Abstract
The invention belongs to the technical field of mechanical equipment, and particularly relates to a cantilever shaft locking mechanism. The cantilever shaft locking mechanism comprises a shaft and a mounting hole for accommodating the shaft, and is characterized in that the middle part of the shaft is provided with a limiting shoulder; the mounting end of the shaft is inserted in the mounting hole; the limiting shoulder locks the edge of the mounting hole; the mounting end of the shaft is provided with a radial half-cut notch; the shaft is divided into a shaft body and an elastic body by the half-cut notch; the shaft body and the elastic body are provided axial screw holes; and the elastic body is connected with the shaft body through locking screws. The cantilever shaft locking mechanism has a simple and skillful structure and a simple appearance, performs the self-locking function by using the self deformation of the shaft, saves the cost, and has a high space utilization ratio and a very high utility value.
Description
Technical field
The invention belongs to mechanical equipment technical field, especially relate to a kind of cantilever shaft locking mechanism.
Background technique
At present, axle is installed in general employing mounting type shown in Figure 1 on the wallboard: offer a mounting hole on wallboard, the mounting end of axle inserts in the mounting hole, and axle is provided with flange plate, and flange plate and wallboard on the axle fix by screw.Though firmly degree is pretty good for such mounting type, needs to be provided with flange plate on the axle, not only can cause space availability ratio low, and waste material, and then has increased the cost of equipment, cause the waste of resource, increased the burden of enterprise.Simultaneously, the efficient of installation is lower, and labor intensity is bigger, when needing repairing, dismantles very inconveniently, has further increased entreprise cost, incompatible present development situation.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of simple and ingenious structure is provided, outward appearance is brief, saves cost and the high cantilever shaft locking mechanism of space availability ratio.
According to technological scheme provided by the invention, described cantilever shaft locking mechanism comprises axle and is used for the mounting hole of ccontaining axle, it is characterized in that, the middle part of axle is provided with spacing shoulder, and the mounting end of axle inserts in the mounting hole, and the limited shoulder decometer is lived the mounting hole limit, the mounting end of axle offers hemisection notch radially, axle is divided into a body and elastomer two-part by the hemisection notch, offers axial screw hole on axle body and the elastomer, and elastomer links to each other by lock screw with the axle body.
As a further improvement on the present invention, the part that is positioned at mounting hole on the described axle also offers seal groove, suit seal ring in the seal groove.
The present invention compared with prior art, advantage is: simple and ingenious structure, outward appearance is brief, the function of utilizing the deformation of axle self to carry out oneself's locking is saved cost and space availability ratio height, has very high use value.
Description of drawings
Fig. 1 is the structural representation of traditional cantilever shaft locking mechanism.
Fig. 2 is a structural representation of the present invention.
Description of reference numerals: 1-gear, 2-bearing, 3-axle, 3a-axle body, 3b-elastomer, the spacing shoulder of 4-, 5-wallboard, 6-hemisection notch, 7-lock screw, 8-mounting hole, 9-seal groove, 10-seal ring.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 2, the present invention mainly is made up of axle 3, lock screw 7 and seal ring 10.The present invention is used for gear 1 is installed in wallboard 5, offer the mounting hole 8 that is used for ccontaining axle 3 on the wallboard 5, gear 1 adopts bearing 2 to be installed in an end of axle 3, the middle part of axle 3 is provided with spacing shoulder 4, the mounting end of axle 3 inserts in the mounting hole 8, spacing shoulder 4 blocks mounting hole 8 limits, the mounting end of axle 3 offers hemisection notch 6 radially, axle 3 is divided into a body 3a and elastomer 3b two-part by hemisection notch 6, offer axial screw hole on axle body 3a and the elastomer 3b, elastomer 3b links to each other by lock screw 7 with axle body 3a, when lock screw 7 turns, elastic strain takes place and tightens the inwall of mounting hole 8 in elastomer 3b, reaches the purpose of stationary axle 3, cost savings and space availability ratio height; The part that is positioned at mounting hole 8 on the described axle 3 also offers seal groove 9, suit seal ring 10 in the seal groove 9.
