Description

Technical Field

[0001] The utility model relates to the technical field of transmission maintenance, and in particular to a transmission main and secondary shaft support base. Background Art

[0002] When disassembling and overhauling the transmission, the disassembled parts need to be properly stored and kept. Among them, the main and secondary shafts of the transmission need to be placed on designated supporting components because of their sophisticated and complex structures. This not only ensures that the main and secondary shafts can be supported, but also facilitates the overhaul of gears, bearings and other components above the main and secondary shafts.

[0003] However, since the models and specifications of the main and secondary shafts of different transmissions are different, the models of the supporting components cannot be adjusted randomly. This will result in inadequate support or interference between the main and secondary shafts during maintenance. Utility Model Content

[0004] The utility model provides a transmission main and secondary shaft support base, which can support the main and secondary shafts and change the distance between them by moving the secondary shaft support sleeve, so as to accommodate main and secondary shafts of more specifications and ensure that the two do not interfere with each other during maintenance.

[0005] To this end, the technical solutions adopted are as follows:

[0006] A transmission main and secondary shaft support base comprises a support base plate and a main shaft support sleeve and a secondary shaft support sleeve for placing the main shaft and the secondary shaft respectively; the main shaft support sleeve is fixedly connected to the support base plate, and the secondary shaft support sleeve is connected to the support base plate via a sliding mechanism.

[0007] A further technical solution is that the main shaft support sleeve is a vertically arranged cylindrical structure, and the secondary shaft support sleeve includes a bearing sleeve and a secondary shaft sleeve arranged up and down, and the bearing sleeve and the secondary shaft sleeve are both vertically arranged cylindrical structures and are coaxially fixed.

[0008] A further technical solution is that the sliding mechanism includes a slide rail and a slider matching the slide rail, the slide rail is fixed on the supporting base plate, the secondary shaft support sleeve is fixed on the slider and can gradually approach or move away from the main shaft support sleeve along the slide rail.

[0009] A further technical solution is that the sliding mechanism is composed of two groups arranged in parallel, a horizontally arranged support plate is fixed to the bottom of the secondary shaft support sleeve, and the support plate is fixed together with the two groups of sliding blocks.

[0010] A further technical solution is that limiting rods are fixed at both ends of the slide rail, and the two limiting rods respectively abut against the slide block when the slide block moves to the two ends of the slide rail.

[0011] A further technical solution is that a locking bolt is vertically penetrated through the support plate, and the locking bolt can contact or leave the upper surface of the support base plate by rotating.

[0012] A further technical solution is that an anti-slip sleeve is fixedly mounted on the bottom of the locking bolt.

[0013] A further technical solution is that the spindle support sleeve and the support base plate are detachably fixed.

[0014] A further technical solution is that lifting handles are fixed to both ends of the supporting base plate.

[0015] The working principle and beneficial effects of this application are:

[0016] 1. The countershaft support sleeve can be moved through the sliding mechanism to adjust the position of the countershaft support sleeve, and the distance between the main and countershafts can be adjusted to ensure that no interference occurs during maintenance.

[0017] 2. The spindle support sleeve and the support base plate are detachable, so that different spindle support sleeves can be replaced to support spindles of different specifications. The disassembly and assembly are simple, and there is no need to replace the entire support base, which is convenient and quick.

[0018] 3. The main shaft support sleeve and the secondary shaft support sleeve are divided into two parts, so as to meet the independent support of the main shaft and the secondary shaft. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-Figure 5 As shown, a transmission main and secondary shaft support base includes a support base plate 1 and a main shaft support sleeve 2 and a secondary shaft support sleeve 3 for placing the main shaft 20 and the secondary shaft 30 respectively; the main shaft support sleeve 2 is fixedly connected to the support base plate 1, and the secondary shaft support sleeve 3 is connected to the support base plate 1 through a sliding mechanism 4.

