AI Technical Summary
The existing gear reduction box gears have poor wear resistance when rotating at high speeds, resulting in frequent replacement, affecting work efficiency and causing economic losses.
A gear reduction box gear with an automatic liquid discharge component was designed. The temperature rise was detected by a temperature detector, and the electric telescopic rod was controlled to open the opening and closing plate to release coolant oil to cool the gear. The coolant was then diverted to each tooth tip of the gear through a speed-limiting flow groove and a diversion groove to ensure that the temperature does not rise too high.
It effectively extends the service life of the gear reducer, prevents the reduction of wear resistance due to excessive temperature, and ensures the normal operation of the gear.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wear-resistant gears, and more particularly to a wear-resistant gear reduction box gear. Background Art
[0002] A gear reducer is an independent, closed transmission device between the prime mover and the working machine. It is used to reduce speed and increase torque to meet operational requirements. In some cases, it is also used to increase speed, known as a speed increaser. The reduction gearbox internally consists of a gear train composed of multiple meshing gears. When the gear on the input shaft rotates, it drives the meshing gears. Because the number of teeth on different gears varies, the speed of the gears also varies accordingly. The small gear on the input shaft meshes with the large gear on the output shaft. The small gear has more teeth than the large gear, so the large gear rotates slower than the small gear. This speed difference creates a deceleration effect, reducing the output shaft speed but increasing the torque on the output shaft.
[0003] The shortcomings of the existing technology: The gears of the existing gear reducer will heat up when rotating at high speed, changing the stress of the gear reducer gears. Due to the large friction between the gear reducer gears at the meshing point and the shaft connection, the gear reducer gears have poor wear resistance and need to be replaced frequently, affecting work efficiency and causing certain economic losses. Therefore, it is necessary to provide a wear-resistant gear reducer gear to solve the above problems. Utility Model Content

[0011] The technical effects and advantages of this utility model are:
[0012] 1. The utility model is provided with an automatic liquid discharge component. When the reduction gear body generates heat during long-term operation, the temperature rise is detected by the temperature detector, and the data is transmitted to the PLC controller, which then controls the electric telescopic rod to open. Under the limit fixation of the limit block, the opening and closing plate fixedly connected thereto is driven to move backward and retract. At this time, the two ends of the double-headed telescopic rod located inside the slot move backward with the opening and closing plate, are compressed on the inclined side of the double-headed telescopic rod, and retract into the slot provided on the opening and closing plate under the elastic action of the return spring, which is conducive to opening the top of the liquid storage tube, and the coolant oil inside the liquid storage tube slowly flows out under the action of the sponge column, so as to cool the reduction gear body and ensure the service life of the reduction gear body when performing deceleration work.
[0013] 2. The utility model is provided with a speed-limiting flow groove and a diverter groove. When the coolant inside the liquid storage tube flows out to the speed-limiting flow groove, the coolant in the liquid storage tube is diverted again to each tooth tip of the reduction gear body through the diverter groove under the diversion effect of the speed-limiting flow groove. This is beneficial to ensure that the wear resistance of the reduction gear body will not be reduced due to excessive temperature during use with the cooperation of the cooling pipe, thereby ensuring the normal operation of the reduction gear body.
