Description

Technical Field

[0001] This utility model relates to the field of gearbox shaft alignment quality inspection technology, and more specifically, to gearbox shaft alignment tooling. Background Technology

[0002] The gearbox shaft system includes the input shaft, intermediate shaft, output shaft, and reverse shaft. Currently, before assembling the gearbox shaft system into the housing, a gear meshing process is required on the main shaft and the countershaft. The necessity and technical function of gear meshing are as follows:

[0003] (1) Ensure gear accuracy and fit;

[0004] (2) Eliminate gear backlash;

[0005] (3) Balanced load distribution;

[0006] (4) Extend the life of the transmission;

[0007] (5) Adaptable to complex working conditions;

[0008] The current gearbox shaft alignment process requires the use of multiple bolts and clamping components to define the positions of the main shaft and the auxiliary shaft. Then, the auxiliary shaft is manually moved close to the main shaft to mark the gears and complete the gear alignment quality inspection process. As a result, the gear alignment process is not convenient enough, and the gear alignment quality inspection procedure for the gearbox shaft needs to be improved. Utility Model Content

[0009] The purpose of this utility model is to solve the problems mentioned in the background art, and then to propose a gearbox shaft gearing fixture.

[0010] The technical solution adopted by this utility model to solve its technical problem is:

[0011] The gearbox shaft alignment fixture includes a mounting bracket, a base plate, a mounting disc, a countershaft placement cylinder, a main shaft placement cylinder, a stepped groove, a sliding limit assembly, a through hole, a first limit flange, a second limit flange, and a third limit flange.

[0012] The base plate is fixed to the mounting frame;

[0013] The spindle placement cylinder is fixed in the center of the base plate, and the spindle placement cylinder is provided with a stepped groove that penetrates the base plate and partially abuts against the circumference of the spindle.

[0014] The sliding limit components are symmetrically arranged on the base plate;

[0015] The mounting plate is fixedly connected to the sliding limit component, and a through hole is provided on the mounting plate;

[0016] The auxiliary shaft placement cylinder is fixed on the mounting plate and the auxiliary shaft placement cylinder is concentric with the through hole;

[0017] The first limiting flange, the second limiting flange, and the third limiting flange are formed circumferentially from top to bottom inside the secondary shaft placement cylinder and circumferentially abut against the secondary shaft at three different height positions. The distance between the inner wall of the first limiting flange, the second limiting flange, and the third limiting flange and the central axis of the secondary shaft placement cylinder decreases sequentially.

[0018] Furthermore, the sliding limit assembly includes a slide rail, a slider, a limit pin, a threaded cylinder, and a long screw.

[0019] The slide rails are symmetrically fixed on the base plate, and the slide rails are slidably fitted with sliders that are fixed to the mounting plate.

[0020] The limiting pins are fixed on the base plate and are symmetrically distributed about the slide rail, respectively contacting the front and rear ends of the slider;

[0021] The threaded cylinder is fixed to the base plate and positioned between two slide rails;

[0022] The long screw passes through the mounting hole on the mounting plate and is threaded into the threaded cylinder.

[0023] Furthermore, a knob is provided at the end of the long screw away from the threaded cylinder.

[0024] Furthermore, the base plate is symmetrically provided with handles, and the surface of the handles is formed with several arc grooves.

[0025] Furthermore, the surfaces of the stepped groove, the first limiting flange, the second limiting flange, and the third limiting flange are respectively provided with a rubber layer.

[0026] Furthermore, the mounting plate and the sub-shaft placement cylinder are connected by an arc-shaped extension plate.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

The gear alignment process of the main shaft gear and the secondary shaft gear is more convenient, resulting in better quality inspection of the gear alignment of the gearbox shaft system.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0035] like Figures 1 to 3 As shown, the gearbox shaft alignment fixture includes a mounting bracket 1, a base plate 2, a mounting disc 6, a countershaft placement cylinder 9, a main shaft placement cylinder 10, a stepped groove 11, a sliding limit assembly, a through hole, a first limit flange 12, a second limit flange 13, and a third limit flange 14.

[0036] The base plate 2 is fixed on the mounting bracket 1;

[0037] The spindle placement cylinder 10 is fixed in the center of the base plate 2, and the spindle placement cylinder 10 is provided with a stepped groove 11 that penetrates the base plate 2 and partially abuts against the circumference of the spindle.

