Description

Technical Field

[0001] This utility model relates to the field of gearbox technology, and in particular to a horizontal gearbox. Background Technology

[0002] A horizontal machining center gearbox is a type of gearbox that uses internal gear pairs to achieve functions such as power transmission, speed change, and clutch engagement. The name "horizontal machining center" comes from "horizontal machining center," a high-precision, high-efficiency CNC machine tool. Its spindle axis is set parallel to the worktable, enabling multi-process machining of complex parts. The gearbox housing and other components are usually machined on a horizontal machining center, thus its design fully reflects the high precision and high efficiency characteristics of horizontal machining centers. This type of gearbox is often used in industrial scenarios requiring high torque, high precision, and high stability, such as machine tools and wind power generation equipment.

[0003] In the prior art, gearboxes typically use a hydraulic system for shifting gears. However, the hydraulic system requires a hydraulic pump to convert mechanical energy into hydraulic energy and then transmit power through an oil circuit. This process involves significant energy loss. Furthermore, during operation, the meshing of gears generates frictional heat, which raises the temperature inside the gearbox, affecting the lifespan of gears and bearings and even reducing the overall operating efficiency of the gearbox. Therefore, a horizontal gearbox is proposed to address the aforementioned problems. Utility Model Content

[0004] In order to solve the technical problems in the prior art, the hydraulic system needs to convert mechanical energy into hydraulic energy through a hydraulic pump and then transmit power through an oil circuit, which results in a large energy loss in the process, and the gearbox generates frictional heat during operation, causing the temperature inside the gearbox to rise. This application provides a horizontal gearbox.

[0005] The present invention discloses a horizontal gearbox, including a housing, and a gear shifting mechanism is provided inside the housing. The gear shifting mechanism includes a shift fork and a gear set. The lifting and lowering of the shift fork drives the gear set to lift and lower.

[0006] The outer side of the enclosure is provided with a ventilation mechanism, which includes a filter tube that filters the air entering the enclosure through its pore structure.

[0007] Preferably, the shifting mechanism further includes a motor, which is fixedly mounted on the lower surface of the housing, and the output shaft of the motor is rotatably connected to a groove on the lower surface of the housing via a bearing.

[0008] Preferably, the output shaft of the motor is fixedly mounted with a drive gear, the inner wall of the housing is rotatably connected to a slide rod through a bearing, the gear set is slidably sleeved on the outer surface of the slide rod, and the large gear of the gear set meshes with the drive gear.

[0009] Preferably, the inner wall of the housing is rotatably connected to a rotating rod via a bearing, and a rotating gear and a rotary gear are fixedly installed on the outer surface of the rotating rod, respectively. When the small gear of the gear set rises, it meshes with the rotating gear, and when the large gear of the gear set descends, it meshes with the rotary gear.

[0010] Preferably, a shift cylinder is fixedly installed on the lower surface of the housing, and the shift fork is fixedly installed on the outer surface of the piston rod of the shift cylinder. One end of the shift fork is rotatably connected to the lower surface of the gear set through a bearing, and the diameter of the circular hole at one end of the shift fork is larger than the diameter of the slide rod.

[0011] Preferably, the ventilation mechanism further includes ventilation holes, with multiple ventilation holes respectively opened on the front and rear surfaces of the housing. The filter tube is fixedly installed on the outer surface of the housing by bolts and is slidably connected to the inner wall of the ventilation holes.

[0012] Preferably, a vibration sensor is fixedly installed on the inner bottom wall of the enclosure, a temperature sensor is fixedly installed on the inner top wall of the enclosure, and an alarm is fixedly installed on the upper surface of the enclosure.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up a shifting mechanism, the gear set is driven to rise and fall. The motor drives the drive gear to rotate. The shifting cylinder pushes the cylinder piston rod with compressed air, which drives the shift fork fixedly installed with the piston rod to rise and fall, thereby realizing the rise and fall of the gear set. During the rise and fall of the gear set, the large gear meshes with the drive gear. After the gear set rises, its small gear meshes with the rotating gear, which drives the rotating rod fixedly installed with the rotating gear to rotate. One end of the rotating rod extending out of the housing is fixedly installed with the connecting equipment to be driven to rotate, driving it to rotate synchronously. After the gear set falls, its large gear meshes with the rotating gear, thereby realizing the shifting of the connecting equipment. This solves the technical problem in the existing technology that the gearbox usually uses a hydraulic system for shifting, but the hydraulic system needs to convert mechanical energy into hydraulic energy through a hydraulic pump and then transmit power through the oil circuit, which results in a large energy loss in the process.

