Abstract
The utility model discloses a kind of device for driving electric gourd drum, it includes wallboard, is fixed on the motor on wallboard, reel and the drive sleeve being fixed on reel its inwall, third-level planetary reduction gear is disposed between motor and reel, the third-level planetary reduction gear includes reduction case, sun wheel shaft, third-level planetary frame, third-level planetary frame is fixed on wallboard, its output shaft of motor is connected by shaft coupling with the left end of sun wheel shaft, is coupled between drive sleeve and reduction case by inside and outside spline；Shaft coupling is yielding coupling.Drive sleeve is set up by the inwall in reel, the drive sleeve couples with the reduction case of third-level planetary reduction gear in inside and outside spline, so can fast toward assembling third-level planetary reduction gear on reel, during maintenance activity third-level planetary reduction gear together with motor can be realized from drive sleeve it is whole tear open it is self-contained.
Description
【Technical field】
A kind of device for driving electric gourd drum is the utility model is related to, belongs to hoisting machinery technical field.
【Background technology】
The drum driving apparatus being now widely used on electric block, its planetary reduction gear are typically loaded on inside reel
, due to its narrow space of reel, cause planetary reduction gear assembling cumbersome, and find that detachable maintaining is difficult, has during use
In consideration of it, real have improvement necessary.
【Utility model content】
The problem of to overcome existing electric gourd drum drive device disassembly efficiency low, the purpose of this utility model is
A kind of device for the driving electric gourd drum that third-level planetary reduction gear can be quickly dismounted from reel is provided.
Therefore, the utility model employs following technical scheme：
A kind of device for driving electric gourd drum, including wallboard, the motor being fixed on wallboard, reel, are driving
Dynamic that third-level planetary reduction gear is disposed between motor and reel, the third-level planetary reduction gear includes reduction case, sun gear
Axle, third-level planetary frame, the third-level planetary frame are fixed on wallboard, and its output shaft of motor passes through shaft coupling and sun wheel shaft
Left end be connected, its improvement is：Also include the drive sleeve being fixed on reel its inwall, the drive sleeve and reduction-gear housing
Coupled between body by inside and outside spline；The shaft coupling is yielding coupling.
Compared with prior art, the utility model has the advantages that：
Drive sleeve is set up by the inwall in reel, the reduction case of the drive sleeve and third-level planetary reduction gear in it is interior,
External splines couples, so can fast toward assembling third-level planetary reduction gear on reel, during maintenance activity third-level planetary reduction gear together with
Motor can be realized from drive sleeve it is whole tear open it is self-contained；After shaft coupling uses yielding coupling, sun wheel shaft and driving can be reduced
The axiality requirement of the output between centers of motor.
【Brief description of the drawings】
Fig. 1 is structural representation of the present utility model.
【Embodiment】
Make a detailed description to specific embodiment of the present utility model below in conjunction with the accompanying drawings.
A kind of device for driving electric gourd drum, including wallboard B, the motor M being fixed on wallboard B, reel 6,
It is disposed with third-level planetary reduction gear between motor M and reel 6, third-level planetary reduction gear includes reduction case 41, too
Positive wheel shaft H, third-level planetary frame 3, third-level planetary frame 3 are fixed on wallboard B, motor M its output shaft M1 by shaft coupling 7 with
Sun wheel shaft H left end is connected, and its improvement is：Also include the drive sleeve 5 being fixed on reel 6 its inwall, drive sleeve 5 with
Coupled between reduction case 41 by inside and outside spline；Shaft coupling 7 is yielding coupling.
In the present embodiment, drive sleeve 5 is directly welded on the inwall of reel 6.
Third-level planetary reduction gear mainly by reduction case 41, decelerator case lid 42, sun wheel shaft H, be fixedly arranged on sun gear
I level sun gears H1 on axle H, it is set with the II level sun gear H2 on sun wheel shaft H and III level sun gear H3, equipped with I levels
The primary planet carrier 1 of planetary gear 10, the secondary planet frame 2 equipped with II levels planetary gear 20 and the three-level equipped with III level planetary gear 30
Planet carrier 3 forms.
Third-level planetary frame 3 stretches out from reduction case 41 and is fixed on by fastening bolt on wallboard B, and third-level planetary
Bearing F2 is housed between frame 3 and reduction case 41；Bearing F1, Yi Ji are housed between sun wheel shaft H and third-level planetary frame 3
Bearing F1 is also equipped between sun wheel shaft H and decelerator case lid 42, and sun wheel shaft H left end passes through shaft coupling 7 and driving electricity
Machine M output shaft M1 connections, II level sun gears H2, III level sun gear H3 are arranged in an I level sun gears H1 left side from right-to-left successively
Side；Primary planet carrier 1, secondary planet frame 2 in reduction case 41 respectively with II level sun gears H2, III level sun gear
H3 is fixedly connected；I level sun gear H1, II level sun gears H2, III level sun gear H3 engage I levels planetary gear 10, II level planets respectively
Wheel 20, III level planetary gear 30, III level planetary gear 30 are meshed with taking shape in the gear ring portion 410 of the inwall of reduction case 41.
Wherein, sun wheel shaft H and I level sun gears H1, which is integrally machined, forms；I levels planetary gear 10 is evenly distributed with three, II
Level planetary gear 20 is evenly distributed with three；III level planetary gear 30, which is centrosymmetric, is distributed with four.
Its output shaft of motor M M1 provides high speed low torque power direct drive sun wheel shaft H, is subtracted by third-level planetary
For fast device after deceleration, the low speed and large torque of output passes to drive sleeve 5, with the band smooth rotation of movable reel 6.