[0038] The sliding limit components are symmetrically arranged on the base plate 2;

[0039] The mounting plate 6 is fixedly connected to the sliding limit component, and the mounting plate 6 has a through hole (the through hole is shown in the figure but not labeled);

[0040] The secondary shaft placement cylinder 9 is fixed on the mounting plate 6 and the secondary shaft placement cylinder 9 is concentric with the through hole (specifically, the mounting plate 6 and the secondary shaft placement cylinder 9 are connected by an arc-shaped extension plate (the arc-shaped extension plate is shown in the figure but is not labeled). The function of the arc-shaped extension plate is to facilitate the bolt connection between the mounting plate 6 and the slider 4, and to ensure that the gears to be aligned are at the same height after the main shaft and secondary shaft are placed).

[0041] The first limiting flange 12, the second limiting flange 13, and the third limiting flange 14 are formed circumferentially from top to bottom inside the secondary shaft placement cylinder 9 and circumferentially abut against the secondary shaft at three different height positions. The distance between the inner wall of the first limiting flange 12, the second limiting flange 13, and the third limiting flange 14 and the central axis of the secondary shaft placement cylinder 9 decreases sequentially.

[0042] Specific implementation of the embodiments of this utility model, such as Figures 1 to 3 As shown, the sliding limit assembly includes a slide rail 3, a slider 4, a limit pin 5, a threaded cylinder 7, and a long screw 8.

[0043] The slide rail 3 is symmetrically fixed on the base plate 2, and the slide rail 3 has a slider 4 that is fixedly connected to the mounting plate 6.

[0044] The limiting pins 5 are fixed on the base plate 2 and are symmetrically distributed about the slide rail 3, respectively abutting against the front and rear ends of the slider 4;

[0045] The threaded cylinder 7 is fixed on the base plate 2 and is located between the two slide rails 3;

[0046] The long screw 8 passes through the mounting hole on the mounting plate 6 and is threaded to the threaded cylinder 7 (the mounting hole is shown in the figure but is not numbered).

[0047] To facilitate the operation of the long screw 8, a further optimization of the above embodiment is provided: a knob (the knob is shown in the figure but not labeled) is provided at the end of the long screw 8 away from the threaded cylinder 7.

[0048] To facilitate the disassembly and transfer of the base plate 2, the above embodiment is further optimized by providing symmetrical handles 21 on the base plate 2, and the surface of the handles 21 is formed with several arc grooves, which are shown in the figure but not labeled.

[0049] In order to reduce the probability of wear during the contact between the main shaft placement cylinder 10 and the secondary shaft placement cylinder 9 with the main shaft and the secondary shaft respectively, the surfaces of the stepped groove 11, the first limiting flange 12, the second limiting flange 13 and the third limiting flange 14 are respectively provided with rubber layers, which are not shown in the figure.

[0050] The working process of this utility model is as follows:

[0051] First, the main spindle is placed upright in the main spindle placement cylinder 10. At this time, the stepped groove 11 can abut against the corresponding area of ​​the main spindle to limit its position. Meanwhile, the end of the main spindle extends below the base plate 2. After the main spindle is placed, the two secondary spindles are placed upright in the two secondary spindle placement cylinders 9 one after the other. At this time, the first limiting flange 12, the second limiting flange 13, and the third limiting flange 14 abut against the corresponding areas of the secondary spindle, thereby limiting the position of the secondary spindle (after the position of the secondary spindle is limited, its end passes through the through hole but does not contact the base plate). (It should be noted that the main spindle and the secondary spindle are relatively heavy, so the position is not easy to shift after the abutment and limiting).

[0052] After the main spindle and secondary spindle are positioned and limited, first rotate the long screw 8 by turning the knob to disengage it from the threaded cylinder 7, thus releasing the lock. Then, grasp the mounting plate 6 to push the slider 4 along the slide rail 3 (the limiting pin 5 limits the two ends of the slider 4's movement along the slide rail 3). Then, the two secondary spindle placement cylinders 9, together with the secondary spindle, approach the main spindle placement cylinder 10 from both sides. The meshing status of the main spindle gear and the secondary spindle gear can then be marked. If it is qualified, the main spindle placement cylinder 10 and the secondary spindle placement cylinder 9 are reset sequentially (as per the instruction manual). Figure 1 (as shown in the image), then remove the spindle and sub-spindle.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
