Description

Technical Field

The box body and the box cover are combined to form a gear chamber, and the gear set is arranged in the gear chamber. Since the housing of the gearbox is an upper and lower split structure composed of the box body and the box cover, there are the following problems in using the traditional gearbox to carry out multiple sets of parameter comparison tests:

[0004] 1. If the gearbox as a whole is used as a test piece for the gear parameter comparison test, it is necessary to process several sets of gearboxes with different gear parameters. The test piece processing cycle is long and the test cost is high;

[0005] 2. If the gear is used as the test piece, it is necessary to replace the gear parts with different parameters to complete the comparative test. However, the upper and lower split structure of the traditional gear box makes it difficult to disassemble and assemble, and cannot meet the needs of frequent replacement of gear test pieces.

[0006] Therefore, in order to facilitate the replacement of test gears and reduce the cost of comparative tests, it is necessary to propose a gear box that can be quickly disassembled and assembled to achieve convenient and efficient replacement of gear test pieces in multiple groups of comparative tests.

A removable side panel 3 is fixed between the two vertical limit blocks 13. The removable side panel and the gearbox body 1 form a box body. Two limit columns 14 are provided on each vertical limit block 13. The gearbox body 1 is also provided with a plurality of side panel fixing mechanisms 16, and the side panel fixing mechanisms 16 fix the removable side panel 3 on the gearbox body 1. The top of the limit column 14 is provided with a chamfer, and the removable side panel 3 is provided with a limit hole that cooperates with the limit column 14. The removable side panel 3 can be quickly installed on the gearbox body 1 through the side panel fixing mechanism 16, and the removable side panel 3 can also be quickly disassembled and assembled, which is convenient for replacing the test gear 5 in the gearbox. The gearbox body 1 and the removable side panel 3 are provided with a shaft hole that cooperates with the working shaft 4.

[0048] The four sides of the box bottom plate 11 of the gear box body 1 are provided with horizontal extension edges 18, which are designed as a whole with the box bottom plate 11, and a plurality of bolt holes are provided on the horizontal extension edges 18 on each side. The horizontal extension edges 18 can be used with bolts to install the quickly detachable gear box in the horizontal direction, meeting the installation requirements of different quickly detachable gear boxes.

[0049] The gearbox that can be quickly disassembled and assembled in the present invention is a one-stage speed gearbox, and two test gears 5 are also included inside the gearbox body 1. The test gears 5 are respectively connected and installed with a working shaft 4. A bearing 6 is arranged between the test gear 5 and the rotating shaft hole. A bearing cover 7 is also arranged on the outside of the gearbox body 1. The bearing cover 7 is fixed to the gearbox body 1 by a plurality of bearing cover bolts 8. The gearbox body 1 is provided with threaded holes that cooperate with the bearing cover bolts 8. The bearing 6 can be a sliding bearing or a rolling bearing. The bearing 6 can adopt the existing technical method. The bearing cover 7 can fix the rolling bearing on the gearbox body 1, thereby facilitating the connection and installation of the test gear 5 and the working shaft 4.

[0050] like Figure 7As shown, the side panel fixing mechanism 16 is used to limit and fix the side of the removable side panel 3, so as to realize the installation and removal of the removable side panel 3, so that the test gear 5 can be quickly replaced. The side panel fixing mechanism 16 includes a fixing column 161, a hinge column 162, a pressure rod 163 and a second hinge end 164. One end of the fixing column 161 is provided with an open groove, the middle part of the pressure rod 163 is hinged in the open groove through the hinge column 162, and one end of the pressure rod 163 is hinged on the gear box body 1 through the second hinge end 164.

After the fixing through hole is connected with the fixing blind hole, the fixing column 161 is inserted into the removable side panel 3, thereby fixing the removable side panel 3. The locking principle of the side panel fixing mechanism 16 for the removable side panel 3 is specifically to press one end of the pressure rod 163. Under the action of the second hinged end 164, the middle pressure rod 163 drives the fixing column 161 to be inserted into the removable side panel 3 through the hinged column 162, thereby fixing the removable side panel 3. Finally, the movable box cover 2 is flipped and buckled on the gearbox body 1, and the box cover bayonet 17 is connected with the bayonet fixing mechanism 25, so as to realize the connection and fixation of the movable box cover 2 and the gearbox body 1. The connection method between the box cover bayonet 17 and the bayonet fixing mechanism 25 is similar to the principle of the anti-theft buckle.

