Abstract
The utility model relates to an elastic coupling with internal teeth in the field of mechanical drive. The utility model is characterized in that the middle part of the inner wall of an elastic sleeve is provided with a circle of cam bearings, and the inner walls on both sides of the cam bearings are both provided with internal teeth. The internal teeth mesh with the external teeth of a driven shaft sleeve and of a driving shaft sleeve. The utility model has the advantages of simple structure, convenient installation, low noise, low cost, small loss of rotative power and long service life, and permits large displacement in both axial direction and radial direction. The resisting torque of the utility model is multiple times of that of the existing products, thus, the utility model is an ideal upgrade product among the national similar products.
Description
The utility model relates to the coupling of mechanical transmission fields, especially a kind of internal tooth form elastic coupling flexible coupling.
Present domestic employed coupling, as rigid coupling, flexible coupling etc., generally do not allow bigger axially, radially or angular displacement.China's utility model patent (application number is 922219036,87206169) discloses two kinds of gear couplings, and they all adopt two half-couplings, though technical order can reach requirement, but structure is very complicated, and technological requirement is very high, and cost is also high.
The purpose of this utility model is to overcome the deficiency of prior art and provides that a kind of structure is very simple, cost is low and allow the internal tooth form elastic coupling flexible coupling of bigger axial displacement, radial displacement and angular displacement.
The purpose of this utility model is achieved in that
Have in the middle of the resilient sleeve inwall of the present utility model on the inwall of a protruding beam of circle and protruding beam both sides all that symmetry is shaped on internal tooth, driven axle sleeve and driving axle housing also are shaped on the external tooth that is meshed with the resilient sleeve internal tooth.
Resilient sleeve of the present utility model is made by strengthening the monomer cast nylon elastomeric material.
Advantage of the present utility model and good effect are:
Coupling only is made of resilient sleeve, driving axle housing and driven axle sleeve, and structure is very simple, makes easily, and cost is low; Resilient sleeve is made by strengthening the monomer cast nylon elastomeric material, and adopts internal tooth form to connect, can allow bigger axially, radially and angular displacement, and easy for installation, noise is low, the rotative power loss is little, long service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
The protruding fine strain of millet 5 of one circle is arranged in the middle of the inwall of resilient sleeve 3, and all symmetry is shaped on internal tooth 2 on the inwall of protruding fine strain of millet both sides.Also be shaped on the external tooth 4 that is meshed with the tooth of resilient sleeve inwall with resilient sleeve inwall connecting part on driven axle sleeve 1 and the driving axle housing 6, the material of resilient sleeve is made by strengthening the monomer cast nylon elastic material.The effect of protruding fine strain of millet is spacing to driven axle sleeve and driving axle housing.
