Example Embodiment

[0022] Example 1: Such as figure 1 , figure 2 In the embodiment shown, a speed reduction transmission device includes a box body 1, a power motor 2. The box body is provided with an upper worm 3, a lower worm 4, and a transmission worm wheel 5. The upper worm and the lower worm All have one end out of the box, the end of the upper worm out of the box and the end of the lower worm out of the box are on the same side of the box, the upper worm and the lower worm are respectively provided with an upper gear 6, The lower gear 7, the upper gear is coaxial with the upper worm, and the lower gear is coaxial with the lower worm. The end of the lower worm protruding out of the box is connected to the power motor, and the upper worm and the lower worm are both matched and connected with the transmission worm. The transmission worm gear is arranged on a worm gear shaft 8, the upper gear and the lower gear are outside the box body, and the upper gear meshes with the lower gear. Any reduce...

Example Embodiment

[0028] Embodiment 2: The basic structure and implementation of this embodiment are the same as those of Embodiment 1, and the difference lies in: image 3 , 4 As shown in the figure, the spiral teeth of the lower worm are provided with a continuous spiral groove 18 arranged along the spiral direction of the spiral teeth of the lower worm, and the spiral groove is opened at the tooth top of the spiral teeth of the lower worm.

[0029] The gear teeth 23 of the transmission worm gear are provided with slightly variable elastic through grooves 19, and the slightly variable elastic through grooves are opened at the tops of the gear teeth where they are located, and the gear teeth of the transmission worm wheel are provided with deformation protection holes 20 , The deformation protection hole is communicated with the bottom of the slightly variable elastic through groove.

[0030] In the previous scheme, the dynamic adjustment function of the disc spring and the sliding sleeve can elimin...

Example Embodiment

[0031] Embodiment 3: The basic structure and implementation of this embodiment are the same as those in Embodiment 1, the difference lies in that image 3 , Figure 5 As shown in the above, the transmission worm wheel includes a worm gear body, a number of complete teeth 21, and a number of grooved teeth 22. The complete teeth and the grooved teeth are arranged at intervals on the side edge of the worm wheel body, and the grooved teeth are provided There are slightly variable elastic through grooves, the said slightly variable elastic through grooves are open on the tooth tops of the gear teeth where they are located; when the complete teeth mesh with the upper worm, the lower worm meshes with the grooved teeth, and when the complete tooth meshes with the lower worm When, the upper worm meshes with the grooved teeth. The grooved tooth is provided with a deformation protection hole, and the deformation protection hole is communicated with the groove bottom of the slightly variab...

Abstract

The invention discloses a speed reduction transmission device. By means of the speed reduction transmission device, speed reduction transmission can be effectively carried out, the overall structure is reasonable, the matching accuracy is high, running is stable, and it can be guaranteed that the instant position fluctuations of all structures are small and errors and accumulative errors are fewer, and the transmission accuracy can be effectively guaranteed. The speed reduction transmission device comprises a tank body, a power motor, an upper worm, a lower worm and a transmission worm gear; and the upper worm and the lower worm are provided with an upper gear and a lower gear respectively, the lower worm is connected with the power motor, the upper worm and the lower worm are connected with the transmission worm gear in a matched manner, the upper gear and the lower gear are located outside the tank body, and the upper gear is meshed with the lower gear. Helical teeth of the upper worm and helical teeth of the lower worm are the same in tooth shape, the lower worm gear comprises a worm gear shaft and a sliding sleeve, the helical teeth of the lower worm are located on the sliding sleeve, and the sliding sleeve is in sliding connection with the worm shaft; and the worm shaft is provided with a limiting neck, a compensation gap is reserved between one end of the sliding sleeve and the limiting neck, and the other end of the sliding sleeve is pressed by a self-adjusting spring.

Description

technical field [0001] The invention belongs to the technical field of worm gear precision transmission, and in particular relates to a reduction transmission device. Background technique [0002] It is very important to control the transmission error in precision transmission. In practice, no matter how high the precision of the reducer used is, it is impossible to completely eliminate the transmission error. It can only make the error as small as possible under certain conditions. Worm gear reducer is a commonly used type of reducer. Although the current worm gear reducer can improve the transmission accuracy from the aspects of improving manufacturing accuracy, improving assembly accuracy, and rationality, it is not suitable for local wear and vibration. There are still obvious deficiencies in the control of the coordination transmission error and the elimination of the accumulated error. Contents of the invention [0003] In order to overcome the deficiencies in the p...
