Description

  The present invention relates to the improvement of the structure of the gear box, and the gear assembly is composed of a fixed cover piece, a drive gear, a reduction gear, a transmission gear, and a reverse claw. Further, the present invention relates to a gear box in which a gear assembly can be made into a single-molded form by fitting a fixed cover piece, and a user can exchange the gear assembly more conveniently.

  Since a conventional conventional gearbox is not provided with a fixed cover piece in its gear assembly, when the user replaces the gear, the drive gear, reduction gear, transmission gear and reverse claw are removed and attached. After the user removes the gear, the drive gear, the reduction gear, the transmission gear, and the reverse claw cannot be distinguished from each other. When it is incorporated into the shell body, it must be individually incorporated into the shell body, so that it is easy to confuse the user and is inconvenient to assemble.

  For this reason, how to eliminate the above-mentioned problem is a technical problem to be solved by the present invention.

  An object of the present invention is to provide a gear box in which a gear assembly is modularized and can be exchanged conveniently by a user.

  Hereinafter, the present invention will be described in detail based on the drawings, reference numerals, and embodiments. The structure improvement of the gear box of the present invention is mainly composed of a fixed cover piece F and a gear assembly A as shown in FIGS.

  The gear assembly A includes a fixed cover piece F, a driving gear B, a reduction gear C, a transmission gear D, and a reverse claw E, and the fixed cover pieces F corresponding to each other are fitted on both sides of the gear assembly A. Of these, a first shaft hole F1, a second shaft hole F2, a third shaft hole F3 and a fourth shaft hole F4 corresponding to the gear assembly A are provided on the fixed cover piece F.

  The first shaft hole F1 of the fixed cover piece F is fitted to the first shaft rod B4 of the drive gear B, and the second shaft hole F2 of the fixed cover piece F is fitted to the second shaft rod C3. The third shaft hole F3 of the fixed cover piece F is fitted to the third shaft rod D3 of the transmission gear D, and the fourth shaft hole F4 of the fixed cover piece F is connected to the shaft rod E1 of the reverse claw E. They are mated together.

  Further, the rack B3 of the drive gear B moves in mesh with the reverse claw E, and the small gear B2 of the drive gear B moves in mesh with the first reduction gear C1 of the reduction gear C, and decelerates. The second reduction gear C2 of the gear C moves while meshing with the entire peripheral teeth D1 of the transmission gear D.

In order to show the inventiveness and practicality of the present invention more clearly, the following analysis is made in comparison with the conventional product.
《Disadvantages of conventional products》
1.
Since no fixed cover piece is provided, the gears must be removed individually when changing gears.
2.
The first point is likely to cause confusion for the user.
3.
The first point is inconvenient to assemble.
<Advantages of the present invention>
1.
The gear assembly is provided with a fixed cover piece, and the internal gear takes the form of an integral molding.
2.
In response to the first point, it is only necessary to directly remove and incorporate the gear assembly for replacement.
3.
The fixed cover piece is low in cost and convenient for exchanging the gear assembly.
Four.
Inventive and practical.
Five.
Improve industrial competitiveness.

  The implementation of the present invention provides an improved gear box structure, and as shown in FIGS. 2, 3, 4 and 5, the gear assembly A includes fixed cover pieces F symmetrical to each other, Among them, the fixed cover piece F of the gear assembly A is provided with a first shaft hole F1, a second shaft hole F2, a third shaft hole F3, and a fourth shaft hole F4, and the first shaft hole of the fixed cover piece F is provided. F1, the second shaft hole F2, the third shaft hole F3 and the fourth shaft hole F4 correspond to the first shaft rod B4, the second shaft rod C3, the third shaft rod D3 and the shaft rod E1 of the gear assembly A, respectively. The drive gear B, the reduction gear C, the transmission gear D, and the reverse claw E are tightly fitted by the mutually symmetrical fixed cover pieces F, so that the gear assembly A becomes an integral molding mode and is symmetrical with each other. The fixed cover pieces F are fitted to each other by a fixed bar F5.

  When the user wants to replace the gear assembly A, it is only necessary to remove the gear assembly A, and when the gear assembly A is mounted in the shell body G, the gear assembly A is fitted to the shell body G. If the rack gear B1 of the drive gear B and the bevel gear I of the shell body G are meshed with each other, and the partial teeth D2 of the transmission gear D and the sliding rack H1 of the piston cylinder H are meshed with each other, the gear assembly A can be smoothly moved. It can be installed in the shell body G, and the design of the gear assembly A allows the user to remove and install the gear assembly A more conveniently.

  When the motor J of the shell body G rotates, the bevel gear I on the motor J rotates simultaneously. At this time, the bevel gear I drives the drive gear B of the gear assembly A, of which the drive gear B of the gear assembly A is driven. Simultaneously, the reduction gear C of the gear assembly A is rotated. When the reduction gear C of the gear assembly A is rotated, the transmission gear D of the gear assembly A is driven. At this time, the transmission gear D of the gear assembly A is driven. However, the sliding rack H1 of the piston cylinder H is driven by the partial tooth D2 of the transmission gear D, and the piston cylinder H is operated.

  The above description is based on the best embodiment of the present invention, and does not limit the patent scope of the present invention. The structure for obtaining the equivalent effect based on the contents of the specification and drawings of the present invention is directly described. Anything indirectly applied to other related technical fields is considered to be within the scope of the gist of the present invention.

  As described above, the present invention can achieve the effect of surely improving the structure under a structure that breaks down the prior art, and is not easily conceived by those who are familiar with related technologies. The invention has never been published before its application, and its inventive step and practicality satisfy the requirements for a utility model registration application.
