Description

Technical Field

[0001] The utility model relates to the technical field of reduction motors, in particular to a three-axis output reduction motor. Background Art

[0002] The reduction motor is composed of a main drive motor and a reduction gearbox. During the high-speed operation of the reduction motor, a relatively "violent" movement occurs in the gearbox of the reduction motor. The heat generated instantly may not be too much, but the gearbox is generally closed, and the gearbox is generally close to the main drive motor. The main drive motor will also generate more heat when running at high speed. When the heat generated on the side adjacent to the gearbox is dissipated outward, the heat generated by the gearbox will produce invisible heat dissipation "suppression", resulting in "obstruction" in the outward heat dissipation of the main drive motor. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a three-axis output reduction motor, thereby reducing the thickness of the reduction combination box, and at the same time isolating the heat generated by the transmission between the main gear plate and the auxiliary gear outside the output detection box, avoiding excessive "suppression" of the heat dissipation of the motor body.

[0004] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0005] The utility model provides a three-axis output reduction motor, including a motor and a main drive shaft of the motor, wherein an output detection box and a reduction combination box are fixedly installed at the position of the main drive shaft. The output detection box is located between the motor and the reduction combination box, and the main drive shaft movably passes through the output detection box. A grating gear installed on the main drive shaft is arranged in the output detection box, and the output detection box is provided with a photoelectric detection switch for sensing and monitoring the rotation rate of the grating gear. A main toothed disc is installed at the side end portion of the main drive shaft beyond the output detection box. A plurality of secondary shafts are installed between the output detection boxes, and each secondary shaft is provided with a secondary gear meshing with the main toothed disc. One end of the secondary shaft movably passes through the reduction combination box, and a linkage output structure is arranged at the side end portion of the secondary shaft beyond the reduction combination box.

[0006] As a preferred technical solution of the reduction motor in the utility model: the grating gear is provided with a plurality of evenly distributed grating teeth, and the grating gear rotates synchronously with the main driving shaft. A detector installation slot for installing a photoelectric detection switch is provided on the side of the output detection box.

[0007] As a preferred technical solution for the reduction motor in the utility model: the output detection box is provided with a main through slot, the main drive shaft movably passes through the main through slot, and a main bearing for supporting the rotation of the main drive shaft is installed at the position of the main through slot.

[0008] As a preferred technical solution of the reduction motor in the utility model: the side end surface of the output detection box is provided with a plurality of secondary blind grooves matched with the side end of the secondary shaft rod, the inner side of the reduction combination box is provided with an inner side protrusion, the inner side protrusion is provided with an inner side groove, an end side blind groove connected with the inner side groove, and a plurality of secondary through grooves connected with the inner side groove. The side end of the main drive shaft is matched and installed at the position of the end side blind groove. The other side end of the secondary shaft rod movably passes through the secondary through groove, and a secondary bearing for supporting the rotation of the secondary shaft rod is installed at the position of the secondary through groove.

[0009] As a preferred technical solution for the reduction motor in the utility model: the sizes of the secondary gears installed on the plurality of secondary shafts are the same.

[0010] As a preferred technical solution of the reduction motor in the utility model: an outer shaft groove is opened on the outer side of the reduction combination box, and the linkage output structure is fixedly installed at the side end of the secondary shaft rod extending into the outer shaft groove.

[0011] Compared with the existing technology, the beneficial effects of the utility model are:

A grating gear and a photoelectric detection switch that cooperate with each other are arranged in the output detection box. The main drive shaft is more stably supported by the main bearing in the output detection box. The reduction combination box is fixedly installed on the periphery of the output detection box. The reduction combination box only needs to provide fixed support for the secondary shaft rod with a shorter length, thereby reducing the thickness of the reduction combination box. At the same time, the heat generated by the transmission between the main gear plate and the secondary gear is isolated outside the output detection box, thereby avoiding excessive "suppression" of the heat dissipation of the motor body.
