Abstract
The utility model relates to a transmission device using flexible members, in particular to a transfer case for a crane, which comprises a case body and a case cover. An input shaft, an output shaft and an input gear are arranged in the same axis in the case body. A first driving shaft and a second driving shaft are arranged on a lateral side of the axis of the input shaft and the output shaft. A first driving gear and a second driving gear are arranged on the first driving shaft and the second driving shaft. The input gear is meshed with the second driving gear, and the second driving gear is meshed with the first driving gear. A bearing is respectively arranged at two ends of each shaft. A coupling device is respectively arranged at end portions of the input shaft, the output shaft and the first driving shaft. The transfer case changes a traditional vertical structure into a horizontal structure, obtains installation on large-scale machinery which can not use vertical transfer cases, replaces traditional speed reducers, and reduces total weight of the large-scale machinery.
Description
Technical field
The utility model relates to a kind of transmission device that uses flexible original paper, relates in particular to a kind of transfer case that is used on the hoist.
Background technique
Transfer case, the power with motor carries out assigned unit exactly, can output power to rear axle, before perhaps outputing to simultaneously/rear axle.Traditional transfer case structure is vertical structure; As shown in Figure 3, promptly the second output main shaft directly over input, the output shaft place central axis or under, the structure that transfer case is vertical like this; Cause big machinery such as the hoist etc. of practical lateral velocity variation case and can not adopt transfer case to carry out power distribution; Can only rely on retarder to slow down, and retarder is generally cast iron or steel plate is processed, has increased the weight of the overall weight of hoist.
The model utility content
The utility model technical problem to be solved is installed a kind of when a power input, a plurality of power outputs of realization, the transfer case that again the hoist overall weight is alleviated simultaneously for replacing traditional retarder on the hoist.
The purpose of the utility model mainly is achieved through following proposal: a kind of transfer case; Comprise casing, case lid; Be provided with the input shaft, output shaft and the input gear that are on the same axis in the said casing; The side of described input shaft and output shaft place axis is provided with first live axle and second live axle; Described first live axle and second live axle are provided with first actuation gear and second actuation gear, described input gear and the engagement of second actuation gear, described second actuation gear and the engagement of first actuation gear; Two ends head at each is provided with bearing, and the end of described input shaft, output shaft and first live axle is provided with coupling.
Adopt this programme; Side at input shaft and output shaft place axis is provided with first live axle and second live axle; Rather than above or below input shaft and output shaft place axis, first live axle and second live axle being set, the structure of transfer case is horizontal type like this, therefore on the big machinery that can not use vertical transfer case, just can realize installing; Replace traditional retarder, alleviated the overall weight of big machinery.Input gear and the engagement of second actuation gear; Described second actuation gear and the engagement of first actuation gear; Like this after the input gear rotates; Drive second actuation gear and rotate, meanwhile first actuation gear with the engagement of second actuation gear also rotates simultaneously, can realize transmission and distribution to power through the bearing drive output shaft of each two ends and the coupling of first driveshaft end like this.
As preferably, the bearing that the termination, two ends of described input shaft, output shaft and first live axle is provided with is a ball bearing, and the bearing of the termination, two ends of described second live axle is a needle bearing.Input shaft, output shaft and first live axle are the major impetus output shaft, so the bearing of their termination, two ends is ball bearing, can bear bigger load.And second live axle is owing to be between the input shaft and first live axle, and its radial space is restricted, and therefore adopts needle bearing.
As preferably, described input gear is connected through duplicate gear with output shaft.Adopt duplicate gear to connect between input gear and the output shaft, can better more effective transferring power.
As preferably, the parallel axes of the axis of described first live axle and second live axle and input shaft, output shaft.Adopt this programme, three axis-parallel can make three intermeshing better effects if of the gear on the axial location like this.
As preferably, the material of described casing and case lid is an aluminum alloy material.Aluminum alloy material is little compared to iron and steel density, be difficult for getting rusty, so the material of casing and case lid adopts aluminum alloy, the weight of transfer case alleviated greatly, thereby alleviate the overall weight of hoist.
Therefore; The beneficial effect of the utility model is: changed the traditional vertical structure of transfer case, the structure that makes transfer case is the horizontal type structure, on the big machinery that can not use vertical transfer case, realizes installing; Replace traditional retarder, alleviated the overall weight of big machinery.
