Description

Technical Field

[0001] This utility model relates to the field of gear running-in technology, specifically a gear running-in device. Background Technology

[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. Gears have been used in transmission for a long time and are one of the most widely used general-purpose parts in mechanical equipment. New gears, due to manufacturing precision issues, will experience relatively large wear if directly installed on mechanical equipment. The longer the saturation wear time, the shorter the normal wear time of the gear. To shorten the running-in and wear time, a break-in process is required before using the gear.

[0003] Existing gear break-in devices have the following drawbacks during use: the distance between the drive shaft and the driven shaft cannot be adjusted, making it difficult to apply to break-in of gears of different sizes; in addition, the debris generated during the break-in process adheres to the gears and can easily damage the gear surface. Therefore, there is room for improvement. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a gear running-in device, comprising: a main body mechanism and a circulation mechanism, wherein the main body mechanism comprises a box body, a lateral support fixed on one side of the box body, a fixed shaft mounted on the lateral support, a driven shaft slidably fitted on the lateral support, an adjusting rod mounted on one side of the lateral support and whose end is rotatably connected to the driven shaft, a motor fixed on one side of the lateral support and whose shaft is fixedly connected to the fixed shaft, and a protective cover hinged to the lateral support.

[0006] The circulation mechanism includes a filter screen fixed to the inner wall of the box, a spray component slidably installed on the top of the protective cover, and a pump fixed to one side of the box, with one end connected to the inner cavity of the box and the other end connected to the spray component.

[0007] In a preferred embodiment, the present invention can be further configured such that: the fixed shaft includes a first bearing symmetrically fixed on the inner wall of the lateral support and a first rotating shaft fixed on the inner ring of the first bearing, and the shaft of the motor is fixedly connected to the end of the first rotating shaft.

[0008] In a preferred embodiment, the present invention can be further configured such that: a rectangular hole is provided on one side of the lateral support, and the driven shaft includes a slider that is slidably fitted into the rectangular hole, a second bearing that is symmetrically fixed inside the slider, and a second rotating shaft fixed on the inner ring of the second bearing.

[0009] In a preferred embodiment, the present invention can be further configured such that: a threaded hole communicating with a rectangular hole is provided on one side of the lateral support, and the adjusting rod includes a threaded rod that passes through the threaded hole and is rotatably connected to the slider at one end, and a handwheel fixed to the other end of the threaded rod.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example

[0025] Combination Figure 1-5 As shown, this embodiment provides a gear running-in device, including: a main body mechanism 100 and a circulation mechanism 200.

[0026] The main body 100 includes a box body 110, a lateral support 120 fixed to one side of the box body 110, a fixed shaft 130 mounted on the lateral support 120, a driven shaft 140 slidably fitted on the lateral support 120, an adjusting rod 150 mounted on one side of the lateral support 120 and rotatably connected at its end to the driven shaft 140, a motor 160 fixed to one side of the lateral support 120 and fixedly connected to the fixed shaft 130, and a protective cover 170 hinged to the lateral support 120.

[0027] The housing 110 is used to install other components. The interior of the housing 110 is filled with lubricating oil for use by the circulation mechanism 200. The lateral support 120 is used to install the fixed shaft 130 and the driven shaft 140. The fixed shaft 130 includes a first bearing 131 symmetrically fixed on the inner wall of the lateral support 120 and a first rotating shaft 132 fixed on the inner ring of the first bearing 131. The first bearing 131 is used to fix the first rotating shaft 132 and ensure the stability of the first rotating shaft 132 when rotating. The first rotating shaft 132 is used to install gears and drive the gears to rotate. The shaft of the motor 160 is fixedly connected to the end of the first rotating shaft 132 to facilitate the motor 160 to drive the first rotating shaft 132 to rotate.