[0051] like Figure 5 and 8As shown, an oil collecting port 111 is provided on the box bottom plate 11 of the gearbox body 1, and an oil storage mechanism 113 is provided on the oil collecting port 111. The oil storage mechanism 113 includes an oil storage cylinder 1131 which is sealed and connected to the oil collecting port 111, a piston 1132 is provided in the oil storage cylinder 1131, and the piston 1132 is connected to a piston rod 1133. A sealing plate 1134 is provided at the bottom of the oil storage cylinder 1131, and the piston rod 1133 penetrates through the sealing plate 1134 and is connected to the outside of the piston rod handle 1135. The oil storage mechanism 113 can store the lubricating oil in the gearbox body 1. When the test gear 5 is replaced, the lubricating oil in the gearbox body 1 can be temporarily stored and collected through the oil storage mechanism 113, so as to facilitate the replacement of the test gear 5. The box bottom plate 11 is also provided with a plurality of oil collecting grooves 112 connected with the oil collecting port 111. The oil collecting grooves 112 are evenly distributed on the outside of the oil collecting port 111. The oil collecting grooves 112 are inclined grooves with a high distal end and a low proximal end. The oil collecting grooves 112 can guide the lubricating oil in the gear box body 1 to the oil collecting port 111, so as to facilitate the transfer of the lubricating oil to the oil storage mechanism 113. The specific working principle of the oil storage mechanism 113 is that the piston rod handle 1135 is pulled externally, and the piston rod handle 1135 drives the piston rod 1133 and the piston 1132 to move, and the piston 1132 is used to collect the lubricating oil in the oil storage cylinder 1131. At the same time, the oil collecting grooves 112 can finally collect the flowing lubricating oil in the oil storage cylinder 1131, so that the disassembly, assembly and replacement of the test gear 5 are smoother.

[0052] like Fig. 9 and 10As shown, the bayonet fixing mechanism 25 includes a spring 251, a push plate 32 and a plurality of steel balls 254, which are arranged in the bayonet matching hole 22 from top to bottom, the top of the spring 251 is fixed to the bayonet matching hole 22 through the upper fixing plate 24, the upper fixing plate 24 is fixedly connected to the movable box cover 2, and the push plate 32 is provided with a bayonet hole 353 that matches the box cover bayonet 17, and the bayonet hole 353 is clearance-matched with the box cover bayonet 17. The bottom of the bayonet matching hole 22 is provided with an arc groove 23 that matches the steel ball 254, and the concave side of the arc groove 23 faces the steel ball 254. The movable box cover 2 is also provided with a strong magnet 28 that cooperates with the steel ball 254. The strong magnet 28 can be fixed on the movable box cover 2 by a chain or a rotatable rod. When the strong magnet 28 is needed to unlock the connection between the gear box body 1 and the movable box cover 2, it can be quickly taken, which greatly improves the disassembly and assembly efficiency of the gear box. Among them, the box cover latch 17 includes a latch body 171, a latch mounting hole is provided on the gear box body 1, the latch body 171 is fixed in the latch mounting hole, the latch body 171 is provided with an annular groove 172, and the top of the latch body 171 is provided with an arc top 173. The latch fixing mechanism 25 is the same as the principle of the traditional anti-theft buckle. Through the cooperation of the strong magnet 28, the steel ball 254, and the box cover latch 17, the gear box body 1 and the movable box cover 2 can be quickly connected. When the gear box needs to be opened, it is convenient to quickly open the movable box cover 2.

[0053] The top of the gearbox body 1 is provided with an oil filling hole, and an oil filling plug 26 is provided on the oil filling hole. The gearbox body 1 is connected to the movable case cover 2 through the first hinge end 21, and a circle of buckle frame 27 is provided on the movable case cover 2, and the inner frame of the buckle frame 27 is in contact with the outer wall of the gearbox body 1. The gearbox can be filled with oil at any time through the oil filling hole, and the oil filling plug 26 can be used to seal the oil filling hole conveniently.

[0054] The removable side panel 3 is provided with two matching limit blocks 31 that match with the vertical limit block 13. The vertical limit block 13 and the matching limit block 31 are provided with flush matching inclined surfaces 32. The oil filling plug 26 is provided on the oil filling hole to avoid the existence of corner seams, which can effectively improve the sealing between the removable side panel 3 and the gear box body 1. The lower side of the rectangular opening 12 is provided with a side panel mounting portion 15. The side panel mounting portion 15 and the gear box body 1 form an oil storage groove, so that lubricating oil can be stored. The side panel mounting portion 15 is provided with a strip sealing groove, and a circular sealing strip is provided in the strip sealing groove. The circular sealing strip is made of rubber and is bonded and fixed in the strip sealing groove. A groove that matches the circular sealing strip can also be provided at the bottom of the removable side panel 3, thereby further improving the sealing between the removable side panel 3 and the gear box body 1.