[0028] Thus, the secondary shaft support sleeve 3 can be moved by the sliding mechanism 4 to adjust the position of the secondary shaft support sleeve 3, and further adjust the distance between the main shaft and the secondary shaft 30 to ensure that there is no interference during maintenance. The main shaft support sleeve 2 and the secondary shaft support sleeve 3 are divided into two parts, so that the main shaft 20 and the secondary shaft 30 can be supported separately. In addition, the main shaft support sleeve 2 and the support base plate 1 are detachably fixed, so that different specifications of the main shaft 20 can be supported by replacing different main shaft support sleeves 2. It is fixed by bolts, and the disassembly and assembly are simple, and there is no need to replace the entire support base. The whole process is convenient and fast.

[0029] like Figure 3 As shown, the main shaft support sleeve 2 is a vertically arranged cylindrical structure, and the secondary shaft support sleeve 3 includes a bearing sleeve 31 and a secondary shaft sleeve 32 arranged up and down, and the bearing sleeve 31 and the secondary shaft sleeve 32 are both vertically arranged cylindrical structures and coaxially fixed. The sliding mechanism 4 includes a slide rail 41 and a slider 42 matched with the slide rail 41, the slide rail 41 is fixed on the support base plate 1, and the secondary shaft support sleeve 3 is fixed on the slider 42 and can gradually approach or move away from the main shaft support sleeve 2 along the slide rail 41.

[0030] The support base is used to hoist the main shaft 20 and the secondary shaft 30. Figure 4-Figure 5 As shown, it is in a vertical state and is placed in the main shaft support sleeve 2 and the secondary shaft support sleeve 3 respectively. It can also prevent the main shaft 20 or the secondary shaft 30 from being supported separately. When the distance between the main shaft 20 and the secondary shaft 30 is too large or too small to be convenient for maintenance, the secondary shaft support sleeve 3 is pushed, and the slider 42 slides on the slide rail 41, thereby adjusting the position of the secondary shaft 30 and changing the distance between the main shaft 20 and the secondary shaft 30.

[0031] Among them, in order to ensure that the sliding mechanism 4 runs smoothly and smoothly, the sliding mechanism 4 is arranged in two parallel groups, and a horizontally arranged support plate 43 is fixed at the bottom of the secondary shaft support sleeve 3, and the support plate 43 is fixed together with the two groups of sliders 42. The support plate 43 is fixed on the two sliders 42. When the secondary shaft 30 is placed in the secondary shaft support sleeve 3, the force is more uniform and stable.

[0032] In addition, limit rods 44 are fixed at both ends of the slide rail 41. The two limit rods 44 respectively abut against the slider 42 when the slider 42 runs to the two ends of the slide rail 41. Therefore, when the slider 42 runs to the extreme positions at both ends of the slide rail 41, it will be blocked by the limit rods 44 to prevent the slider 42 from falling out.

[0033] like Figure 1 As shown, a locking bolt 45 is vertically penetrated on the support plate 43, and the locking bolt 45 can contact or leave the upper surface of the support base plate 1 by rotating, so that when the secondary shaft support sleeve 3 slides to a suitable position, the locking bolt 45 can be rotated to make it abut against the support base plate 1, thereby locking the support plate 43 with the support base plate 1, that is, fixing the secondary shaft support sleeve 3 to prevent the secondary shaft 30 from moving during the inspection process. In addition, an anti-slip sleeve 451 is fixed to the bottom of the locking bolt 45, and the material of the anti-slip sleeve 451 can be polyurethane, which can increase the friction with the support base plate 1, ensure a more stable locking, and prevent the rigid material locking bolt 45 from directly contacting the support base plate 1 to cause wear.

[0034] In addition, lifting handles 5 are fixed at both ends of the support base plate 1, and the entire support base can be conveniently moved to a specified position through the lifting handles 5, so as to adapt to the disassembly and assembly of the main and secondary shafts 30 of the transmission in various occasions.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
