Description

Technical Field

[0001] The utility model relates to the technical field of gear boxes, in particular to a gear box with convenient heat dissipation. Background Art

[0002] A gearbox is a mechanical transmission device that converts the high-speed rotation of a motor into a low-speed, high-torque output. A gearbox typically consists of an input shaft, an output shaft, a gear train, bearings, and seals. When the motor rotates the input shaft, the gears on the input shaft mesh with each other, driving the gear train on the output shaft, thereby rotating the output shaft.

[0003] A large amount of lubricant is added to the gearbox chassis to reduce friction between the gear contact surfaces. This generates heat during operation, and the longer the gearbox operates, the more heat it generates. Because the gearbox chassis is enclosed, its heat dissipation performance is poor, making it difficult to dissipate heat from within the chassis. Over time, this can damage the gears and shorten the gearbox's service life. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] like Figure 1-3 As shown, the utility model discloses a gearbox with convenient heat dissipation, including a base plate 1, a chassis 2 fixedly arranged above the base plate 1, a heat dissipation component is provided above the base plate 1, the heat dissipation component includes an oil tank 3 fixedly arranged above the base plate 1, a pump A4 and a pump B5 fixedly arranged above the base plate 1, an oil inlet pipe A6 and an oil inlet pipe B7, an oil outlet pipe A8 and an oil outlet pipe B9, and a control component, the pump A4 and the pump B5 are both connected to the control component, the two ends of the oil inlet pipe A6 are respectively connected to the oil inlet end of the pump A4 and the interior of the chassis 2, the two ends of the oil outlet pipe A8 are respectively connected to the oil outlet end of the pump A4 and the interior of the oil tank 3, the two ends of the oil inlet pipe B7 are respectively connected to the oil inlet end of the pump B5 and the interior of the oil tank 3, and the two ends of the oil outlet pipe B9 are respectively connected to the oil outlet end of the pump B5 and the interior of the chassis 2. When the present invention is used, lubricating oil is poured into the chassis 2 and the oil tank 3, and the thermometer 10, the fan 12, the pump A4 and the pump B5 are connected to the controller 11; when the gear box has been working for a long time and the temperature inside the chassis 2 rises, the thermometer 10 will detect it and transmit the signal to the controller 11, and the controller 11 will control the pumps A4 and B5 to start, and the lubricating oil inside the chassis 2 will be sucked out by the pump A4, and enter the oil tank 3 after passing through the oil inlet pipe A6, the pump A4, and the oil outlet pipe A8. The lubricating oil inside the oil tank 3 will be sucked out by the pump B5, and enter the chassis 2 after passing through the oil inlet pipe B7, the pump B5, and the oil outlet pipe B9, so that the hot oil inside the chassis 2 is mixed with the cold oil inside the oil tank 3. The interchange can quickly reduce the internal temperature of the chassis 2, which facilitates heat dissipation; after the internal temperature of the chassis 2 drops, the pump A4 and the pump B5 are turned off, and the interchange of the lubricating oil is stopped. The internal temperature of the oil tank 3 filled with hot oil will rise, and the oil tank 3 will transfer the heat to the heat sink 13, and the fan 12 is started to dissipate heat to the heat sink 13, so that the temperature of the oil tank 3 and the lubricating oil inside it are reduced, and preparations are made for subsequent interchanges; in summary, the present invention has the beneficial effect of convenient heat dissipation, and solves the problem that the gear box chassis 2 is closed and has poor heat dissipation performance, which makes it inconvenient to dissipate heat inside the chassis 2. If things go on like this, the gears will be damaged, which affects the service life of the gear box.

[0019] Preferably, the control assembly includes a thermometer 10 fixed to the chassis 2 and a controller 11 fixed to the baseplate 1. The thermometer 10 is connected to the controller 11 via wires, and the controller 11 is connected to pumps A4 and B5 via wires. Since the controller 11 is connected to pumps A4 and B5 via wires, it facilitates the on / off control of pumps A4 and B5. (The functions implemented by the hardware in this utility model are supported by a wealth of mature technologies. The essence of this utility model lies in its specific application. The aforementioned connection and control methods are all existing technologies and do not involve modifications to the hardware's internal software.)

[0020] Preferably, the heat dissipation assembly further includes a fan 12 and a plurality of heat sinks 13 fixedly disposed on the front and rear sides of the chassis 2. The fan 12 is located directly above the heat sink 13 and is connected to the controller 11 via a wire. Since the fan 12 is located directly above the heat sink 13 and is connected to the controller 11 via a wire, starting the fan 12 dissipates heat from the heat sink 13, thereby achieving a rapid heat dissipation effect.

[0021] Preferably, the heat dissipation assembly further includes an oil pouring pipe 14 and a cover 15 fixedly mounted above the oil tank 3. The outer side of the oil pouring pipe 14 and the inner side of the cover 15 are both threaded, and the oil pouring pipe 14 and the cover 15 are threadedly fixedly connected. The fixed installation of the oil pouring pipe 14 above the oil tank 3 facilitates the addition of new oil.

[0022] Preferably, a filter screen 16 is fixedly provided inside the oil tank 3, and the filter screen 16 is located below the connection between the oil outlet pipe A8 and the oil tank 3. Since the filter screen 16 is located below the connection between the oil outlet pipe A8 and the oil tank 3, it plays a role in filtering impurities inside the lubricating oil.

[0023] Preferably, a bottom pad 17 is fixedly provided below the bottom plate 1, and the bottom pad 17 is a rubber pad. Since the bottom pad 17 is fixedly provided below the bottom plate 1, and the bottom pad 17 is a rubber pad, it plays a role of buffering and shock absorption.

[0024] Preferably, the heat sink 13 is a copper sheet. Since the heat sink 13 is a copper sheet, it has good thermal conductivity.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
