Description

Technical Field

[0001] This utility model relates to the field of speed reducer equipment technology, specifically a helical speed reducer. Background Technology

[0002] A helical reducer is a device that uses a helical pair to achieve speed reduction. It is a special type of reducer that converts the rotational motion of the screw into the linear motion of the nut, or vice versa. It also utilizes factors such as the pitch of the helical pair to reduce the speed and increase the torque.

[0003] In many industrial equipment and mechanical systems, the output speed of motors is often high, while the actual working load requires a relatively low speed. Through its unique structural design, the screw reducer can effectively reduce the high speed to a suitable low speed to meet the operating requirements of different working parts. However, most existing screw reducers do not have effective temperature monitoring methods, making it difficult to grasp the internal temperature changes in real time. When the internal temperature rises due to friction of mechanical parts, heat dissipation measures cannot be taken in time, which can easily lead to overheating of the equipment, affecting its performance and service life. Utility Model Content

When the internal temperature rises due to friction of mechanical parts, heat dissipation measures cannot be taken in time, which can easily lead to overheating of the equipment and affect its performance and service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a helical reducer, comprising: a reducer body, an externally threaded connecting pipe fixedly connected to one end of the top of the reducer body, a monitoring mechanism provided inside the reducer body, a protective cover one provided at the top of the monitoring mechanism, a protective cover two provided at the bottom of the monitoring mechanism, a heat dissipation box inserted into the back of the reducer body, a cover mechanism provided on the front of the heat dissipation box, a controller fixedly connected to the top middle of the heat dissipation box, a bracket fixedly connected to the inner wall of the heat dissipation box, a fan rotatably connected to one side of the bracket, and a signal receiver fixedly connected to one end of the controller.

[0006] As a further improvement of this utility model: a mounting block is fixedly connected to one side of the heat sink box, a mounting through hole is opened at one end of the mounting block, and a mounting groove is opened at one end of the back of the reducer body.

[0007] As a further embodiment of this utility model: the monitoring mechanism includes an internal threaded cover, a support post, a temperature sensor, and a signal transmitter.

The slot is located at the other end of the bottom of the support post. The elastic retaining ring is engaged inside the slot. The protective breathable sleeve is fixedly connected to the bottom of the elastic retaining ring.

[0008] As a further embodiment of this utility model: the cover mechanism includes an air inlet pipe, a filter screen and a cover, the air inlet pipe is fixedly connected to the front of the heat sink box, the filter screen is fixedly connected to the inner wall of the air inlet pipe, and the cover is threadedly connected to the front of the air inlet pipe.

A cover mechanism 7 is provided on the front of the heat dissipation box 6. A controller 8 is fixedly connected to the middle of the top of the heat dissipation box 6. A bracket 9 is fixedly connected to the inner wall of the heat dissipation box 6.

A signal receiver 11 is fixedly connected to one end of the controller 8.

[0022] Reference Figure 1 , Figure 2 and Figure 5 A mounting block 12 is fixedly connected to one side of the heat sink box 6. One end of the mounting block 12 has a mounting through hole 13. One end of the reducer body 1 has a mounting groove 14. There are two sets of mounting blocks 12, which are symmetrically arranged on both sides of the heat sink box 6. There are multiple sets of mounting through holes 13, which are symmetrically arranged at multiple ends of the two sets of mounting blocks 12. There are multiple sets of mounting grooves 14, which are symmetrically arranged at multiple ends of the reducer body 1. The design of the mounting block 12, mounting through hole 13 and mounting groove 14 facilitates the disassembly and assembly of components such as the heat sink box 6 and the controller 8.

[0023] Reference Figure 1 , Figure 3 and Figure 4The monitoring mechanism 3 includes an internal threaded cover 301, a support post 302, a temperature sensor 303, and a signal transmitter 304. The internal threaded cover 301 is threaded to the outside of the external threaded connecting pipe 2. The support post 302 is movably inserted into the inside of the external threaded connecting pipe 2. The temperature sensor 303 is fixedly connected to one bottom end of the support post 302, and the signal transmitter 304 is fixedly connected to the top of the temperature sensor 303. Protective covers 4 and 5 are both threaded to the support post 302. The mechanism also includes a slot 305, an elastic retaining ring 306, and a protective breathable sleeve 307. The slot 305 is located at the other bottom end of the support post 302. The retaining ring 306 is snapped into the slot 305. The protective ventilated sleeve 307 is fixedly connected to the bottom of the elastic retaining ring 306. The temperature sensor 303 senses the temperature change inside the reducer body 1 caused by the operation of mechanical parts and transmits the signal to the signal receiver 11 via the signal transmitter 304. The controller 8 controls the fan 10 to dissipate heat accordingly. The first protective cover 4 and the second protective cover 5 protect the signal transmitter 304 and the temperature sensor 303, making maintenance convenient and preventing damage. The protective ventilated sleeve 307 prevents liquid corrosion and ensures air circulation, making the temperature sensor 303 accurate. Its design through the elastic retaining ring 306 and the slot 305 makes it easy to disassemble and assemble.

[0024] Reference Figure 1 and Figure 6 The cover mechanism 7 includes an air inlet pipe 701, a filter screen 702, and a cover 703. The air inlet pipe 701 is fixedly connected to the front of the heat sink box 6, the filter screen 702 is fixedly connected to the inner wall of the air inlet pipe 701, and the cover 703 is threadedly connected to the front of the air inlet pipe 701. When the reducer body 1 is cooled, the filter screen 702 filters the air, effectively blocking dust, impurities, etc. from entering the heat sink box 6. When ventilation and cooling are not required or maintenance is needed, the cover 703 can be tightened to close the air inlet, which plays a certain role in dust prevention and protection.

[0025] The working principle of this utility model is as follows: During use, the temperature sensor 303 senses the change in the internal ambient temperature of the reducer body 1. As the internal mechanical parts of the reducer operate, friction and other factors generate heat, causing the temperature to rise. The temperature sensor 303 can capture these temperature changes in real time and transmit them to the signal receiver 11 through the signal transmitter 304. Then, the controller 8 controls the fan 10 to rotate to dissipate heat from the reducer body 1. The filter 702 filters the air, effectively preventing dust, impurities, etc. from entering the heat sink box 6. The protective cover 4 and the protective cover 5 provide physical protection for the signal transmitter 304 and the temperature sensor 303, preventing them from being damaged by collisions, squeezing, etc., from external objects in complex working environments, thus ensuring the stability of the equipment. The protective cover is designed for safety and reliability, and is easy to remove when maintenance, repair, or replacement of the signal transmitter 304 or temperature sensor 303 is required, making the operation convenient and quick. The protective vent sleeve 307 protects the temperature sensor 303 from liquid corrosion while allowing air to circulate around the temperature sensor 303, preventing interference with the temperature sensor 303's perception of the true temperature of the surrounding environment. The design of the elastic retaining ring 306 and the retaining groove 305 facilitates the easy installation and removal of the protective vent sleeve 307. Furthermore, the design of the mounting block 12, mounting through hole 13, and mounting groove 14, combined with the connection relationship between the internal threaded cover 301 and the external threaded connecting pipe 2, allows multiple components to be removed from the reducer body 1, facilitating the repair, maintenance, or replacement of components in the reducer body 1.
