Abstract
The utility model relates to a flattening ring shaft sleeve which comprises a cylindrical shaft sleeve body. The shaft sleeve body is provided with an annular groove which is used for mounting of a retainer ring for a shaft, the annular groove is close to one end of the shaft sleeve body, a protruding ring is arranged at the other end of the shaft sleeve body and provided with a round through hole, the protruding ring and the shaft sleeve body form a whole, and the shaft sleeve body is provided with two symmetrical key slots adjacent to the protruding ring. Since the protruding ring is arranged at one end, without the annular groove, of the shaft sleeve body, uniformity of a flattening ring bearing and the axial positioning size of the flattening ring shaft sleeve can be well guaranteed, and the flattening ring bearing is less prone to loose.
Description
Technical field
The utility model relates to a kind of axle sleeve, especially a kind of axle sleeve that is used for flattening ring member.
Background technique
Flattening ring member is a vitals in the winding film coating machine; Shown in accompanying drawing 1; Flatten ring member and comprise that flattening annulate shaft cover 1, flattening collar bearing 2, flattening ring end cap 3, shaft block ring 4, hole are with back-up ring 5 and flattening ring 6; Flatten annulate shaft cover 1 outer being provided with and flatten collar bearing 2, flattening collar bearing 2 two ends are provided with and flatten ring end cap 3, flatten a pair of shaft block ring 4 that is used for fixing flattening ring end cap 3 is housed on the annulate shaft cover 1; To reach the fixing purpose that flattens collar bearing 2, flatten collar bearing 2 outer holes and be provided with flattening ring 6 with back-up ring 5 through its two ends.In parts, use 12 owing to flatten collar bearing simultaneously; So require its fitted position conformity necessarily will get well; And above-mentioned structure is difficult to guarantee the flattening collar bearing and flattens the conformity that annulate shaft overlaps axial location dimension, and flattens the diameter tolerance precision height of annulate shaft cover, in case the diameter tolerance of flattening annulate shaft cover has satisfied not when requiring; The fixedly flattening collar bearing effect of a pair of shaft block ring will variation, causes flattening collar bearing and takes place loosening.
The model utility content
The utility model purpose is to provide a kind of to can be good at guaranteeing to flatten collar bearing and flatten annulate shaft overlapping the conforming flattening annulate shaft cover of axial location dimension for the deficiency that overcomes existing technology.
For achieving the above object; The technological scheme that the utility model adopts is: a kind of flattening annulate shaft cover, comprise columned axle sleeve body, and have the annular groove that is used to install shaft block ring on the said axle sleeve body; Said annular groove is near an end of axle sleeve body, and the other end of said axle sleeve body is provided with bulge loop.
Preferably, said bulge loop and axle sleeve body are as a whole.
Preferably, have circular hole on the said bulge loop; Said circular hole is a through hole.
Preferably, have keyway on the said axle sleeve body; Said keyway and bulge loop are adjacent.
Preferably, said keyway symmetry has two.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The flattening annulate shaft cover of the utility model; Because the axle sleeve body is not provided with an end of annular groove and is provided with bulge loop; Acting in conjunction through bulge loop and shaft block ring fixes the flattening collar bearing; Can be good at guaranteeing to flatten collar bearing and flattening the conformity that annulate shaft overlaps axial location dimension, flatten collar bearing and be difficult for taking place to become flexible phenomenon.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the structural representation of the flattening ring member of existing technology;
Accompanying drawing 2 is the structural representation of the flattening annulate shaft cover of the utility model;
Accompanying drawing 3 is the user mode schematic representation of the flattening annulate shaft cover of the utility model;
Wherein: 1, flatten the annulate shaft cover; 2, flatten collar bearing; 3, flatten the ring end cap; 4, shaft block ring; 5, back-up ring is used in the hole; 6, flatten ring; 7, axle sleeve body; 8, annular groove; 9, bulge loop; 10, circular hole; 11, keyway; 12, elastic cylindrical pin; 13, dish spring.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of flattening annulate shaft cover of the utility model shown in accompanying drawing 2 comprises columned axle sleeve body 7, has the annular groove 8 that is used to install shaft block ring 4 on the said axle sleeve body 7; Said annular groove 8 is near an end of axle sleeve body 7; The other end of said axle sleeve body 7 is provided with the bulge loop 9 as a whole with axle sleeve body 7; Have circular hole 10 on the said bulge loop 9; Said circular hole 10 is a through hole; Also have a pair of keyway 11 adjacent on the said axle sleeve body 7 with bulge loop 9.
Shown in accompanying drawing 3, axle sleeve body 7 is fixing through the elastic cylindrical pin in the circular hole 10 12, and bulge loop 9 contacts with a flattening ring end cap 3, and shaft block ring 4 flattens ring end cap 3 with another and contacts.Shaft block ring 4 and flattening encircle 3 of end caps can also be provided with dish spring 13, can be good at guaranteeing to flatten collar bearing 2 and flattening the conformity that annulate shaft overlaps 1 axially locating size, flattens collar bearing 2 difficult generations and becomes flexible phenomenon.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
Claims (5)
1. one kind flattens the annulate shaft cover, comprises columned axle sleeve body, has the annular groove that is used to install shaft block ring on the said axle sleeve body, and said annular groove is characterized in that near an end of axle sleeve body: the other end of said axle sleeve body is provided with bulge loop.
2. flattening annulate shaft cover according to claim 1 is characterized in that: said bulge loop and axle sleeve body are as a whole.
