Description
Technical field
The present invention relates to a kind of Hooks coupling universal coupling, especially relate to a kind of pair and drive ball universal coupling.
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 domestic and international ball universal coupling is steel ball, because of universal requirement, each raceway can only set up unique steel ball, and namely the route of transmitting torque is from the internal tooth of input end to external tooth, then the external tooth of output terminal is passed to 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 invention provides little two of a kind of long service life, boundary dimension and driving ball universal coupling.
The technical solution used in the present invention is: comprise internal tooth, steel ball, external tooth, all carry device, yoke and roller, described external tooth one end is provided with multiple driving cog, the outer circumferential face of driving cog is sphere, the side of driving cog is respectively equipped with a steel ball raceway, external tooth end face center is provided with through hole in the 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, and the bi-side of groove are respectively equipped with the raceway corresponding with steel ball raceway; The driving cog of external tooth is inlaid in groove corresponding to internal tooth, in the lacuna that the steel ball raceway that described steel ball is arranged on driving cog and the raceway on corresponding groove side are formed; The other end sidewall of described internal tooth endoporus is provided with two gyro wheeling concrete chutings; The described spline all carrying device is inserted in the endoporus of external tooth, coordinates with the spline housing of external tooth, and the crossbeam all carrying 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 twoly drive 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 twoly drive in ball universal coupling, the described spline all carried on device is involute splines.
Compared with prior art, the invention has the beneficial effects as follows:
1. internal tooth of the present invention and all carry device simultaneously transmitting torque, substantially increases the moment of torsion of transmission.
2. be provided with multiple steel ball between internal tooth of the present invention and external tooth, by multiple steel ball transmitting torque, and all carry device and transmit a part of moment of torsion, the moment of torsion born by an original steel ball is by multiple steel ball and all carry device and bear, the pressure suffered by steel ball raceway residing for 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 invention.
3. the present invention is by internal tooth with all carry device simultaneously transmission, relative to existing ball universal coupling, low to the requirement of material property, and when transmission same load, size of the present invention is little.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, 2, the present invention includes internal tooth 1, steel ball 2, external tooth 3, all carry device 4, yoke 5 and roller 6, as shown in Figure 2,3, described external tooth 3 one end is provided with three driving cogs 31, the outer circumferential face of driving cog 31 is sphere, the side of driving cog 31 is respectively equipped with a steel ball raceway 32, external tooth 3 end face center is provided with through hole 33 in the 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, and the bi-side of groove 11 are respectively equipped with the raceway 12 corresponding with steel ball raceway 32, 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 and the raceway 12 on corresponding groove 11 side are formed; The described spline all carrying device 4 is inserted in the endoporus 33 with external tooth 3, coordinates with the spline housing 34 of external tooth 3; The crossbeam all carrying 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 all carrying device 4 is involute splines.
During use, moment of torsion is passed to external tooth 3 by steel ball 2 by internal tooth 1, and meanwhile, moment of torsion to be passed to by roller 6, yoke 5 and all carries device 4 by internal tooth 1; Because the spline all carrying device 4 is inserted in the endoporus 33 with external tooth 3, coordinate with the spline housing 34 of external tooth 3; Therefore, moment of torsion passes to external tooth 1 by the spline all carried on device 4.In the transmittance process of moment of torsion, internal tooth 1 of the present invention and transmitting torque while of all carrying device 4, substantially increase the moment of torsion of transmission.Internal tooth 1 of the present invention and all carry device 4 simultaneously transmitting torque, therefore, part moment of torsion is only had to be transmitted by multiple steel ball 2, when transmitting same torque, the moment of torsion transmitted by steel ball 2 is reduced, and the pressure suffered by steel ball raceway 32 residing for single steel ball 2 is reduced, and roller surface is not easy by conquassation, the roller surface of steel ball 2 increases working life, therefore long service life of the present invention.
