Technical Field
[0001] The utility model belongs to the field of gear inspection, in particular to a simple gear box inspection device. Background Art
[0002] Gearboxes are important components widely used in mechanical transmissions. Gearboxes must be inspected before they are put into use. The inspection serves two purposes: first, to test the noise and temperature during operation; these noise and temperature can reflect the meshing impact of the gears. For example, when a pair of gears mesh, meshing impact is inevitable due to errors in tooth pitch and tooth profile, which in turn generates noise corresponding to the gear meshing frequency. Frictional noise and a certain temperature are also generated due to relative sliding between the tooth surfaces. The lower the noise and temperature, the smaller the gear meshing impact and the higher the accuracy. Second, to test whether the gearbox is leaking oil during operation.
[0003] The traditional method is to manually rotate the gearbox to be inspected, which is inefficient and has low detection accuracy. Utility Model Content
[0004] In order to solve the above deficiencies in the prior art, the present invention aims to provide a simple gearbox inspection device to realize automatic rotation of the gearbox and complete the inspection of gearbox noise, temperature and leakage.

DETAILED DESCRIPTION
[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and do not constitute a limitation to the present invention.
[0024] like Figures 1 to 4 As shown, this embodiment includes a frame 1, a power member fixed on the frame 1, a rotating member 3 rotatably arranged on the frame 1, and an oil supply assembly; the power member and the rotating member 3 are used to realize the automatic rotation of the gear box 11; the oil supply assembly is used to supply oil to the gear box 11 to check whether the gear box 11 leaks oil when it runs at high speed.
[0025] like Figure 1 As shown, the power member is fixed inside the frame 1. In this embodiment, the power member adopts the motor 2 in the prior art, and the motor 2 is fixed on the bottom plate 101 of the frame 1. Of course, the power member can also be replaced with any other device in the prior art that can provide rotational driving force.
[0026] like Figure 3 As shown, the rotating member 3 includes a rotary shaft 31 and a transmission shaft 32. The input end of the transmission shaft 32 is fixedly connected to the output end of the rotary shaft 31. The output end of the rotating member 3 is used to be fixedly connected to the input shaft of the gear box 11. The output end of the rotating member 3 here refers to the output end of the transmission shaft 32, that is, the end of the transmission shaft 32 away from the rotary shaft 31. The output end of the transmission shaft 32 is fixedly connected to the input shaft of the gear box 11. The transmission shaft 32 adopts the existing technology. A support platform 5 is provided on the frame 1, and the gear box 11 is fixed on the support platform 5. Figure 4Because the distance between the rotating shaft 31 and the gearbox 11 is relatively long, if only a straight rod is used, with its ends connected to the output end of the rotating shaft 31 and the input shaft of the gearbox 11, then when the gearbox 11 is not being inspected, the end of the straight rod away from the rotating shaft 31 will sink due to gravity, causing damage to the straight rod over time. The drive shaft 32 is equipped with a universal joint. When the gearbox 11 is not being inspected, the end of the drive shaft 32 away from the rotating shaft 31 will overlap the frame 1. A support plate for supporting the drive shaft 32 is provided on the frame 1 at the position corresponding to the drive shaft 32.
[0027] In this embodiment, one end of the transmission shaft 32 connected to the gear box 11 is provided with a T-shaped spline, and the transmission shaft 32 is key-connected to the input shaft of the gear box 11 .
[0028] The input end of the rotating member 3 is connected to the output end of the power member, that is, the input end of the rotary shaft 31 is connected to the output end of the power member. In this embodiment, a transmission member is further provided between the power member and the rotating member 3, such as Figure 1 As shown, the input end of the transmission member is connected to the output end of the power member, and the output end of the transmission member is connected to the input end of the rotating member 3. The transmission member includes a belt 6, a first pulley 7 and a second pulley 8. The first pulley 7 is the input end of the transmission member and is fixedly connected to the output end of the power member. The second pulley 8 is the output end of the transmission member and is fixedly connected to the input end of the rotating member 3. That is, the second pulley 8 is fixedly connected to the end of the rotating shaft 31 away from the transmission shaft 32. The belt 6 is sleeved on the first pulley 7 and the second pulley 8.
