Description

Technical Field

[0001] The utility model relates to a steering gear, in particular to a spiral gear steering gear, belonging to the technical field of steering gears. Background Art

[0002] The function of the steering gear is to appropriately transform the steering torque and steering angle from the steering wheel (mainly to reduce speed and increase torque), and then output it to the steering rod mechanism to make the car turn. Therefore, the steering gear is essentially a reduction transmission device. There are many types of steering gears, such as rack and pinion type, recirculating ball type, worm crank pin type, power steering gear, etc. The steering gear is a power transmission mechanism and a series of reducers. It has a wide range of applications in the industrial field. Steering gears have now achieved standardization and diversified specifications.

[0003] During the operation of the helical gear steering gear, the internal gears will generate high temperature under high-speed rotation, so cooling oil will be poured into the steering gear to cool the gears. Since the cooling oil is circulated in the steering gear, the temperature of the cooling oil will gradually increase. The traditional helical gear steering gear does not have the function of quickly cooling the cooling oil, which affects the cooling effect of the cooling oil on the gears, indirectly shortening the service life of the steering gear.

[0004] Therefore, there is an urgent need for an improved helical gear steering gear to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a helical gear steering gear, in which a cooling mechanism is arranged between an oil outlet pipe and an oil inlet pipe, so as to cool down the cooling oil in a main body of the helical gear steering gear. After the cooling oil is cooled down, the cooling effect on the gears inside the main body of the helical gear steering gear will not be changed, thereby avoiding the influence of the cooling oil temperature on the cooling effect on the gears being too high.

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0007] A helical gear steering gear comprises a helical gear steering gear body, on which a plurality of oil outlet pipes and oil inlet pipes are symmetrically mounted, a cooling mechanism being arranged between the oil outlet pipes and the oil inlet pipes, the cooling mechanism comprising a plurality of first fixing plates fixedly mounted on the helical gear steering gear body, a processing box connected to the oil outlet pipes and the oil inlet pipes being fixedly mounted on the first fixing plates, a plurality of heat absorbing sheets being fixedly mounted inside the processing box, a plurality of heat dissipating fins connected to the heat absorbing sheets being fixedly mounted on the front of the processing box, a semiconductor refrigerator being fixedly mounted on the oil inlet pipe, a box body being fixedly mounted on the surface of the processing box, and a battery connected to the semiconductor refrigerator being arranged inside the box body.

[0008] Preferably, two slide rails are symmetrically and fixedly installed on the front side of the box body, and a sealing plate is slidably installed between the two slide rails.

[0009] Preferably, the top and the bottom of the box body are both provided with slide grooves, and a limit plate is slidably installed on the slide grooves, and limit frames are fixedly installed on the two sealing plates.

[0010] Preferably, a plurality of first magnetic blocks are fixedly mounted on the limiting plate, and a plurality of second magnetic blocks that are attracted to the first magnetic blocks are fixedly mounted on the limiting frame.

[0011] Preferably, the surface of the limiting plate is provided with anti-slip grooves.

[0012] Preferably, a voltmeter is fixedly mounted on the box, and the voltmeter is electrically connected to the battery.

[0013] Preferably, a second fixing plate is fixedly mounted on one side of the processing box, and a heat dissipation fan is fixedly mounted on the second fixing plate.

[0014] The utility model has at least the following beneficial effects:

[0015] By setting up the cooling mechanism, the cooling oil can be cooled. After the cooling oil in the helical gear steering gear body is transported to the processing box through the oil outlet pipe, the multiple heat-absorbing plates in the processing box can absorb the temperature of the cooling oil and transfer it to the outer heat dissipation fins for heat dissipation to reduce the temperature of the cooling oil. At the same time, a semiconductor refrigerator is arranged on the oil inlet pipe. The semiconductor refrigerator is powered by a battery and started to cool the oil inlet pipe, so that the cooling oil circulating in the oil inlet pipe is further cooled, thereby improving its cooling effect. After the cooling oil is cooled, its cooling effect on the internal gears of the helical gear steering gear body will not change, thereby avoiding the cooling oil temperature being too high and affecting the cooling effect on the gears.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 4 As shown, this embodiment provides a helical gear steering gear embodiment.

[0024] A helical gear steering gear comprises a helical gear steering gear body 1, on which a plurality of oil outlet pipes 2 and oil inlet pipes 3 are symmetrically mounted, a cooling mechanism 4 is arranged between the oil outlet pipes 2 and the oil inlet pipes 3, the cooling mechanism 4 comprises a plurality of first fixing plates 5 fixedly mounted on the helical gear steering gear body 1, a processing box 6 connected to the oil outlet pipes 2 and the oil inlet pipes 3 is fixedly mounted on the first fixing plates 5, a plurality of heat absorbing sheets 7 are fixedly mounted inside the processing box 6, a plurality of heat dissipating fins 8 connected to the heat absorbing sheets 7 are fixedly mounted on the front of the processing box 6, a semiconductor refrigerator 9 is fixedly mounted on the oil inlet pipe 3, a box body 10 is fixedly mounted on the surface of the processing box 6, and a battery 11 connected to the semiconductor refrigerator 9 is arranged inside the box body 10. By setting the cooling mechanism 4, the cooling oil can be cooled. After the cooling oil in the helical gear steering gear body 1 is transported to the processing box 6 through the oil outlet pipe 2, the multiple heat absorption plates 7 in the processing box 6 can absorb the temperature of the cooling oil and transfer it to the outer heat dissipation fins 8 for heat dissipation to reduce the temperature of the cooling oil. At the same time, a semiconductor refrigerator 9 is arranged on the oil inlet pipe 3. The semiconductor refrigerator 9 is powered by the battery 11 to start cooling the oil inlet pipe 3, so that the cooling oil circulating in the oil inlet pipe 3 is further cooled, thereby improving its cooling effect. After the cooling oil is cooled, the cooling effect on the internal gears of the helical gear steering gear body 1 will not change, thereby avoiding the cooling oil temperature being too high and affecting the cooling effect on the gears.

