This utility model relates to the field of slewing drive bearing technology, and proposes a slewing drive bearing for special operation vehicles. The slewing drive bearing, protective housing, and mounting housing include: a lubrication assembly, a worm gear, an injection pipe, and a discharge pipe. When temperature and vibration sensors detect that the temperature and vibration force exceed set standards, the information is transmitted to the controller. The controller then activates a miniature oil pump to replenish lubricating oil to the slewing drive bearing, effectively preventing friction damage between the worm gear and the bearing. If the temperature and vibration sensors continuously detect that the temperature and vibration force exceed the set standards, the controller activates an audible and visual alarm and a transceiver to send alarm information to remote devices and to alert on-site personnel. This effectively prevents the need for lubricating oil changes between the worm gear and the slewing drive bearing, thus improving the service life of the slewing drive bearing.

Description

Technical Field

[0001] This utility model relates to the field of rotary drive bearing technology, specifically to a rotary drive bearing for special operation vehicles. Background Technology

[0002] A rotary drive, also known as a rotary reducer or turntable reducer, is a full-circumferential rotary reduction transmission mechanism that integrates a drive power source. It uses a slewing bearing as the driven component and attachment component. The driving component, drive source, and housing are attached to one of the inner and outer rings, while the other ring serves as the driven component and connecting base. This integrates rotation, reduction, and drive functions. Based on the transmission method, it can be divided into gear rotary drives and worm gear rotary drives. The former has high transmission efficiency, while the latter has a large reduction ratio and self-locking function. Its core components are made of high-quality steel, and the worm gear undergoes glow discharge ion de-preciation treatment, enabling it to withstand axial force, radial force, and overturning moment.

[0003] Testing the friction force of gears and worm gears is a complex engineering task. Direct measurement of friction force is very difficult, so we usually evaluate it by measuring its results or effects. Friction force directly leads to power loss and reduced efficiency. The work done by friction force is converted into heat, causing the temperature of the components to rise. However, during the implementation of the relevant technology, the following problems were found in the existing technology: During use, friction occurs between the gear and the worm, mostly due to lack of lubricating oil. Currently, most rotary drive bearings lack the function of automatically detecting and adding lubricating oil, which leads to friction between the gear and the worm, damaging the rotary drive bearing and reducing its service life. Therefore, a rotary drive bearing for special operation vehicles is proposed. Utility Model Content

[0004] This utility model proposes a slewing drive bearing for special operation vehicles, which solves the problem that most slewing drive bearings in related technologies lack the function of automatically detecting and adding lubricating oil, resulting in friction between the gears and worm gear, which damages the slewing drive bearing and reduces its service life.

[0005] The technical solution of this utility model is as follows: A rotary drive bearing for special operation vehicles, comprising a rotary drive bearing, a protective shell, and a mounting shell, including: a lubrication assembly, a worm gear, an injection pipe, and a discharge pipe. The rotary drive bearing is disposed inside the protective shell and the mounting shell, and the mounting shell is fixedly connected to the outer wall of the protective shell. The lubrication assembly is disposed between the mounting housing and the protective housing, and the worm gear is meshed with the rotary drive bearing.

[0006] Preferably, the injection tube is fixedly installed through the top of the mounting shell, the discharge tube is fixedly installed through the bottom of the protective shell, and both the injection tube and the discharge tube are provided with sealing caps at their ends.

[0007] Preferably, the lubrication assembly includes a detection mechanism, a control mechanism, and a lubrication mechanism. The lubrication mechanism is disposed on the outer side wall of the protective housing. The detection mechanism and the control mechanism are jointly disposed on the top of the mounting housing, with the control mechanism located on one side of the detection mechanism.

[0008] Preferably, the detection mechanism includes a sealed box, a temperature sensor, and a vibration sensor. The temperature sensor and the vibration sensor are fixedly installed together on the inner bottom wall of the sealed box, the vibration sensor is located on one side of the temperature sensor, and the sealed box is fixedly installed on the top of the mounting shell.

[0009] Preferably, the control mechanism includes a mounting box, a controller, an information transceiver, and an audible and visual alarm. The audible and visual alarm is fixedly installed on the top of the mounting box, and the mounting box is fixedly installed on the top of the mounting shell. The controller and the information transceiver are jointly fixedly installed on the inner bottom wall of the mounting box, and the information transceiver is located on one side of the controller.

[0010] Preferably, the refueling mechanism includes a semi-circular oil storage tank, a refueling pipe, and a micro oil pump. The micro oil pump is fixedly installed at one end of the semi-circular oil storage tank, which is fixedly installed on the outer side wall of the protective shell. The input end of the micro oil pump extends into the interior of the semi-circular oil storage tank, and the output end of the micro oil pump extends into the interior of the mounting shell through a pipe. The refueling pipe is fixedly installed through the top of the semi-circular oil storage tank, and a sealing pipe is provided at the top of the refueling pipe. The controller is electrically connected to the information transceiver, the audible and visual alarm, the temperature sensor, the vibration sensor, and the micro oil pump.