[0015] 2. By setting up a ventilation mechanism, the air entering the gearbox is filtered. The ventilation holes are opened on the outer surface of the gearbox to achieve ventilation. The filter tube is slidably connected to the ventilation hole, which can be fixed without affecting the disassembly of the filter tube. The vibration sensor monitors the vibration of the gearbox in real time, and the temperature sensor monitors the internal temperature of the gearbox in real time. The alarm model can be an LK-100 hand-cranked alarm. When the vibration sensor or temperature sensor detects an abnormality, the alarm is triggered to emit an audible and visual signal. This solves the technical problem in the existing technology that the gear meshing generates frictional heat during the operation of the gearbox, which raises the internal temperature of the gearbox, affects the life of the gears and bearings, and even reduces the operating efficiency of the entire gearbox.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-6 A horizontal gearbox includes a housing 1, and a gear shifting mechanism is provided inside the housing 1. The gear shifting mechanism includes a shift fork 51 and a gear set 32. The lifting and lowering of the shift fork 51 drives the gear set 32 ​​to lift and lower.

[0025] To ensure the stability of the output shaft rotation of motor 2, the shifting mechanism also includes motor 2. Motor 2 is fixedly installed on the lower surface of housing 1. The output shaft of motor 2 is rotatably connected to the groove on the lower surface of housing 1 through bearings. By fixing motor 2 to housing 1, the output shaft of motor 2 is rotatably connected to housing 1 through bearings to ensure the stability of the output shaft rotation of motor 2. The model of motor 2 can be 28BL01AG14 DC brushless gearbox motor 2, and it is also equipped with an encoder and servo driver. The housing 1 can be made of high-strength cast iron, which has good wear resistance and impact resistance, and is suitable for bearing the high load during gearbox operation.

[0026] To drive the drive gear 3 to rotate, the output shaft of the motor 2 is fixedly mounted with the drive gear 3. The inner wall of the housing 1 is rotatably connected to the slide rod 31 via bearings. The gear set 32 ​​is slidably sleeved on the outer surface of the slide rod 31. The large gear of the gear set 32 ​​meshes with the drive gear 3. The output shaft of the motor 2 is fixedly mounted with the drive gear 3, driving the drive gear 3 to rotate. The slide rod 31 is rotatably connected to the housing 1 via bearings, ensuring the stability of the slide rod 31's rotation. The gear set 32 ​​is slidably sleeved with the slide rod 31, fixing it without affecting its lifting and lowering. The large gear of the gear set 32 ​​meshes with the drive gear 3 during the lifting and lowering process. After the gear set 32 ​​rises, its small gear meshes with the rotating gear 41, driving the rotating rod 4, which is fixedly mounted with the rotating gear 41, to rotate. One end of the rotating rod 4 extends out of the housing 1 and is fixedly mounted with the connecting equipment that needs to be driven to rotate, driving it to rotate synchronously. After the gear set 32 ​​falls, its large gear meshes with the rotating gear 42, thereby realizing the shifting of the connecting equipment.

[0027] To ensure the stability of the rotation of the rotating rod 4, the inner wall of the housing 1 is rotatably connected to the rotating rod 4 via bearings. Rotating gears 41 and 42 are fixedly mounted on the outer surface of the rotating rod 4. When the small gear of gear set 32 ​​rises, it meshes with rotating gear 41; when the large gear of gear set 32 ​​descends, it meshes with rotating gear 42. The housing 1 is rotatably connected to the rotating rod 4 via bearings to ensure the stability of the rotation of the rotating rod 4. The rotating rod 4 is fixedly mounted to rotating gears 41 and 42. When gear set 32 ​​rises, its small gear meshes with rotating gear 41, driving the rotating gears 41 and 42. The rotating rod 4, which is fixedly installed on the wheel 41, rotates. One end of the rotating rod 4 extends out of the housing 1 and is fixedly installed with the connecting equipment that needs to be driven to rotate, causing it to rotate synchronously. After the gear set 32 ​​descends, the large gear on it meshes with the rotating gear 42, thereby realizing the shifting of the connecting equipment. The materials of the drive gear 3, slide rod 31, gear set 32, rotating rod 4, rotating gear 41 and rotating gear 42 can all be alloy steel, which has high hardness and wear resistance, and good fatigue resistance, which can extend the service life of the shifting mechanism. The surface can be heat-treated, such as quenching and carburizing, to improve hardness.

