In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is this utility model Elevator roller and step portion attachment means structural representation in an embodiment.
In accompanying drawing, the labelling of each parts is as follows: 1, roller, and 2, step portion, 3, cylinder connector, 4, flange, 5, shaft housing connector, 6, boss, 7, connecting portion, 8, taper hole, 9, cone connector.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
This utility model embodiment:
Refer to Fig. 1, Elevator roller of the present utility model and step portion attachment means include the resilient shaft housing connector of tool 5 of column, the flange 4 of radially protruding it is provided with on the outer wall of described shaft housing connector 5, the side of described flange 4 is cylinder connector 3, cylinder connector 3 is cylinder, and the opposite side of described flange 4 is cone connector 9.Cylinder connector 3, flange 4 and cone connector 9 three in one connect and form described shaft housing connector 5, in the described taper hole 8 of the boss 6 that described cone connector 9 inserts the connecting portion 7 of described step portion 2, tight fit i.e. interference fit between described cone connector 9 and the taper hole 8 of described boss 6, makes cone connector 9 connect as one with connecting portion 7.Shaft housing connector 5 is elastic component, relies on and applies suitable external force, cone connector 9 is pressed into taper hole 8, makes the one side of described flange 4 prop up boss 6, and shaft housing connector 5 is tightly combined with the connecting portion 7 of step portion 2, and adhesion is big, is difficult to get loose.
Cylinder connector 3 inserts in the bearing in Elevator roller, and flange 4 props up the bearing inner race of bearing, positions.Cylinder connector 3 and bearing inner race tight fit, it is achieved cylinder connector 3 is connected with the fixing of Elevator roller 1.
Such connection need not use glue on the outer wall of shaft housing connector 5, the shaft housing connector 5 elastic deformation when stress is relied on to realize shaft housing connector 5 and Elevator roller 1 and the compact siro spinning technology of step portion 2, the outer end of shaft housing connector 5 blocks also without end cap, simplifying attachment structure, the connection member of use is less, it is possible to reduce manufacturing procedure, reduce production cost, and shaft housing connector 5 is made up of plastic material, is easily worked, material cost and processing cost are low.Being connected firmly of shaft housing connector 5 and Elevator roller 1 and step portion 2, shaft housing connector 5 is not easily separate with Elevator roller 1 and step portion 2, and the service life of whole attachment means is long.
Preferably, the outer wall tangent plane of described cone connector 5 is 1.5 °-5 ° with the angle of the central axis of cone connector 9.This cone angle both can realize in the taper hole 8 of the connecting portion 7 that cone connector 9 is installed into step portion 2 relatively easily, can ensure that again combining closely of cone connector 9 and taper hole 8.
It is appreciated that described cylinder connector 3 and cone connector 9 can also be made up of metal mandrel outer cladding elastomeric material.Rely on the elastomeric material outside metal mandrel and Elevator roller and the tight fit of step portion 2, it is also possible to realize shaft housing connector 5 and Elevator roller 1 and the compact siro spinning technology of step portion 2.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