[0011] The working principle and beneficial effects of this utility model are as follows: When the temperature and vibration sensors detect that the temperature and vibration force exceed the set standards, the information is transmitted to the controller. The controller then activates a miniature oil pump to extract lubricating oil from the semi-circular oil tank. The extracted lubricating oil is delivered to the interior of the mounting housing to replenish lubricating oil between the worm gear and the rotary drive bearing, effectively preventing friction damage between the worm gear and the rotary drive bearing. If the temperature and vibration sensors continuously detect that the temperature and vibration force exceed the set standards, the controller activates an audible and visual alarm and a transceiver. The transceiver sends alarm information to remote equipment, while the audible and visual alarm alerts personnel on-site, effectively prompting the replacement of lubricating oil in the worm gear and rotary drive bearing, preventing friction damage between the worm gear and the rotary drive bearing, and thus extending the service life of the rotary drive bearing.

The protective housing 2 provides a seal to protect the rotary drive bearing 1, effectively preventing dust and impurities from entering and avoiding contamination of the lubricating oil. The lubrication assembly 4 is used to detect whether there is insufficient oil between the rotary drive bearing 1 and the worm gear 5, causing friction, and to provide oil replenishment or an oil shortage alarm.

[0016] As one embodiment of this utility model, refer to Figure 1 and Figure 4 The lubrication assembly 4 includes a detection mechanism 41, a control mechanism 42, and a lubrication mechanism 43. The lubrication mechanism 43 is located on the outer wall of the protective shell 2. The detection mechanism 41 and the control mechanism 42 are both located on the top of the mounting shell 3. The control mechanism 42 is located on one side of the detection mechanism 41. The detection mechanism 41 includes a sealing box 411, a temperature sensor 412, and a vibration sensor 413. The temperature sensor 412 and the vibration sensor 413 are both fixedly installed on the inner bottom wall of the sealing box 411. The vibration sensor 413 is located on one side of the temperature sensor 412. The sealing box 411 is fixedly installed on the top of the mounting shell 3. With the above configuration, the vibration sensor 413 is used to detect the vibration force of the movement between the worm gear 5 and the rotary drive bearing 1, and the temperature sensor 412 is used to detect the temperature generated by the movement between the worm gear 5 and the rotary drive bearing 1.

[0017] As one embodiment of this utility model, refer to Figure 1 and Figure 4The control mechanism 42 includes a mounting box 421, a controller 422, an information transceiver 423, and an audible and visual alarm 424. The audible and visual alarm 424 is fixedly installed on the top of the mounting box 421, and the mounting box 421 is fixedly installed on the top of the mounting shell 3.

It should be noted that the remote settings can be any mobile phone or computer. The audible and visual alarm 424 is used to alert staff on-site.

[0018] As one embodiment of this utility model, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The refueling mechanism 43 includes a semi-circular oil storage tank 431, a refueling pipe 432, and a miniature oil pump 433. The miniature oil pump 433 is fixedly installed at one end of the semi-circular oil storage tank 431, which is fixedly installed on the outer wall of the protective shell 2. The input end of the miniature oil pump 433 extends into the interior of the semi-circular oil storage tank 431, and the output end of the miniature oil pump 433 extends into the interior of the mounting shell 3 through a pipe. The refueling pipe 432 is fixedly installed through the top of the semi-circular oil storage tank 431, and the top of the refueling pipe 432 is provided with... With a sealed tube, the controller 422 is electrically connected to the information transceiver 423, the audible and visual alarm 424, the temperature sensor 412, the vibration sensor 413, and the micro oil pump 433. With the above settings, by starting the micro oil pump 433, the micro oil pump 433 draws lubricating oil from the semi-circular oil storage tank 431 and delivers the drawn lubricating oil to the inside of the mounting shell 3 to replenish the lubricating oil between the worm gear 5 and the rotary drive bearing 1, effectively preventing friction damage between the worm gear 5 and the rotary drive bearing 1.

[0019] Working principle: During use, the vibration sensor 413 is used to detect the vibration force of the movement between the worm 5 and the rotary drive bearing 1, and the temperature sensor 412 is used to detect the temperature generated by the movement between the worm 5 and the rotary drive bearing 1. When the temperature sensor 412 and the vibration sensor 413 detect that the temperature and vibration force exceed the set standard, it indicates that there is a lack of lubricating oil between the worm 5 and the rotary drive bearing 1 and friction is occurring. The temperature sensor 412 and the vibration sensor 413 transmit the information to the controller 422, and the controller 422 controls the micro oil pump 433 to start. The micro oil pump 433 extracts the lubricating oil from the semi-circular oil tank 431 and delivers the extracted lubricating oil to the interior of the mounting shell 3 to replenish the lubricating oil between the worm 5 and the rotary drive bearing 1, effectively preventing friction damage between the worm 5 and the rotary drive bearing 1. If the temperature sensor 412 and vibration sensor 413 continuously detect that the temperature and vibration force exceed the set standards, the controller 422 controls the audible and visual alarm 424 and the information transceiver 423 to start. The information transceiver 423 is used to send alarm information to remote equipment, and the audible and visual alarm 424 is used to alert the staff on site. This effectively allows for the replacement of the lubricating oil between the worm gear 5 and the rotary drive bearing 1, effectively preventing friction damage between the worm gear 5 and the rotary drive bearing 1, thereby improving the service life of the rotary drive bearing 1.
