Detailed Description
To make the objects, contents and advantages of the present utility model more apparent, the following detailed description of the present utility model will be given with reference to the accompanying drawings and examples.
The structure of the elastic coupling device of the rubber gear is shown in fig. 1, and the elastic coupling device comprises a shaft end nut 1, a transmission device input shaft 2, an elastic coupling gear assembly 3, a gear ring 4 and a power output disc 11. Wherein, the external spline end of the transmission input shaft 2 is inserted into the internal spline hole of the elastic coupling gear assembly 3 and locked by the shaft end nut 1. The end face of the ring gear 4 is connected to a power take-off disc 11 by means of a first bolt 9 and a first spring washer 10. The elastic coupling gear assembly 3 is connected with tooth sockets of the gear ring 4 in a matched mode through external teeth. The power is transmitted from the power take-off disc 11 to the transmission input shaft 2 via the ring gear 4 and the elastic coupling gear assembly 3 in sequence.
As shown in fig. 2a to 2c, the elastic coupling gear assembly 3 includes an assembly body, an elastic coupling gear 12, and rubber teeth 13. Wherein, the center of the assembly main body is provided with an involute inner spline hole, and the involute inner spline hole is connected with the input shaft 2 of the transmission device through an involute spline. The elastic coupling gear 12 including 18 circular arc tooth surfaces is uniformly arranged in the circumferential direction of the assembly body, as shown in fig. 3a and 3 b. In this embodiment, the material of the elastic coupling gear 12 is 38CrSi alloy steel having a heat-treated hardness of 254 to 302HB. The rubber teeth 13 are wrapped on the teeth of the elastic coupling gear 12 through a vulcanization process to form a non-detachable integrated gear. The rubber teeth 13 are made of high-strength composite rubber, and have the performances of high temperature resistance, extrusion resistance, wear resistance and oil resistance, and the thickness of the vulcanized tooth rubber is 8mm. Rubber vulcanization is adopted on the high-strength alloy steel gear, so that the elastic coupling gear assembly 3 not only can transmit large torque, but also can reduce power transmission vibration and impact to a great extent. After the rubber teeth 13 are vulcanized, the end faces of the teeth are provided with round corners of R5, and the structure is convenient for the outer teeth of the elastic coupling gear assembly 3 to be smoothly inserted into tooth grooves of the gear ring 4 during the integral power transmission assembly.
As shown in fig. 4a and 4b, tooth grooves with 18 circular arc tooth surfaces are uniformly arranged in the circumferential direction of the gear ring 4, and are in clearance fit with the external teeth of the elastic coupling gear assembly 3 by 0.1-0.3 mm, so that the transmission device box body 5 is conveniently in butt joint with the power device box body 8. In this embodiment, the material of the ring gear 4 is 38CrSi alloy steel having a heat treatment hardness of 254 to 302HB.
According to the elastic coupling device, through the structural connection, the power transmission integrated assembly can be easily realized, the elastic coupling gear assembly 3 is only required to be rotated during the power transmission butt joint assembly, and after the external teeth of the elastic coupling gear assembly 3 enter the tooth sockets corresponding to the tooth rings 4, the transmission device box body 5 is connected with the power device box body 8 through the second bolts 6 and the second spring washers 7, so that the power transmission integrated assembly is completed.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and variations could be made by those skilled in the art without departing from the technical principles of the present utility model, and such modifications and variations should also be regarded as being within the scope of the utility model.
