Abstract
The utility model relates to a synchronous universal shaft coupling for a short ball cage, which comprises an outer sleeve, an inner sleeve and a middle shaft. The utility model is characterized in that the inner sleeve and the middle shaft are integrally designed into an inner sleeve shaft; an equant tooth slot is arranged on the circumferential edge of the outer sleeve; both inside walls of the coupling are provided with grease baffle covers which are matched with the end surfaces of the inside walls of the coupling and are provided with certain gaps. As the utility model adopts the integrated design of the inner sleeve and the middle shaft, the space of the coupling can be reduced. The coupling with integration structure can achieve the purpose of enhancing the capability of the coupling transferring dynamic force of connection members. Simultaneously, the circumferential edge of the outer sleeve is provided with the groove, and a connection flange and the outer sleeve are in correspondingly tightly convex-concave arrangement. Under the working condition of the coupling, the transfer torque of the outer sleeve can be correspondingly increased, and the capability of the coupling transferring the dynamic force is enhanced.
Description
The utility model relates to a kind of Hooks coupling universal coupling, and what relate to specifically is a kind of short Rzeppa synchronous universal coupling that improves the transferring power ability.
The present short Rzeppa synchronous universal coupling that adopts, its structure includes overcoat, interior cover, jack shaft etc., because interior cover and jack shaft are split type the companies, so its is difficult to satisfied requirement that connects shorter syndeton length; Secondly, owing to be split type connection, after coupling connected driving component, the ability of coupling transfer motion power was restricted, and also was difficult to transmit relatively large power.
The purpose of this utility model is in order to solve the deficiency of existing short Rzeppa synchronous coupling, to provide a kind of and can further reduce to connect spacing, also can increasing the short Rzeppa synchronous universal coupling of coupling transferring power ability simultaneously.
For achieving the goal, the utility model provides following technical solution:
A kind of short Rzeppa synchronous universal coupling comprises overcoat, interior cover and jack shaft, it is characterized in that: cover is the integrated design into interior sleeve with jack shaft in described; Be enclosed within its circumferential edges design outside described the five equilibrium teeth groove is arranged; On coupling two madial walls, be provided with and grease blocking cover that certain interval arranged that match, when the coupling high speed rotating, can prevent that lubricating grease throws away in the coupling with coupling madial wall end face.
Feature of the present utility model is that also in the described interior sleeve, axially both sides are provided with the compression exhaust device.
Feature of the present utility model also is, described compression exhaust device is made of cavity body, the spring be located in the cavity, and wherein, cavity one end is provided with and the extraneous air flue that communicates, and the cavity the other end axially communicates with interior sleeve; The cavity outer end be fixed on the coupling two ends and offset with the collinear baffle plate of coupling end-face.Air flue on the cavity can make coupling two ends cavity form the gas circuit that communicates with center-aisle on the interior sleeve, avoids because of using a certain cavity to form highpressure.This compression exhaust device also has the function of automatic positioning simultaneously, under the elastic force effect, can make the steel ball working position in the coupling normal.
Feature of the present utility model also is, described compression exhaust device is made of cavity body, the piston that is located in the cavity, and wherein, cavity one end is provided with and the extraneous air flue that communicates, and the cavity the other end axially communicates with interior sleeve; Piston is provided with venting channels; The cavity outer end be fixed on the coupling two ends and offset with the collinear baffle plate of coupling end-face.
The utility model has been owing to adopted interior cover and jack shaft integrated design, thereby the coupling spacing is dwindled greatly, and in testpieces embodiment, syndeton length can reach 200 ± 10mm; And the coupling of integral structure also can reach the purpose that coupling is improved at the transmission connection even ability of part power; Simultaneously, overcoat circumferential edges groove design, after making the corresponding convex-concave of connecting flange install closely with overcoat, under the coupling working state, the transmitting torque of overcoat increases relatively, the so also corresponding ability of the transferring power of coupling that makes is improved, and the steel ball working position of automatic positioning function in making coupling of compression exhaust device keeps can improving transmission capacity equally under the normal situation.By test, the working speed of coupling can reach 2400rpm, and engine power 485Kw has surpassed the transferring power ability of at present existing short Rzeppa synchronous universal coupling, thereby reached goal of the invention of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a side view of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, have at the short Rzeppa synchronous universal coupling, interior cover 9 is the integrated design into interior sleeve with jack shaft 6; On coupling two madial walls, grease blocking cover 7 is installed, grease blocking cover 7S shape structure, it matches with retainer 8 end faces that protrude and recessed interior cover 9 end faces on the coupling madial wall and certain interval is arranged, sleeve has certain space in can making like this when move left and right, and can reach prevent the purpose that lubricating grease throws away in the coupling when the coupling high speed rotating.Grease blocking cover 7 one ends are fixed on the coupling overcoat 5 by housing screw, and the other end is fixedly connected on the interior sleeve.The compression exhaust device is arranged in the interior sleeve, the spring of laying in the cavity spring seat 4 that this device is had by the axial both sides of interior sleeve, the spring seat 43 constitutes, spring seat 4 one ends have and the extraneous air flue 2 that communicates, and spring seat 4 the other ends have the passage that axially communicates with interior sleeve; Spring seat 4 outer ends be fixed on the coupling two ends and offset with the collinear baffle plate 1 of coupling end-face.Air flue on the spring seat 4 can make coupling two ends cavity form the gas circuit that communicates with center-aisle on the interior sleeve, avoids because of using a certain cavity to form highpressure.This compression exhaust device also has the function of automatic positioning simultaneously, under the elastic force effect, can make the steel ball working position in the coupling normal.
In Fig. 2, the circumferential edges uniform Design of overcoat has 10, six of 18 trapezoidal teeth groove of five equilibrium to connect 11,1 liftings of screw screw.
In the use, connecting flange is installed closely with the groove 10 corresponding convex-concaves at overcoat 5 edges, other part is gone up by the connection of working method order and is got final product.
