[0002] Differential bevel gears are mostly produced by gear rolling machines. The working principle of the gear rolling machine is simple, that is, two gear rolling plates moving in opposite directions move on the gear shaft. When the teeth on the gear rolling plates roll over the surface of the wheel shaft, the gear keys will be rolled to form the gear shaft. However, the existing gear rolling machines still have certain shortcomings when used:

[0003] The main mechanism for gear rolling in a gear rolling machine is a gear rolling plate. In the prior art, the gear rolling plate is usually fixedly mounted on a frame. When replacing it, it is necessary to unscrew all the fixing bolts and then install a new gear rolling plate.

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] Example 1

[0023] See also Figure 1-4 A gear rolling machine for differential bevel gears, comprising a pair of frames 1 mounted on the gear rolling machine, a gear rolling plate 2 mounted on the frame 1, and a driving module 3 driving the two frames 1 to move toward each other, wherein the gear rolling plates 2 are provided with a plurality of them, the frame 1 is in an arch shape, a mounting shaft 4 is rotatably mounted in the frame 1, a column 5 is fixedly mounted on the mounting shaft 4, the cross section of the column 5 is a regular polyhedron structure, a plurality of gear rolling plates 2 are fixedly mounted on a plurality of side surfaces of the column 5 in a one-to-one correspondence, and a knob is installed at one end of the mounting shaft 4 which passes through the outside of the frame 1 6, a brake assembly for limiting the rotation of the mounting shaft 4 is installed at the other end. By setting the mounting shaft 4, the column 5, the brake assembly and the plurality of toothed plates 2, when the knob 6 at the end of the mounting shaft 4 is rotated, the column 5 can be driven to rotate, and the plurality of toothed plates 2 on the side of the column 5 can be driven to move successively to the outside of the seat frame 1, so as to realize the replacement of the toothed plates 2. After the replacement is completed, the brake assembly can quickly fix the position of the toothed plates 2. Compared with the prior art in which the toothed plates 2 are fixed on the seat frame 1 by bolts, it has the advantages of simple operation and convenient replacement.

[0024] The brake block 11 is movably mounted on the mounting plate 8 by means of the spring 10, and a pull ring 13 is mounted on one end of the movable rod 9, and a brake block 11 is fixedly mounted on the other end of the movable rod 9. The disc 7 is coaxially fixedly mounted on the other end of the mounting shaft 4, and an array of brake grooves 12 with the same number as the toothed plate 2 is arranged on the disc 7, and the brake block 11 is movably inserted in the brake groove 12. Specifically, when the toothed plate 2 needs to be replaced, the pull ring 13 at one end of the seat frame 1 is first pulled to pull the brake block 11 out of the brake groove 12 of the disc 7, and then the knob 6 at the other end of the seat frame 1 is rotated until the required toothed plate 2 is rotated outside the seat frame 1, and finally the pull ring 13 is released, and the brake block 11 can be reinserted into the brake groove 12 under the action of the spring 10, and the position of the column 5 and the toothed plate 2 is fixed.

[0025] The tooth-rolling plate 2 is detachably mounted on the column 5 by means of a plurality of screws. By means of such an arrangement, before production, a plurality of tooth-rolling plates 2 can be pre-installed on the side of the column 5 according to demand, and the conversion of a plurality of tooth-rolling plates 2 can be realized.

[0026] Example 2

[0027] This embodiment is improved on the basis of embodiment 1, specifically:

[0028] See also Figure 2 and Figure 4 The seat frame 1 is also symmetrically hinged with side panels 14 on both sides, and a plurality of fastening screws 15 are movably installed on the side panels 14. The side of the column 5 is provided with threaded holes 16 adapted to the fastening screws 15, wherein four fastening screws 15 are provided, and the four fastening screws 15 are arranged in a rectangular shape on the side of the side panel 14 near the end. The side panels 14, fastening screws 15 and threaded holes 16 are arranged so that after the brake assembly brakes and limits the mounting shaft 4, the side panels 14 can be flipped to a vertical state, and the fastening screws 15 can be screwed with a tool so that the fastening screws 15 are inserted on the side of the column 5. In this way, the stability of the gear rolling plate 2 during operation is further improved.

[0029] Furthermore, when the side plate 14 is flipped upward and the column 5 is driven to rotate, in order to prevent the side plate 14 from flipping downward and hindering the rotation of the column 5, a damping plate 17 is further provided at the hinge position of the side plate 14 and the seat frame 1 in this embodiment.

[0030] Furthermore, a limit plate 18 is symmetrically fixed in the seat frame 1. The limit plate 18 can make the side plate 14 flip to a vertical state when the side plate 14 flips downward, thereby ensuring that the fastening screw 15 can be aligned with the threaded hole 16, facilitating the screwing of the fastening screw 15.

[0031] Operation process: When the tooth-rolling plate 2 needs to be replaced, first screw the four fastening screws 15 on the side plate 14 to disengage the bolt ends from the threaded holes 16 on the column 5, and flip the side plate 14, then pull the pull ring 13 at one end of the seat frame 1, pull the brake block 11 out of the brake groove 12 of the disc 7, and rotate the knob 6 at the other end of the seat frame 1 until the required tooth-rolling plate 2 is rotated outside the seat frame 1, and finally release the pull ring 13. The brake block 11 can be reinserted into the brake groove 12 under the action of the spring 10, and finally reset the side plate 14, and screw a plurality of fastening screws 15 to reinsert them into the threaded holes 16 on the column 5, so as to replace the tooth-rolling plate 2.
