Technical field
The utility model relates to a kind of Hooks coupling universal coupling, especially relates to a kind of two ball universal coupling that drives.
Background technique
Hooks coupling universal coupling is a kind of driving component in industry extensive uses such as metallurgy, chemical industry, automobile, shipbuildings, and it is mainly used in connecting out of line diaxon or diaxon system.Now, the power transmission medium of ball universal coupling is steel ball both at home and abroad, because of universal requirement, each raceway can only be set up unique steel ball, and the route of transmitting torque is from the internal tooth of input end to external tooth, then passed to the external tooth of output terminal by jack shaft, be delivered to internal tooth, and then to working machine, therefore, roller surface is easy to damage, and working life is short.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides two ball universal couplings that drive that a kind of long service life, boundary dimension are little.
The technical solution adopted in the utility model is: comprise internal tooth, steel ball, external tooth, all carry device, yoke and roller, described external tooth one end is provided with multiple driving cogs, the outer circumferential face of driving cog is sphere, on the side of driving cog, be respectively equipped with a steel ball raceway, external tooth end face center is provided with through hole along axial direction, and through hole is spline housing away from transmission increment; Corresponding to the driving cog of external tooth, one end of described internal tooth endoporus is provided with groove, is respectively equipped with the raceway corresponding with steel ball raceway on the bi-side of groove; The driving cog of external tooth is inlaid in the groove that internal tooth is corresponding, in the lacuna that the steel ball raceway that described steel ball is arranged on driving cog forms with the raceway on corresponding groove side; The other end sidewall of described internal tooth endoporus is provided with two gyro wheeling concrete chutings; The described spline that all carries device is inserted in the endoporus of external tooth, coordinates with the spline housing of external tooth, and the crossbeam that all carries device is positioned at the endoporus of internal tooth, is connected with yoke; The crossbeam two ends of yoke are respectively equipped with a roller, and roller is inlaid in corresponding gyro wheeling concrete chuting.
Above-mentioned two driving in ball universal coupling, described external tooth is provided with three driving cogs, and what one end of described internal tooth endoporus was corresponding is provided with three grooves.
Above-mentioned two driving in ball universal coupling, the described spline all carrying on device is involute splines.
Compared with prior art, the beneficial effects of the utility model are:
1. internal tooth of the present utility model and all carry simultaneously transmitting torque of device, has improved the moment of torsion transmitting greatly.
2. between the utility model internal tooth and external tooth, be provided with multiple steel balls, by multiple steel ball transmitting torques, and all carry device and transmit a part of moment of torsion, the moment of torsion that an original steel ball is born is by multiple steel balls and all carry device and bear, the suffered pressure of the residing steel ball raceway of single steel ball is reduced, roller surface is not easy by conquassation, and the roller surface of steel ball increases working life, therefore long service life of the present utility model.
3. the utility model is by internal tooth with all carry simultaneously transmission of device, with respect to existing ball universal coupling, to material property require lowly, and in the situation of transmission same load, size of the present utility model is little.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, 2, the utility model comprises internal tooth 1, steel ball 2, external tooth 3, all carries device 4, yoke 5 and roller 6, as shown in Figure 2,3, described external tooth 3 one end are provided with three driving cogs 31, the outer circumferential face of driving cog 31 is sphere, on the side of driving cog 31, be respectively equipped with a steel ball raceway 32, external tooth 3 end face centers are provided with through hole 33 along axial direction, through hole 33 be spline housing 34 away from transmission increment.As Figure 4-Figure 6, corresponding to three driving cogs 31 of external tooth 3, what one end of described internal tooth 1 endoporus was corresponding is provided with three grooves 11, is respectively equipped with the raceway corresponding with steel ball raceway 32 12 on the bi-side of groove 11, and the other end of the endoporus of internal tooth 1 is provided with two gyro wheeling concrete chutings 13.The driving cog 31 of external tooth 3 is inlaid in the groove 11 of internal tooth 1 correspondence, in the lacuna that the steel ball raceway 32 that described steel ball 2 is arranged on driving cog 31 forms with the raceway 12 on corresponding groove 11 sides; The described spline that all carries device 4 is inserted in the endoporus 33 with external tooth 3, coordinates with the spline housing 34 of external tooth 3; The crossbeam that all carries device 4 is positioned at the endoporus of internal tooth 1, is connected with yoke 5.Crossbeam 51 two ends of yoke 5 are respectively equipped with a roller 6, and roller 6 is inlaid in corresponding gyro wheeling concrete chuting 13.The described spline that all carries device 4 is involute splines.
