Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
As shown in fig. 1, the utility model provides a bearing roller convenient to change, including bearing roller axle 1, the cover is established at bearing roller cover 2 outside bearing roller axle 1, be equipped with bearing 3 and bearing roller shaft 1 interference between bearing roller axle 1 and the bearing roller cover 2 and be connected, be equipped with mount 4 between bearing 3 and the bearing roller cover 2, all set up corresponding first screw hole 12 on mount 4 and the bearing roller cover 2, it has screw 7 that is used for fixed mount 4 and bearing roller cover 2 positions to peg graft in the first screw hole 12.
It should be noted that, in this example, the fixing frame 4 and the roller sleeve 2 are fixed by using the first threaded hole 12 formed in the screw 7 to penetrate through the fixing frame 4 and the roller sleeve 2, and the fixing mode is simple, and the roller is convenient to detach and replace.
As shown in fig. 2, a plurality of thread grooves 9 are formed in the surface of the bearing 3, a second threaded hole 13 matched with the thread grooves 9 is formed in the inner wall of the fixing frame 4, a bolt 8 is connected in the second threaded hole 13 in a penetrating manner, and the bottom of the bolt 8 is located in the thread groove 9. Utilize bolt 8 to pass second screw hole 13 and thread groove 9 to rotate, to fixed between mount 4 and the bearing 3, and convenient dismantlement, be convenient for clearance and maintenance.
The gauze 5 is adhered in the fixing frame 4. The fixing frame 4 is of a hollow structure, the gauze 5 is bonded at the hollow structure, and dust can be prevented from entering under the effect of ensuring ventilation and cooling in the carrier roller.
In one embodiment, a plurality of symmetrically distributed bumps 6 are connected to both ends of the carrier roller shaft 1. As shown in fig. 3, eight bumps 6 are selected, two of the bumps are arranged up and down to form a group, the group is four, one end of the carrier roller shaft 1 is distributed in two groups, the other end of the carrier roller shaft 1 is distributed to form a remaining group, the interval between the two groups at one end is distributed to meet the requirement that the carrier roller shaft 1 is placed on transmission equipment of a belt conveyor, the two groups of bumps 6 at one end of the carrier roller shaft 1 are located at two ends of the transmission equipment of the belt conveyor, the position of the carrier roller shaft 1 moving on the belt conveyor is fixed, and deviation is avoided when the carrier.
