Abstract
A kind of split type snap ring back-up ring, comprise subdivision back-up ring and lower subdivision back-up ring, upper subdivision back-up ring is by first through hole of its one end and the first tapped hole first screw of lower subdivision back-up ring one end, first packing ring connects, second through hole of the lower subdivision back-up ring the other end and the second tapped hole second screw of the upper subdivision back-up ring the other end, second packing ring connects, upper subdivision back-up ring, lower subdivision back-up ring is arranged in the groove on axle, one puts subdivision back-up ring and lower subdivision back-up ring connects into an entirety, the both sides of part configure one respectively and put subdivision back-up ring and lower subdivision back-up ring, when part is subject to thrust load, the side of part is tightly against on upper subdivision back-up ring and lower subdivision back-up ring, upper subdivision back-up ring and lower subdivision back-up ring are again tightly against the side of the groove of axle, therefore the first screw, second screw no longer bears the plus load because axial force causes, avoid the first screw, the distortion of the second screw, fracture, make split type snap ring back-up ring can bear large axial force.
Description
Technical field
The utility model relates to a kind of axial direction positioning device of parts on shaft, particularly relates to a kind of split type snap ring back-up ring.
Background technique
At present, the axially locating of existing parts on shaft ensures with screw lock baffle ring, because screw lock baffle ring can replace the shaft shoulder to locate, so solve the problem that parts on shaft too much cannot assemble because the shaft shoulder, also can save the material of axle simultaneously.When parts on shaft is by axial force, the screw on screw lock baffle ring is also subject to corresponding power, but if when the parts on shaft axial force of bearing is excessive, easily makes screw deform, rupture, therefore cause screw lock baffle ring can not bear large axial force.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of split type snap ring back-up ring, and structure is simple, can axial restraint parts on shaft, more can bear large axial force.
In order to achieve the above object, the technical solution of the utility model is achieved in that
A kind of split type snap ring back-up ring, comprise subdivision back-up ring 1 and lower subdivision back-up ring 4, upper subdivision back-up ring 1 is connected with first tapped hole 3 of lower subdivision back-up ring 4 one end the first screw 5, first packing ring 6 by first through hole 2 of its one end, second through hole 9 of lower subdivision back-up ring 4 the other end is connected with the second tapped hole 10 of upper subdivision back-up ring 1 the other end the second screw 11, second packing ring 12, and upper subdivision back-up ring 1, lower subdivision back-up ring 4 are arranged in the groove 8 on axle 7.
Advantage of the present utility model: structure is simple, assembling easily, saves the material of axle, can axial restraint parts on shaft, more can bear large axial force.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is fundamental diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and working principle are described in detail.
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of split type snap ring back-up ring, comprise subdivision back-up ring 1 and lower subdivision back-up ring 4, upper subdivision back-up ring 1 is connected with first tapped hole 3 of lower subdivision back-up ring 4 one end the first screw 5, first packing ring 6 by first through hole 2 of its one end, second through hole 9 of lower subdivision back-up ring 4 the other end is connected with the second tapped hole 10 of upper subdivision back-up ring 1 the other end the second screw 11, second packing ring 12, and upper subdivision back-up ring 1, lower subdivision back-up ring 4 are arranged in the groove 8 on axle 7.
Working principle of the present utility model is:
With reference to Fig. 3, one puts subdivision back-up ring 1 and lower subdivision back-up ring 4 connects into an entirety, the both sides of part 13 configure one respectively and put subdivision back-up ring 1 and lower subdivision back-up ring 4, when part 13 is subject to thrust load, the side of part 13 is tightly against on upper subdivision back-up ring 1 and lower subdivision back-up ring 4, upper subdivision back-up ring 1 and lower subdivision back-up ring 4 are again tightly against the side of the groove 8 of axle 7, therefore the first screw 5, second screw 11 no longer bears the plus load because axial force causes, avoid the first screw 5, the distortion of the second screw 11, fracture, make split type snap ring back-up ring can bear large axial force.
Claims (1)