[0028] To drive the shift fork 51, which is fixedly mounted to the piston rod, a shift cylinder 5 is fixedly mounted on the lower surface of the housing 1. The shift fork 51 is fixedly mounted on the outer surface of the piston rod of the shift cylinder 5. One end of the shift fork 51 is rotatably connected to the lower surface of the gear set 32 ​​via a bearing. The diameter of the circular hole at one end of the shift fork 51 is larger than the diameter of the slide rod 31. It is fixedly mounted to the shift cylinder 5 through the housing 1. The model of the shift cylinder 5 can be 2159 107. The 002B shift cylinder 5 is equipped with a pneumatic proportional valve and a position sensor. The pneumatic proportional valve enables precise control of the cylinder stroke, improving shift accuracy. The position sensor provides real-time feedback on the position of the shift fork 51, ensuring the accuracy of the shifting action. The shift cylinder 5 uses compressed air to push the cylinder piston rod, which in turn drives the shift fork 51, which is fixedly mounted to the piston rod, to rise and fall, thereby raising and lowering the gear set 32. The gear set 32 ​​and the shift fork 51 are rotatably connected by bearings. While the gear set 32 ​​is raised and lowered, the rotation of the gear set 32 ​​does not affect the shift fork 51. Because the diameter of the circular hole at one end of the shift fork 51 is larger than the diameter of the slide rod 31, while the gear set is raised and lowered, the rotation of the slide rod 31 does not affect the shift fork 51. The shift fork 51 can also be made of alloy steel, which has excellent tensile, compressive, and bending strength, and can withstand the impact load and repeated stress during the shifting process. It is not easily deformed or broken, and the surface can be heat-treated, such as quenching and carburizing, to improve hardness.

[0029] By setting up a shifting mechanism, the gear set 32 ​​is driven to rise and fall. The motor 2 drives the drive gear 3 to rotate. The shifting cylinder 5 pushes the cylinder piston rod with compressed air, which drives the shift fork 51 fixedly installed with the piston rod to rise and fall, thereby realizing the rise and fall of the gear set 32. During the rise and fall of the gear set 32, the large gear meshes with the drive gear 3. After the gear set 32 ​​rises, its small gear meshes with the rotating gear 41, which drives the rotating rod 4 fixedly installed with the rotating gear 41 to rotate. The end of the rotating rod 4 extending out of the housing 1 is fixedly installed with the connecting equipment that needs to be driven to rotate, driving it to rotate synchronously. After the gear set 32 ​​falls, its large gear meshes with the rotating gear 42, thereby realizing the shifting of the connecting equipment. This solves the technical problem in the prior art that the gearbox usually uses a hydraulic system for shifting, but the hydraulic system needs to convert mechanical energy into hydraulic energy through a hydraulic pump and then transmit power through the oil circuit, which results in a large energy loss in the process.

[0030] In order to filter the air entering the chamber 1, a ventilation mechanism is provided on the outer side of the chamber 1. The ventilation mechanism includes a filter pipe 61, which filters the air entering the chamber 1 through its pore structure.

[0031] To facilitate subsequent cleaning and maintenance, the ventilation mechanism also includes ventilation holes 6. Multiple ventilation holes 6 are respectively opened on the front and rear surfaces of the housing 1. The filter tube 61 is fixedly installed on the outer surface of the housing 1 with bolts and is slidably connected to the inner wall of the ventilation hole 6. Ventilation is achieved through the ventilation holes 6 on the outer surface of the housing 1. The filter tube 61 is fixedly installed to the housing 1 with bolts, which facilitates disassembly for subsequent cleaning and maintenance. The filter tube 61 is slidably connected to the ventilation hole 6, which does not affect the disassembly of the filter tube 61 while fixing it. A sealing element can be set on the contact surface between the filter tube 61 and the ventilation hole 6. The sealing element can be made of fluororubber, which has good high temperature resistance, oil resistance, and chemical resistance. The filter tube 61 can be made of stainless steel, which has sufficient mechanical strength and can resist the corrosion of lubricating oil and environmental moisture. At the same time, the surface is smooth, does not easily adhere to dirt, and is easy to clean.