[0025] Two slide rails 12 are symmetrically fixedly installed on the front of the box body 10, and a sealing plate 13 is slidably installed between the two slide rails 12. The top and bottom of the box body 10 are provided with slide grooves 14, and limit plates 15 are slidably installed on the slide grooves 14. Limiting frames 16 are fixedly installed on the two sealing plates 13. A plurality of first magnetic blocks 17 are fixedly installed on the limiting plates 15, and a plurality of second magnetic blocks 18 that are mutually attracted to the first magnetic blocks 17 are fixedly installed on the limiting frames 16. By setting the slide rail 12 and the sealing plate 13, two sealing plates 13 are set on the front side of the box body 10 to seal and protect the battery 11, so as to prevent the battery 11 from being exposed to the outside and being damaged. At the same time, the sealing plate 13 is slidably installed by the slide rail 12, so that the sealing plate 13 is easier to open and close on the box body 10, and the battery 11 is convenient to replace. By setting the slide groove 14, the limit plate 15 and the limit frame 16, after the two sealing plates 13 are closed, the limit plate 15 is pushed to insert one end of it into the limit frame 16. After the limit plate 15 is combined with the limit frame 16, the sealing plate 13 can be limited, so that the two sealing plates 13 are tightly fitted to prevent loosening. By setting the first magnetic block 17 and the second magnetic block 18, the adsorption of the first magnetic block 17 and the second magnetic block 18 can further enhance the firmness of the combination of the limit plate 15 and the limit frame 16, and strengthen the limiting effect of the sealing plate 13.

By providing the voltmeter 19, the power of the battery 11 can be detected to observe the remaining power of the battery 11. By providing the second fixed plate 20 and the heat dissipation fan 21, the heat dissipation rate of the heat dissipation fins 8 can be improved by starting the heat dissipation fan 21 to blow air to the multiple heat dissipation fins 8.

[0027] In this embodiment, if Figure 1-Figure 4 As shown, the working process of a spiral gear steering gear provided in this embodiment is as follows:

[0028] After the cooling oil in the helical gear steering gear body 1 is transported to the processing box 6 through the oil outlet pipe 2, the multiple heat absorbing plates 7 in the processing box 6 can absorb the temperature of the cooling oil and transfer it to the outer heat dissipation fins 8 for heat dissipation to reduce the temperature of the cooling oil. At the same time, a semiconductor refrigerator 9 is arranged on the oil inlet pipe 3. The semiconductor refrigerator 9 is powered by the battery 11 to start cooling the oil inlet pipe 3, so that the cooling oil circulating in the oil inlet pipe 3 is further cooled, thereby improving its cooling effect. After the cooling oil is cooled, its cooling effect on the internal gears of the helical gear steering gear body 1 will not change. After the two sealing plates 13 are closed, the limit plate 15 is pushed to insert one end of the limit plate 15 into the limit frame 16. After the limit plate 15 is combined with the limit frame 16, the sealing plate 13 can be limited, so that the two sealing plates 13 are tightly fitted to prevent loosening. The two sealing plates 13 can play a role of sealing and protecting the battery 11 to prevent the battery 11 from being exposed to the outside and damaged.

[0029] In summary, in the present embodiment, according to a helical gear steering gear of the present embodiment, two sealing plates 13 are arranged on the front of the box body 10 through the arrangement of the slide rail 12 and the sealing plate 13, which can play a role of sealing and protecting the battery 11, and prevent the battery 11 from being exposed to the outside and damaged. At the same time, the sealing plate 13 is slidably installed through the slide rail 12, so that the sealing plate 13 is easier to open and close on the box body 10, and the battery 11 is convenient to replace. Through the arrangement of the slide groove 14, the limit plate 15 and the limit frame 16, after the two sealing plates 13 are closed, the limit plate 15 is pushed to insert one end of the limit plate 15 into the limit frame 16, and the limit plate 15 is combined with the limit frame 16 to limit the sealing plate 13 , so that the two sealing plates 13 are tightly fitted to prevent loosening. Through the setting of the first magnetic block 17 and the second magnetic block 18, the adsorption of the first magnetic block 17 and the second magnetic block 18 can further improve the firmness of the combination of the limit plate 15 and the limit frame 16, and strengthen the limiting effect of the sealing plate 13. By setting anti-slip grooves on the surface of the limit plate 15, the friction of the limit plate 15 is increased, and it is easier to push it. Through the setting of the voltmeter 19, the power of the battery 11 can be detected to observe the remaining power of the battery 11. Through the setting of the second fixed plate 20 and the heat dissipation fan 21, the heat dissipation fan 21 is started to blow air to the multiple heat dissipation wings 8, which can improve the heat dissipation rate of the heat dissipation wings 8.
