Embodiment
The below contrasts accompanying drawing, and the description by to embodiment is described in further detail the specific embodiment of the present invention, to help those skilled in the art inventive concept of the present invention, technological scheme is had more complete, accurate and deep understanding.
The of the present invention structure expressed such as Fig. 1, be a kind of right angle gear transmission case, comprise casing 3, input shaft 1, main shaft 5, described input shaft 1 is orthogonal with main shaft 5, described input shaft 1 is provided with driving gear 4, described main shaft 5 is provided with driven gear 6, and described driving gear 4 and driven gear 6 are intermeshing bevel gear.
Casing 3 is cast member, and material is HT200.
In order to solve the problem that prior art exists and to overcome its defective, realize improving the ability of transferring power, and improve the goal of the invention of the stationarity of transmission, the technological scheme that the present invention takes is:
As shown in the figure, right angle gear transmission case provided by the present invention, described driving gear 4 and driven gear 6 are the helical bevel gear structure.
Working principle of the present invention:
Power is through input shaft 1 input, and by a pair of helical bevel gear, namely driving gear 4 and driven gear 5 pass to main shaft 5 with power, and main shaft 5 is hollow shaft.Pass a vertical pivot in the main shaft 5, by coupling 9 main shaft 5 is connected with the axle of working machine, thereby working machine is passed in power and the motion of input shaft 1.
The modulus of described driving gear 4 and driven gear 6 is 6mm.
Driving gear 4 and driven gear 5 adopt the helical bevel gear structure, and modulus is 6, has greatly improved the ability of transferring power, and stable drive.