[0029] Of course, in this embodiment, the motor 2 can also be used to directly drive the rotating member 3 to rotate. The motor 2 is fixed to the upper surface of the frame 1, and the output shaft of the motor 2 is fixedly connected to the end of the rotary shaft 31 away from the transmission shaft 32.
[0030] like Figure 1 As shown, the frame 1 is also provided with an electronic controller 9 for controlling the output speed of the motor 2. The electronic controller 9 is electrically connected to the power member. The electronic controller 9 adopts the existing technology and will not be described in detail in this embodiment.
[0031] The oil supply assembly is used to supply oil to the gear box 11, and the oil delivery end of the oil supply assembly is connected to the oil inlet of the gear box 11. Specifically, Figure 1 As shown, the oil supply assembly includes an oil tank 4 arranged inside the frame 1 and an oil pump arranged in the oil tank 4. The setting position of the oil tank 4 can save space. The oil pump is connected to the oil inlet of the gear box 11 through an oil pipe. The end of the oil pipe away from the oil tank 4 is the oil delivery end of the oil supply assembly. Figure 1-4 The oil pipelines are not shown.
[0032] In this embodiment, the oil is pumped into the gear box 11 by an oil pump. Of course, any other structure in the prior art can also be used as long as it can supply oil to the gear box 11.
[0033] Since the rotating member 3 rotates at high speed when the gear box 11 is inspected, in order to prevent the rotating member 3 from flying out, Figure 1-3 As shown, a protective cover 10 is provided on the frame 1 at a position corresponding to the rotating member 3. In this embodiment, the rotary shaft 31 is rotatably provided on the frame 1. Specifically, a bearing sleeve 12 is provided on the outer sleeve of the rotary shaft 31. Figure 3 The bearing sleeve 12 is fixed on the fixing seat 13, and the fixing seat 13 is fixed on the frame 1. The rotary shaft 31 passes through the bearing sleeve 12 and is rotatably connected to the bearing sleeve 12. The bearing sleeve 12 is a prior art and will not be described in detail here. Preventing the rotating member 3 from flying out here means preventing the transmission shaft 32 from separating from the rotary shaft 31 and flying out when rotating at high speed. In this embodiment, the longitudinal section of the protective cover 10 is an isosceles trapezoid, as shown in FIG. Figure 2 As shown, an interception space 14 is formed between the protective cover 10 and the frame 1 , and the transmission shaft 32 in the rotating member 3 is located in the interception space 14 .
[0034] When using this embodiment, if Figure 4 As shown, motor 2 starts, driving belt 6, which in turn drives rotating shaft 31 and drive shaft 32, rotating the gears within gearbox 11. This device achieves automated rotation of the gears within gearbox 11. Electronic controller 9 controls the speed of motor 2, achieving high-speed operation of the gears. While the gears are operating, a decibel meter can be used to detect noise outside gearbox 11, and a thermometer can be used to measure the surface temperature of gearbox 11. The oil supply assembly pumps oil into gearbox 11, and during high-speed operation, the surface of gearbox 11 is observed for oil seepage, thereby verifying whether the gearbox 11 is leaking.
[0035] In this embodiment, the gears can also be tested for running-in by supplying oil to the gear box 11. After the inspection is completed, the oil is discharged through the discharge port on the gear box 11. The oil will carry out the dirt on the gears and flow into the oil tank 4. After the dirt is settled in the oil tank 4, the clean oil at the top of the oil tank 4 is pumped into the gear box 11 again for inspection.
[0036] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may still modify the technical solutions described in the above embodiments or replace some of the technical features therein with equivalents.
