Problems solved by technology

The methods of reducing the backlash mainly include: adjusting the center distance method, the method of contacting the hairspring, and the two-piece gear control backlash. Among them, the method of double-piece gear control backlash is difficult to adjust and the backlash increases after a long period of use. Then adjust; the disadvantage of the contact hairspring method is that the gears in the transmission chain can only rotate a limited angle; and the current adjustment center distance method basically adopts the design and processing of the gear shaft as an eccentric shaft. When installing, adjust the angle of the supporting part. The eccentric shaft changes the eccentric distance to control the backlash, but this method is difficult to guarantee the accuracy of the center distance and backlash after long-term use

Embodiment Construction

[0010] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0011] combine figure 1 and figure 2 , the composition of the carriage mechanism of the present invention that reduces backlash in gear transmission includes a motor 1, a reducer 2, a bracket 3, a pressing plate 4, a pressing plate 5, a carriage 6, a guide rod 7, a spring 8, a gear 9, a gear 10, Gear shaft 11, bolt group 12, bolt group 13, bolt group 14 and screw group 15. Install a gear 10 on the gear shaft 11 through a bearing, and the gear shaft 11 is installed on the bracket 3 through a bolt group 12, so that the gear 10 has only one degree of freedom of rotation around the gear shaft 11; another gear 9 meshing with the gear 10 is installed On the output shaft of the reducer 2, the rotation of the output of the motor 1 can make the gear 9 rotate, and the reducer 2 is installed on the carriage 6 through the screw group 15; Process the groove, respectively f...

Abstract

The invention provides a sliding frame mechanism capable of reducing the transmission idling of gears, comprising a pair mutually engaged gears, namely a large gear and a small gear. A gear shaft of the small gear is mounted on a sliding frame which is glidingly mounted on a support and has only one motion degree of freedom, the gear shaft of the small gear is connected with a reducer which is connected with a motor, and a compression spring is arranged between the sliding frame and the support. The invention provides a new method which is safe and reliable and is convenient to mount gears, reduces the side clearance of the gears and adopts the compression spring so that a gear and another engaged gear which are mounted on the sliding frame can keep the minimum center distance.

Description

(1) Technical field [0001] The invention relates to a carriage mechanism for reducing the backlash of gear transmission, in particular to a mechanism composed of a spring and a carriage for reducing the backlash of gear transmission connected to the output shaft of a reducer. (2) Background technology [0002] Ideally, due to manufacturing and installation errors, a pair of gears that mesh with each other must have a minimum backlash to compensate for thermal deformation and provide a space for storing lubricating oil. Therefore, a reasonable gap is specified according to the usage situation. The methods of reducing the backlash mainly include: adjusting the center distance method, the method of contacting the hairspring, and the two-piece gear control backlash. Among them, the method of double-piece gear control backlash is difficult to adjust and the backlash increases after a long period of use. Then adjust; the disadvantage of the contact hairspring method is that the g...
