
At present, high speed development along with automobile industry, a kind of roller conveyor that is used to carry sled (utensil of bearing automobile chassis and vehicle frame) is extensive use of by auto trade, its version is: arrange one group of (4-10) carrying roller on the general frame, and between each carrying roller by the cog belt connection that is meshing with each other, all carrying rollers rotate synchronously under the drive of actuating device, thereby reach the purpose of carrying sled, carrying roller generally has the roller that polyurethane encapsulate layer and side have baffle ring by the outer ring, bearing, the profile of tooth belt wheel, axle, composition such as hollow shaft and fastener, yet there are some defectives in the job operation and the version of the carrying roller that continuity is always used, as shown in Figure 3:
1) roller divides two kinds of A, B, is not easy to tissue production;
2) roller A, B adopt welding manner with being connected of hollow shaft, are easy to generate distortion, and right alignment is difficult to guarantee, and is overproof easily;
3) also adopt welding method between profile of tooth belt wheel and the roller A, the high temperature that produces in welding process makes the polyurethane encapsulate layer fusing on the roller easily;
4) core wheel of A, two kinds of rollers of B needs to be shaped through machine up (cutting), and stock utilization and capacity rating are low, and cost is higher;
5) roller B is two baffle ring structures, when machined polyurethane encapsulate layer, can only connect back-up ring (being subjected to the encapsulate process limitation) by a face down bonding, and opposite side needs to weld behind encapsulate again, has the easily problem of fusing of encapsulate layer equally.And a shelves boxing needs secondary machining seam end face after connecing, and strengthened manufacturing cost;
6) the polyurethane encapsulate layer of roller easily takes place and the core wheel obscission in the long-term use process.
Existing in sum idler structure brings very big difficulty for the processing of raising carrying roller, installation, debugging quality.
Summary of the invention
The purpose of this utility model provides a kind of carrying roller that is used on the roller conveyor, reduces machining amount, saves raw MAT'L, reduces production costs the polyurethane encapsulate layer on the raising roller and the binding force of core wheel, the setting accuracy of assurance carrying roller.
The purpose of this utility model realizes by following technical proposals:
The carrying roller that is used on the roller conveyor of the present utility model, comprise frame fixation bonded assembly axle with roller conveyor, the two bearings that is connected of axle both ends therewith respectively, be located between this two bearings and be enclosed within hollow shaft on the described axle, the roller A and the roller B that are connected of the outside face at hollow shaft two ends therewith respectively, the profile of tooth belt wheel that is connected of the outside face of hollow shaft one side therewith, the outside face that it is characterized in that described hollow shaft two ends is provided with plane of orientation, described roller A is by the core wheel that is connected with described bearing outside surface and hollow shaft outside face, the polyurethane encapsulate layer that casts on the outside face of this core wheel is abutted against mutually and forms by the baffle ring that fastener is captiveed joint with the side of described core wheel with a side of polyurethane encapsulate layer therewith, the internal bore profile shape of described core wheel is consistent with the cross section outer contour shape that has plane of orientation at described hollow shaft both ends, and described roller B and roller A are identical components.
Vertically evenly be provided with one group of dovetail furrow on the outside face of described core wheel.
Half outside face of described core wheel is provided with minus thread, and second half outside face of described core wheel is provided with right-hand screw thread.
Described one group of dovetail furrow quantity is 4～6.
Described core wheel is formed by die cast by powdered metallurgical material.
Advantage of the present utility model:
What 1) roller A, B adopted is the identical member of version, is convenient to tissue production;
2) roller and hollow shaft connecting bridge adopt the plane of orientation mode, realize solderless access node structure, avoid the problem of welding deformation and fusing, injury polyurethane encapsulate layer, need not postwelding processing, reduce production process, reduce production costs;
3) roller adopts less or does not have cutting technology, and both the partial metallurgy die cast formed, and saving in material has improved capacity rating;
4) baffle ring and roller adopt fastener to assemble, and the cancellation welding sequence is avoided the easily problem of fusing of polyurethane encapsulate layer, has improved capacity rating;
5) the wheel core outer surface is provided with four dovetail furrows and left and right hand thread, so it is stronger to cast in polyurethane encapsulate layer and the binding force of core wheel of wheel on the core outer surface.And the polyurethane encapsulate pull-up phenomenon that falls because the screw thread self-locking action, all can not take place in no matter roller cw or inverse time rotation;
6) the utility model welding sequence is few, and the assembly quality height is easy to make, and is with low cost, good looking appearance, and dependable performance, the life-span is long.
