Abstract

The novel planetary reduction gearbox comprises a fixed flange and an output flange, one side of the fixed flange is fixed to a power mechanism, the other side of the fixed flange is connected with the output flange through a bearing, and a coupler is installed in the fixed flange through a bearing; a fixed gear ring, an output gear ring and a planetary gear mechanism are arranged in the output flange, the fixed gear ring is fixed on the fixed flange, the output gear ring is fixed on the output flange, the fixed gear ring and the output gear ring are arranged side by side and have a tooth number difference, the planetary gear mechanism comprises a sun gear shaft and a planetary gear, and the sun gear shaft is connected with the coupler. The planetary gear is meshed with the fixed gear ring and the output gear ring at the same time; compared with the prior art, the two split type gear rings are adopted to replace a multi-stage gear ring in the background technology, the machining difficulty can be effectively lowered, the number of parts can be reduced, meanwhile, a large speed ratio can be kept on the basis that a transmission chain is shortened, and the gear ring has the advantages of being novel in structure, efficient in transmission, easy and convenient to manufacture, stable, reliable and the like.

Example Embodiment

[0017] In this embodiment, the installation of the sun gear shaft 10 adopts the floating method, and the radial direction is limited by the planetary gear 8 and the planet carrier 12; One side is limited by the rear stopper 11 installed on the output flange 4 . The left and right sides of the middle hole of the planet carrier 12 are provided with blocks 9 , the left block 9 is against the planet carrier 12 and the coupling 14 , and the right block 9 is against the planet carrier 12 and the output flange 4 . During this time, the axial movement of the planet carrier 12 is restricted by the stopper 9 .
[0018] In this embodiment, a sealing member 2 is also provided at the connection between the output flange 4 and the fixed flange 1 for oil sealing, and the sealing member 2 is made of nylon sheet.
[0019] The power transmission method of this embodiment is as follows: the power is input through the motor end claw 15 and the input claw 17, and is transmitted to the sun gear shaft 10, and after the sun gear shaft 10 and the planetary gear 8, it is transmitted to the fixed ring gear 5 and the output gear. Ring 7, the number of teeth of the fixed ring gear 5 and the output ring gear 7 are different, and the fixed ring gear 5 is fixed, so the planet carrier 12 and the planet gear 8 rotate around the sun gear shaft 10, so that the power drives the output flange 4 through the output ring gear 7 Rotate to output the power to the output spline sleeve 6 .
[0020] The above embodiments are only used to illustrate the concept of the present invention, but not to limit the protection of the rights of the present invention. Any non-substantial changes to the present invention by using this concept should fall within the protection scope of the present invention.
[0016] The outside of the output flange 4 is connected with a spline connection sleeve through a spline, and is connected with an external actuator through the spline connection sleeve, for example, the spline connection sleeve is connected with the drum of the hoisting equipment.
