Abstract
The utility model relates to a driving apparatus for a concrete mixer axis, which is composed of a motor and a planetary gear drive mechanism, wherein, the planetary gear drive mechanism comprises a box body, an internal gear fixedly connected with the internal wall of the box body, a sun gear axis fixed with a motor axis, and a planetary gear train meshing between the internal gear and the sun gear axis. A planetary carrier in the planetary gear train is used to fix with the mixer axis, and drives the rotation of the mixer axis. The utility model has the advantages of compact structure, high transmission efficiency, and convenient installation and maintenance, and is especially suitable for driving a forced concrete mixer with the single horizontal axis.
Description
The utility model relates to a kind of drive unit of concrete mixer.What be particularly related to is a kind of drive unit of single horizontal axis forced concrete mixer.
What the drive unit of existing single horizontal axis forced concrete mixer was common has two kinds: a kind of is to be made of motor and common cylinder gear drive decelerator, and another kind is to be made of motor and plane-generated double enveloping worm reducer.The former shortcoming is that volume is big, cost is high, transmission efficiency is low, and the life-span is also short; The latter's deficiency is the assembling and setting complexity, and interchangeability is poor, and twice-enveloping worm and wormwheel required precision height, manufacture difficulty are big, the cost height.Simultaneously, these two kinds of drive units all need to be connected with the stirring arbor by shaft coupling, make its transmission efficiency influenced.
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, provides that a kind of volume is little, transmission efficiency is high and the installation and maintenance drive unit of concrete mixer axle easily.
The drive unit of the concrete mixer axle of realization the purpose of this utility model is made up of motor and transmission mechanism, described transmission mechanism is a planetary gear mechanism, its formation comprises casing, be installed in internal gear on the cabinet wall, and affixed sun gear shaft of motor shaft and the epicyclic train between internal gear and sun gear shaft of being connected with a joggle, described epicyclic train comprises pinion frame and several uniform planetary gears that are arranged on the pinion frame, and this planetary gear meshes simultaneously with internal gear and sun gear shaft respectively.During work with the shaft Joint of pinion frame and concrete mixer, the power drive sun gear shaft of motor shaft rotates, sun gear shaft drives the epicyclic train that is meshed with it and rotates with respect to the internal gear that is fixed on the cabinet wall, both having driven pinion frame rotates, and, drive affixed with it stirring arbor and rotate by this pinion frame output torque.
Be the mixer that the satisfies various different models needs to its different speed ratios and moment of torsion, described planetary gear type transmission mechanism can adopt multi-stage serial connection to use, and use both has been connected the pinion frame of upper level with the sun gear shaft of next stage.
The working environment of considering mixer is more abominable; " card " changes the characteristics that cause overload operation easily; can between motor shaft and sun gear shaft, adopt a pulley transmission mechanism to give sun gear shaft with the transmission of power of motor shaft; when the generation excess load is unusual; then can eliminate, play overload protective function by belt " skidding ".
The utility model utilizes pinion frame directly to serve as power output shaft and can realize that the back of the body goes into formula and connect and drive its running with stirring arbor, need not to utilize the shaft coupling connection, and its compact conformation, volume are reduced; Transmission efficiency, bearing capacity and anti shock and vibration ability all are improved.Simultaneously also make its processing and manufacturing more easy, installation and maintenance are also more convenient.Use by simple multi-stage serial connection, different speed ratio and moments of torsion can be provided.Be applicable to and drive various concrete mixers.
Below in conjunction with embodiment and accompanying drawing the utility model is described further.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation of planetary gear mechanism
Fig. 3 is the A-A view of Fig. 2
As shown in Figure 1, the formation of present embodiment comprises motor 1, epicyclic transmission mechanism 2, adopts common mode to connect by pulley transmission mechanism 3; The structure of epicyclic transmission mechanism 2 is shown in Fig. 2,3, its formation comprises casing 4, is fixed in internal gear 6 on casing 4 inwalls with the affixed sun gear shaft 5 of belt gear 3 and with screw 21 and pin 22, epicyclic train is made of pinion frame 7, a plurality of uniform planetary gear 9 that is arranged on the pinion frame 7, the number of planetary gear 9 can optionally be provided with, be installed on the pinion frame by planet pin 10, needle roller 11, and mesh simultaneously with internal gear 6, sun gear shaft 5 and to be installed in the casing.It is affixed with stirring arbor 12 that pinion frame 7 can be adopted splined form.Power from motor shaft then rotates by driving sun gear shaft and driving the epicyclic train that is engaged with by sun gear shaft, is driven by its pinion frame output torque and stirs the arbor rotation.
What as can be seen from the figure, present embodiment provided is a kind of planetary gear mechanism that is made of three grades of serial connections.Wherein, the shared casing 14,15,16 of preceding two-stage is a sun gear shaft, and 17,18 is pinion frame.Install for convenient, can set up support 19 and bearing 20.
Claims (3)
1, a kind of drive unit of concrete mixer axle, form by motor and transmission mechanism, it is characterized in that described transmission mechanism is a planetary gear mechanism, its formation comprises casing, be installed in internal gear on the cabinet wall, and affixed sun gear shaft of motor shaft and the epicyclic train between internal gear and sun gear shaft of being connected with a joggle, described epicyclic train comprises pinion frame and several uniform planetary gears that are arranged on the pinion frame, and this planetary gear meshes simultaneously with internal gear and sun gear shaft respectively.
2, the drive unit of concrete mixer axle as claimed in claim 1 is characterized in that described planetary gear mechanism can be made of multi-stage serial connection.
