Abstract
The utility model provides a drive reducer for a crane. A gear shaft is arranged on two sides of the upper part of a frame through bearings; a hollow shaft is arranged on the two sides of the frame below the gear shaft through bearings; the hollow shaft is provided with a gear meshing with the gear shaft; the left side of the frame is connected with a side cover; an oil seal is used to seal the bearing of the side cover between the hollow shaft and the side cover; a hole on the right end of the hollow shaft is inside provided with a sealed end closure; one side of an oil sump below the frame is provided with a view window; the right side of the frame is provided with a step hollow disc around the gear shaft, a step on the gear shaft inside the hollow disc is inside provided with a planet carrier; two or three planet wheels are symmetrically arranged on the planet carrier in the step through a pin roll, a shaft housing and a pad; the outside of the planet wheel meshes with an inner ring gear on the inner wall of the hollow disc; and the inner side of the planet wheel meshes with a gear shaft of a motor. The utility model adopts the gear shaft of the motor to drive the gear shaft through the planet wheel and adopts the hollow shaft to drive the gear to output power. Moreover, the utility model has stable operation and low possibility of breaking up the gear.
Description
Technical field:
The utility model relates to hoist, and the hoist of installing on particularly a kind of suitable hoist and other operational outfit is with driving speed reducer.
Background technique:
The lifting speed reducer of installing on present hoist and other operational outfit, a kind of is soft tooth surface speed reducer, a kind of is three-in-one speed reducer, and mainly by a cover external gear pump transmission, volume is big for soft tooth surface speed reducer, consumptive material is many, working life is short, and three-in-one serial speed reducer is because in service back and forth frequent back and forth, stop or the instant impact that commutates big, the noise height easily breaks gear.
Summary of the invention:
The purpose of this utility model provides a kind of operating steadily, and is difficult for breaking gear, and noise is little, and the hoist of long service life is with driving speed reducer.
The technical solution of the utility model is finished as follows, it includes support, it is characterized in that: with Bearing Installation one rooted tooth wheel shaft is arranged in the upper part of the frame both sides, there is a hollow shaft support both sides below gear shaft with Bearing Installation, the engagement of gear and gear shaft is arranged on the hollow shaft, be connected with a side cover in the support left side, on the side cover bearing, be sealed with oil sealing between hollow shaft and the side cover, an end cover is installed in the right-hand member hole of hollow shaft, side at support bottom oil sump is provided with the perspective window, is that the center is provided with a hollow disk of stepped shape on the support right side with the gear shaft, a planet carrier is installed in step on the hollow disk inner gear shaft, on the planet carrier in step through bearing pin, axle sleeve and pad are symmetrically installed with 2-3 planet wheel, ring gear engagement on the planet wheel outside and the hollow disk inwall, the inboard and motor gear axle engagement of planet wheel.
The utility model, by hollow shaft driven gear outputting power, operates steadily by motor gear shaft driven gear axle at last by planet wheel, and noise is little, is difficult for breaking gear.
Description of drawings:
Fig. 1 is a side of the present utility model sectional structure schematic representation, and Fig. 2 is a Facad structure schematic representation of the present utility model.
Embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, the utility model is with bearing 2 and 14 a rooted tooth wheel shaft 3 to be installed in both sides, support 9 top, a hollow shaft 7 is installed with bearing 4 in both sides on the support below gear shaft, there is gear 8 to be meshed on the hollow shaft with gear shaft, in the support left side side cover 1 is installed, on bearing, be sealed with oil sealing 5 between side cover and the hollow shaft, the end cap 11 of a band seal ring 10 is installed in hollow shaft right-hand member hole.Side at support bottom oil sump is provided with perspective window 6, is that the center is provided with a hollow disk of stepped shape on the support right side with the gear shaft, a planet carrier 13 is installed on gear shaft in the interior step of hollow disk, be symmetrically installed with two or three planet wheels 16 through bearing pin 17 and axle sleeve 18 usefulness pads 19 in the topping bar of planet carrier, the planet wheel outside is meshed with ring gear 12 on the support, and planet wheel is inboard to be meshed with motor gear axle 15.The utility model operates steadily so have owing to adopt the planet wheel driving gearshaft and hollow shaft and gear mesh thereof do work outward, can not break gear, and the life-span of speed reducer is greatly prolonged, and the noise that produces during work is little.
