Description

Technical Field

[0001] The utility model relates to the technical field of gear boxes, in particular to a gear box for a water-cooled heat exchanger. Background Art

[0002] The gearbox plays an important role in the water-cooled exchanger. It can provide power transmission and speed regulation for the motors of the water pump components and fan components in the water-cooled exchanger. The gearbox can convert the high-speed rotation of the motor into a suitable speed and realize the speed change function through the combination of its internal gears, ensuring that the motor output is stable and meets the power requirements of the water-cooled exchanger, thereby ensuring the smooth operation and efficient work of the entire system.

[0003] The existing gearbox for water-cooled heat exchanger uses a simple cover plate to seal the oil change port. Since the sealing performance of the cover mainly depends on the tightening of bolts, when facing the working environment of the water-cooled heat exchanger with high water vapor and humidity, external moisture can easily enter the gearbox, which can easily cause bearing wear, increased clearance, increased noise, and even pitting and reduced fatigue life of transmission parts. Therefore, a gearbox for water-cooled heat exchanger is proposed to provide a gearbox assembly with high use stability for the motor of the water-cooled heat exchanger. By using the piston assembly in conjunction with the cover plate, the sealing performance between the oil change port and the cover plate of the gearbox can be greatly improved, effectively preventing external dust, water vapor and other pollutants from invading the interior of the gearbox, and ensuring the stability and life of the lubricating oil, gears and shaft parts inside the gearbox.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] In order to ensure the stability and life of the gearbox, Figure 1-7 As shown, the gearbox for a water-cooled heat exchanger described in the present invention includes a gearbox 1, an oil change port 2, a cover plate 3 and a piston assembly 4. The oil change port 2 is opened at the top of the gearbox 1, the cover plate 3 is covered on the oil change port 2, and the piston assembly 4 is arranged on the cover plate 3. The corners of the cover plate 3 are installed and connected to the top of the gearbox 1 by bolts.

[0026] When in use, the gearbox 1, the oil change port 2, the cover plate 3 and the piston assembly 4 provide a gearbox assembly with high stability for the motor of the water-cooled heat exchanger. The piston assembly 4 cooperates with the cover plate 3 to greatly improve the sealing between the oil change port 2 and the cover plate 3 of the gearbox 1, effectively preventing external pollutants such as dust and water vapor from invading the interior of the gearbox 1, thereby ensuring the stability and service life of the gearbox 1.

[0027] In order to improve the sealing performance, for example, Figure 1-7 As shown, the present invention further includes a circle of embedding grooves 21 formed on the outer periphery of the oil change port 2 , and a rubber lining 22 adhered to the inner wall of the embedding grooves 21 .

[0028] A rubber ring 31 having a size corresponding to the embedding groove 21 is adhered to the outer periphery of the bottom of the cover plate 3 , and the inner cavity of the rubber ring 31 is a hollow structure.

[0029] During use, the rubber lining 22 improves the sealing performance of the rubber ring 31 after it enters the embedding groove 21 .

[0030] In order to achieve the desired fit after covering, for example, Figure 1-7 As shown, the present invention further includes that the piston assembly 4 includes a mounting sleeve 41 and an air pipe 42 , one end of the air pipe 42 is connected to the rubber ring 31 and communicates with the inner cavity of the rubber ring 31 .

[0031] The mounting sleeve 41 is welded to the top of the cover plate 3, and a piston sleeve 43 is provided in the mounting sleeve 41. An internal threaded sleeve 44 is connected to one end of the piston sleeve 43, and a threaded rod 45 is inserted into the internal thread of the internal threaded sleeve 44. A piston 46 is connected to the piston sleeve 43 and located at one end of the threaded rod 45. A sealing ring 47 is provided on the outer periphery of the piston 46, and a knob 48 is connected to the end of the threaded rod 45 away from the piston 46.

[0032] During use, the piston assembly 4 is used to pressurize the hollow rubber ring 31 with air, so that the rubber ring 31 fits better with the embedding groove 21 .

[0033] The present invention further comprises that one end of the piston sleeve 43 away from the internal threaded sleeve 44 is connected to the other end of the air pipe 42 and communicates with each other.

[0034] When the utility model is in use, the gear box 1 is assembled on the motor of the water-cooled heat exchanger, and the transmission speed of the motor is adjusted by the gear box 1 to transmit the operating power to the fan, water pump and other mechanisms required to be driven in the water-cooled heat exchanger. During use, the lubricating oil inside the gear box 1 is replaced through the oil change port 2. During this period, the oil change port 2 is covered by the cover plate 3. After covering, the rubber ring 31 at the bottom of the cover plate 3 will be embedded in the embedded groove 21 to form a preliminary seal. The cover plate 3 is tightened and fixed to the gear box 1 by bolts. After the cover plate 3 is covered on the oil change port 2, the personnel can rotate the knob 48 to The threaded rod 45 moves within the internal thread of the internal threaded sleeve 44, thereby moving the piston 46 within the piston sleeve 43, pushing the air at the rear end of the piston sleeve 43, and discharging the air into the rubber ring 31 through the air pipe 42, causing the rubber ring 31 to expand within the embedded groove 21, thereby achieving a better fit between the rubber ring 31 and the rubber lining 21, greatly improving the seal between the rubber lining 22 and the rubber ring 31, and similarly further improving the seal between the cover plate 3 and the gear box 1, effectively preventing external water vapor, dust and other foreign matter from entering the gear box 1, thereby ensuring the stability and service life of the gear box 1 when used in a water-cooled heat exchanger.
