In order to overcome the above shortcomings, the purpose of this creation is to provide a high reduction ratio worm gear reducer, which, with a good structural configuration, has to be optimized in a limited casing to obtain a compact size and maintain good output. Power worm gear reducer.

Another purpose of this creation is to provide a high reduction ratio worm gear reducer, its power output is quite stable, vibration and noise are reduced, so that it has a wide range of applications, and it is suitable for any machinery that requires a high reduction ratio transmission.

Another purpose of this creation is to provide a worm gear reducer with a high reduction ratio, which has a stable structure, reduces the occurrence of failures or damages, and effectively increases the service life.

In order to achieve the above objectives, the technical solution adopted in this creation is to provide a high reduction ratio worm gear reducer, which includes a gear box and a power box.

The gear box is provided with a worm, the worm meshes with a worm wheel, the shaft center of the worm wheel is penetrated with an output shaft, and one end of the worm is provided with an input gear; the power box device is on the input gear side of the gear box, the The power box is provided with a transmission shaft, and the end of the transmission shaft is provided with an output gear, so that the output gear is meshed with the input gear; Wherein, the output gear and the input gear are helical gears meshing, and the number of teeth of the output gear is less than that of the input gear, so that the output gear can output high-speed and stable rotation power. The input gear generates deceleration, and then passes through the worm and the worm gear. And achieve the power output of the output shaft with a high reduction ratio.

In the foregoing structure, ball bearings are sleeved at both ends of the worm to maintain stable rotation.

In addition, the power box is a brushless motor, and ball bearings are sleeved at both ends of the transmission shaft in the power box to maintain stable rotation.

The preferred embodiments of the creation will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the creation can be more easily understood by those skilled in the art, so as to make a clearer and clearer definition of the protection scope of the creation.

Please refer to FIG. 1 to FIG. 3, a high reduction ratio worm gear reducer provided by this invention mainly includes a gear box 100 and a power box 200.

The gear box 100 is provided with a worm 110 which meshes with a worm wheel 120. The shaft of the worm wheel 120 passes through an output shaft 130 which is connected to other equipment to provide power.

With the arrangement of the worm wheel 120 and the worm 110, it is necessary to provide the required power of the other equipment with low rotation speed and high torque.

An input gear 140 is provided at one end of the worm 110, and the input gear 140 is connected to the power box 200 to input power.

The power box 200 is installed on the side of the input gear 140 of the gear box 100. The power box 200 is provided with a transmission shaft 210. The end of the transmission shaft 210 is provided with an output gear 220, so that the output gear 220 meshes with the input gear 140 Above, the power generated by the power box 200 is transmitted to the input gear 140 via the output gear 220, and the gear box 100 is used for deceleration.

In order to achieve the function of creating a high reduction ratio, the output gear 220 and the input gear 140 are meshed with helical gears. With the characteristics of the helical gear, the advantages of uniform transmission, low noise, and high-speed rotation can be obtained. The gear 220 has fewer teeth than the input gear 140.

Utilizing the configuration of the output gear 220 and the input gear 140, the power output by the power box 200 can be output by the output gear 220 in a high-speed and stable rotation, and then the input gear 140 is greatly decelerated, and then the worm 110, the worm 110, the The deceleration of the worm gear 120 finally achieves the power output of the output shaft 130 with a high reduction ratio.

In order to maintain good stability, ball bearings 150 are sleeved at both ends of the worm 110, so that the worm 110 can maintain stability when it rotates at a high speed.

The power box 200 is a motor, and more precisely, a brushless motor. With the brushless motor, the volume can be further reduced and the stability during operation can be maintained.

Of course, the two ends of the transmission shaft 210 are also sleeved with ball bearings 230, so that the transmission shaft 210 can still maintain stability when rotating at a high speed.
