[0022] The speed reducer 2 comprises a helical gear one 21 arranged at the output end of the drive motor 3, a helical gear two 22 meshed with the helical gear one 21, a gear three 23 coaxial with the helical gear two 22, a gear four 24 meshed with the gear three 23, a gear five 25 coaxial with the gear four 24, a gear six 26 meshed with the gear five 25, a gear seven 27 meshed with the gear six 26, an output shaft 28 coaxial with the gear seven 27, and the output shaft 28 connected with the stirring mechanism 4.
[0023] The outer side of the output shaft 28 is sleeved with an oil seal 8, and the oil seal 8 is connected with the shell 1.
[0024] The helical gear two 22 and the gear three 23 are both made of plastic material, and the helical gear two 22 and the gear three 23 are coaxially rotatably arranged in the shell 1 through a gear shaft one 281, and the gear shaft one 281 is made of metal material.
[0025] The gear four 24 and the gear five 25 are coaxially connected with a gear shaft two 282, and the gear shaft two 282 is rotatably arranged in the shell 1.
[0026] Gear 6 26 is coaxially connected to gear shaft 3 283, which is rotatably mounted inside housing 1. Gear shaft 1 281, gear shaft 282, gear shaft 3 283 and output shaft 28 are all rotatably mounted on housing 1 via bearings.
[0027] The housing 1 has a mounting base 12 on its side. The drive motor 3 is a shaded pole motor, and the stator of the drive motor 3 is fixedly mounted on the mounting base 12.
[0028] The specific working process of this utility model:
[0029] See Figure 3 First, connect the semi-circular key of the output shaft 28 of the geared motor to the semi-circular key of the stirring mechanism 4 of the snow melting machine. Then, connect the return spring 6 on the support column 13 to the snow melting machine body. Fit the limiting groove 71 of the positioning block 7 onto the outside of the limiting frustum 11, so that the entire geared motor can elastically swing under the action of the limiting groove 71 and the return spring 6. (See...) Figure 1 and Figure 2 The drive motor 3 is started, and the drive motor 3 drives the output shaft 28 to rotate through helical gear 1 21, helical gear 22, gear 3 23, gear 4 24, gear 5 25, gear 6 26 and gear 7 27, reducing the speed of 2200 r / min from the drive motor 3 to 40 r / min from the output shaft 28. Finally, the torque is transmitted to the stirring mechanism 4 through the output shaft 28 to stir the slurry.
[0030] At this time, the cooling fan 5 at the other end of the drive motor 3 rotates, carrying away the heat generated by the drive motor 3. The cooling fan 5 dissipates heat from the drive motor 3, preventing overheating and ensuring the normal operation of the drive motor 3.
[0031] When the drive motor 3 starts or the resistance of the slurry increases, causing the load on the drive motor 3 to suddenly become too large, the housing 1 swings in the limiting groove 71 to buffer the geared motor, and the reset spring 6 restores the geared motor to normal working condition, thus avoiding overload of the drive motor 3 and further improving the stability of the geared motor operation.
[0032] Both helical gear 1 (21) and helical gear 2 (22) are made of plastic, especially nylon. On the one hand, helical gears have higher transmission efficiency and longer service life. When the geared motor is overloaded, the damage to the plastic gears can protect the drive motor 3 and downstream equipment from overload. On the other hand, the use of metal materials is reduced, making the geared motor low in cost, lightweight and compact.
[0033] Gear shaft one 281, gear shaft two 282 and gear shaft three 283 are connected with corresponding gears by hydraulic pressing, which is more convenient to process, saves the use of metal material compared with one-time forming; high-temperature lubricating grease is used inside the speed reducer to replace machine oil for lubrication, so that the sealing of the speed reducer is better and oil leakage is less likely; the speed reducer adopts sealed silent high-speed bearing, prolonging the service life of the bearing and eliminating the need for separate lubrication of the bearing; the output shaft 28 is provided with an internal oil seal 8, so that the output shaft 28 of the speed reducer has better sealing.
[0034] The technical features not described in the utility model can be realized by or using the prior art, which will not be described here again, of course, the above description is not a limitation of the utility model, the utility model is also not limited to the above examples, the changes, modifications, additions or replacements made by the ordinary skilled in the art within the essential scope of the utility model should also belong to the protection scope of the utility model.