[0028] A rectangular hole 121 is provided on one side of the lateral support 120. The driven shaft 140 includes a slider 141 that is slidably fitted into the rectangular hole 121, a second bearing 142 that is symmetrically fixed inside the slider 141, and a second rotating shaft 143 that is fixed on the inner ring of the second bearing 142. The slider 141 is used to install the second bearing 142, the second bearing 142 is used to install the second rotating shaft 143, and the second rotating shaft 143 is used to place the gear that needs to be broken in. In addition, protrusions are fixed on both sides of the slider 141, and grooves are provided on the opposite inner walls of the rectangular hole 121. The protrusions are fitted into the grooves to ensure the stability of the slider 141 when it moves within the rectangular hole 121.

[0029] A threaded hole 122 is provided on one side of the lateral support 120, which communicates with a rectangular hole 121. The adjusting rod 150 includes a threaded rod 151 that passes through the threaded hole 122 and is rotatably connected to the slider 141 at one end, and a handwheel 152 fixed on the other end of the threaded rod 151. With this arrangement, when the handwheel 152 is turned, the threaded rod 151 is driven to rotate. The threaded rod 151 rotates in the threaded hole 122, causing the threaded rod 151 to move itself, which in turn drives the slider 141 to move. The movement of the slider 141 drives the second bearing 142 and the second rotating shaft 143 to move, thereby adjusting the distance between the first rotating shaft 132 and the second rotating shaft 143, which is convenient for running-in between different sizes.

[0030] The protective cover 170 is used to provide protection and prevent lubricating oil from splashing out. An observation window is provided on the protective cover 170 for the user to observe.

[0031] The circulation mechanism 200 includes a filter screen 210 fixed on the inner wall of the box 110, a spray component 220 slidably mounted on the top of the protective cover 170, and a pump 230 fixed on one side of the box 110 with one end communicating with the inner cavity of the box 110 and the other end communicating with the spray component 220.

[0032] The filter screen 210 can filter the lubricating oil falling into the box 110 and filter out the debris in the lubricating oil. The spray element 220 is used to wash away the debris on the gear. A through hole 171 is opened at the top of the protective cover 170. The spray element 220 includes a sliding seat 221 that is slidably fitted into the inner wall of the through hole 171 and a nozzle 222 installed at the bottom of the sliding seat 221. A groove is opened on the inner side wall of the through hole 171. Sliding strips are fixed on both sides of the sliding seat 221. The sliding strips are slidably fitted into the groove to ensure the stability of the sliding seat 221 when moving. The sliding seat 221 is used to install the nozzle 222 and drive the nozzle 222 to move. The nozzle 222 is used to spray out the lubricating oil.

[0033] The inlet of the pump 230 is connected to the inner cavity of the housing 110 through the liquid inlet pipe 231, which is used to extract the lubricating oil filtered by the filter screen 210 in the housing 110. The outlet of the pump 230 is connected to the nozzle 222 through the liquid outlet hose 232, which facilitates the pump 230 to pump the lubricating oil into the nozzle 222.

[0034] The working principle and usage process of this utility model are as follows: In use, one gear is installed on the first rotating shaft 132, and the other gear is installed on the second rotating shaft 143. Turning the handwheel 152 drives the threaded rod 151 to rotate. The threaded rod 151 rotates within the threaded hole 122, causing it to move, which in turn moves the slider 141. The movement of the slider 141 moves the second rotating shaft 143, causing the gear on the second rotating shaft 143 to mesh tightly with the gear on the first rotating shaft 132. Then, the motor 160 starts, driving the first... The rotating shaft 132 rotates, which drives the gears to rotate, and the gears are broken in. At the same time, the spray nozzle 220 is moved to a position above the meshing point of the two gears. The pump 230 is started, and the lubricating oil in the box 110 is drawn out through the inlet pipe 231 and pumped into the nozzle 222 through the outlet hose 232. The lubricating oil is sprayed out through the nozzle 222 to the meshing point of the two gears, which washes away the debris generated during the break-in. The lubricating oil containing debris falls into the box 110, is filtered by the filter screen 210, and is sent out again by the pump 230 to form a cycle.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