[0032] To monitor the gearbox vibration in real time, a vibration sensor 7 is fixedly installed on the inner bottom wall of the housing 1, a temperature sensor 71 is fixedly installed on the inner top wall of the housing 1, and an alarm 72 is fixedly installed on the upper surface of the housing 1. The vibration sensor 7 is fixedly installed on the housing 1 to monitor the gearbox vibration in real time. The position of the vibration sensor 7 can be replanned and installed according to actual needs; an 8011 series vibration sensor 7 can be selected. Similarly, the temperature sensor 71 is fixedly installed on the housing 1 to monitor the internal temperature of the gearbox in real time. Likewise, the position of the temperature sensor 71 can be replanned and installed according to actual needs; a WZP-F2001 gearbox temperature sensor 71 can be used. The alarm 72 is fixedly installed on the housing 1; an LK-100 hand-cranked alarm 72 can be used. When either the vibration sensor 7 or the temperature sensor 71 detects an abnormality, the alarm 72 is triggered to emit an audible and visual signal.

[0033] By setting up a ventilation mechanism, the air entering the housing 1 is filtered. Ventilation holes 6 are opened on the outer surface of the housing 1 to achieve ventilation. The filter tube 61 is slidably connected to the ventilation hole 6, which can be fixed without affecting the disassembly of the filter tube 61. The vibration sensor 7 monitors the vibration of the gearbox in real time, and the temperature sensor 71 monitors the internal temperature of the gearbox in real time. The alarm 72 can be an LK-100 hand-cranked alarm 72. When the vibration sensor 7 or the temperature sensor 71 detects an abnormality, the alarm 72 is triggered to emit an audible and visual signal. This solves the technical problem in the prior art that the gear meshing generates frictional heat during the operation of the gearbox, which raises the internal temperature of the gearbox, affects the life of the gears and bearings, and even reduces the operating efficiency of the entire gearbox.

[0034] Working principle: When the gearbox is needed, determine the best installation position of the gearbox according to the interface and space of the application equipment. Use bolts to firmly fix the gearbox to the equipment base to ensure stable connection and reduce vibration transmission. Then, the rotating rod 4 extending out of the housing 1 is precisely aligned and firmly connected with the connecting parts that need to be driven, such as the worktable and rollers.

[0035] The staff sends a start command through the main control system to start the motor 2, which starts to run at a preset low speed or a specific gear, driving the drive gear 3 to rotate. The power output of the motor 2 is transmitted to the rotating rod 4 through the gear set 32 ​​and meshes with the gear on the rotating rod 4, thereby driving the connecting parts to rotate.

[0036] When a gear shift is required, the operator issues a shift command through the control system. The control system sends a signal to the pneumatic proportional valve according to the command, controlling the compressed air to enter or exit the shift cylinder 5. The cylinder piston rod moves, driving the shift fork 51 to rise and fall. The shift fork 51 pushes the gear set 32 ​​to move up and down along the slide bar 31. After the gear set 32 ​​moves, the small gear and large gear on it mesh with different gears. The rising gear meshes with the rotating gear 41, and the falling gear meshes with the rotating gear 42. The position sensor detects that the shift fork 51 has reached the target position and sends a signal back to the control system. The control system confirms that the gear shift is complete and adjusts the speed and torque of the motor 2 as needed to adapt to the new gear requirements.

[0037] During this process, the filter tube 61 in the ventilation hole 6 ensures air circulation inside and outside the box 1, heat dissipation, and filters the incoming air. At the same time, the control system continuously monitors the signals of the vibration sensor 7 and the temperature sensor 71 and compares them with the set threshold. If the vibration or temperature rises abnormally and exceeds the threshold, the control system triggers the alarm 72 to issue an alarm and prompt the operator to check.

[0038] Disassemble filter tube 61 periodically according to usage intensity, clean filter tube 61 and the dust inside filter tube 61, check the aging of filter tube 61 and seals, and replace if necessary. Regularly check oil level and oil quality. If the oil turns black, has an odor, or contains a large amount of metal shavings, the lubricating oil needs to be replaced. When replacing, try to drain the old oil and flush the inside with new oil. Strictly follow the manufacturer's recommended oil type and replacement cycle. Regularly check the wear of key components such as gears, bearings, and shafts. This can be done by disassembly inspection or by judging based on vibration and temperature data. Regularly check whether the shift cylinder 5, shift fork 51, slide bar 31, etc. are worn or stuck. Regularly check the accuracy of vibration and temperature sensor 71 and calibrate if necessary.

[0039] When lubrication is required, splash lubrication is used, that is, when the gear rotates, the lubricating oil is thrown up and splashed onto each lubrication point. At the same time, depending on the complexity of the structure, an oil pump can be selected to perform forced circulation lubrication through the lubricating oil pipeline. The design of lubrication and pipeline is existing technology, so it will not be explained in detail here.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