[0055] Example 2

[0056] like Figure 3 As shown, the difference between Example 2 and Example 1 is that the four sides of the box bottom plate 11 of the gear box body 1 are not provided with horizontal extension edges 18, but two vertical fixing plates 19 are provided on the outside of the gear box body 1, and the two vertical fixing plates 19 are designed as one piece with the gear box body 1, and a plurality of bolt holes are provided on each vertical fixing plate 19. The two vertical fixing plates 19 cooperate with the bolts to install the quickly detachable gear box in the vertical direction, so as to meet the installation requirements of different quickly detachable gear boxes.

[0057] Example 3

[0058] like Fig.11 As shown, the difference between Example 3 and Example 1 is that an oil storage baffle is provided on the inner side of the bottom of the gearbox body 1, and the oil storage baffle divides the interior of the gearbox body 1 into an upper working chamber and a lower oil storage chamber. A plurality of oil storage through holes are provided on the oil storage baffle, and the lubricating oil in the upper working chamber can flow into the lower oil storage chamber through the oil storage through holes. The oil storage mechanism 113 is provided at the side position of the gearbox body 1, and the diameter of the piston 1132 is smaller than the longitudinal depth of the lower oil storage chamber. When the oil storage capacity of the oil storage mechanism 113 is designed, at least the lubricating oil located above the oil storage baffle can be recovered and stored in the lower oil storage chamber. The oil storage mechanism 113 is provided at the side position of the gearbox body 1, which can avoid the interference between the oil storage mechanism 113 and the installation workbench, and facilitate the installation of the gearbox body 1.

[0059] Working process and principle:

[0060] When the gearbox can be quickly disassembled: first, the connection between the cover bayonet 17 and the bayonet fixing mechanism 25 is released by the magnetic force of the strong magnet 28. Specifically, the strong magnet 28 sucks the steel ball 254 out of the annular groove 172 of the bayonet body 171, thereby releasing the connection between the cover bayonet 17 and the bayonet fixing mechanism 25, and then the movable cover 2 is turned over to a horizontal position. Then, the lubricating oil in the gearbox body 1 is temporarily stored in the oil storage cylinder 1131 through the oil storage mechanism 113. The specific principle is similar to that of the syringe, and the lubricating oil is collected in the oil storage cylinder 1131 through the piston 1132. Then, several side panels of the removable side panel 3 can be unlocked by the side panel fixing mechanism 16, so that the fixing column 161 can be pulled out of the fixing blind hole of the removable side panel 3, so that the removable side panel 3 can be quickly removed. After the removable side panel 3 is removed, the exposed test gear 5 can be replaced. After the test gear 5 is replaced, the removable side panel 3 is installed first, and then the movable box cover 2 is closed. Finally, the temporarily stored lubricating oil in the oil storage cylinder 1131 of the oil storage mechanism 113 is pushed back into the gear box. The bearing 6 on the removable side plate 3 is generally fixed by the bearing cover 7 and the bearing cover bolt 8. When the removable side plate 3 is removed, the left inner wall of the gearbox body 1 and the right inner wall of the removable side plate 3 can be lifted by hydraulic equipment, so that the working shaft 4 is separated from the bearing 6 on the removable side plate 3, thereby facilitating the removal of the removable side plate 3; in order to further facilitate the removal of the bearing 6 and the working shaft 4 on the removable side plate 3, the inner ring of the bearing 6 can be plugged with the outside of the working shaft 4, in the form of a spline and a spline shaft, or in the form of a polygonal plug-in part, which can further facilitate the separation of the bearing 6 and the working shaft 4. In the process of removing the test gear 5 of the present invention, only the removable side plate 3 needs to be removed, the working shaft 4 and the gearbox body 1 remain fixed, one side of the test gear 5 is exposed, and the test gear 5 can be directly removed along the side of the removable side plate 3 on the working shaft 4. Compared with the traditional gearbox gear replacement method, the removal and replacement of gears is simpler and more efficient.

[0061] When installing the quickly disassembled gearbox: pass the working shaft 4 through the bearing hole of the left side plate of the gearbox body 1, and then fix the gearbox body 1 on the workbench or workbench frame, and then connect the test gear 5 to the working shaft 4 through a key. After the test gear 5 is installed and fixed, pass the working shaft 4 through the rotating shaft hole of the removable side panel 3, and install the removable side panel 3 on the rectangular opening 12, ensuring that the removable side panel 3 is aligned with the limit column, so that the inside of the removable side panel 3 is in contact with the vertical limit block 13, and then use the several side panel fixing mechanisms 16 on the side of the removable side panel 3 to fix the removable side panel 3, and finally flip the movable box cover 2, and fix it with the bayonet fixing mechanism 25 and the bayonet fixing mechanism 17.
