Abstract
The utility model discloses a forward/reverse-rotation driving device, which comprises an enclosed box body, a pair of bevel gear wheels and a pair of bevel pinions, wherein, the pair of bevel gear wheels and the pair of bevel pinions are mutually engaged in an accommodating cavity of the box body; the bevel gear wheels are arranged at the upper end the lower ends of the accommodating cavity respectively; the bevel pinions are arranged at the left and the right ends of the accommodating cavity; the bevel gear wheel arranged at the upper end of the accommodating cavity, and the bevel gear wheel arranged at the lower end of the accommodating cavity are respectively connected with a through shaft and a hollow shaft; and the hollow shaft is sleeved on the through shaft and in fit with the through shaft through a rolling bearing. The utility model has following benefits: the forward/reverse-rotation driving device adopts the driving structure formed by the two pairs of bevel gears, the through shaft and the hollow shaft to uniquely realize the single-way input of the through shaft, as well as the coaxial bidirectional output of the hollow shaft. The forward/reverse-rotation driving device has the advantages of compact and reasonable structure, small volume, light weight, and installation and use facilitation, and furthermore, the device can greatly improve the working efficiency and the mixing quality of a deep-cement-mixing pile when being applied to the deep-cement-mixing pile.
Description
Technical field:
The utility model relates to the mechanical transmissioning technology field, especially relates to a kind of transmission device that is made of gear and transmission shaft.
Background technique:
Deep water earth stirring pile mostly is unidirectional rotation at present, and it is insufficient to exist cement and soil to stir in actual use, and is fused inhomogeneous, even generates the phenomenon of earth piece, therefore need improve its transmission device.
The model utility content:
The purpose of this utility model is to provide a kind of clockwise and anticlockwise transmission device of realizing unidirectional input, two-way output, and it has characteristics rational in infrastructure, simple to operate, high working efficiency.
For achieving the above object, clockwise and anticlockwise transmission device of the present utility model has the casing of a sealing, be provided with two pairs of intermeshing bevel gear wheels and bevel pinion in the holding cavity of casing, wherein, bevel gear wheel lays respectively at holding cavity two ends up and down, and bevel pinion then is positioned at two ends, the holding cavity left and right sides, and the bevel gear wheel that is positioned at the holding cavity upper end connects with axis and hollow shaft respectively with the bevel gear wheel that is positioned at the holding cavity lower end, hollow shaft sleeve is located on the axis, cooperates by rolling bearing between the two.
The beneficial effects of the utility model are: it adopts the drive mechanism of two pairs of bevel gears and an axis and a hollow shaft, realized the unidirectional input of axis dexterously, the concentric two-way output of axis and hollow shaft, compact structure is reasonable, volume is little, in light weight, be convenient to install and use, after it is used on the deep water earth stirring pile, can improve the working efficiency and the mixing quality of deep water earth stirring pile greatly.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a whole sectional structure chart of the present utility model.
Embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See shown in Figure 1: clockwise and anticlockwise transmission device of the present utility model has the casing 10 of a sealing, be provided with two pairs of intermeshing bevel gear wheels 21 in the holding cavity 11 of casing 10,22 and bevel pinion 23,24, wherein, bevel gear wheel 21 and 22 lays respectively at holding cavity, and about in the of 11 two ends, and bevel pinion 23 and 24 are positioned at two ends, holding cavity 11 left and right sides, and four bevel gears (21～24) are " mouth " word shape and distribute; The bevel gear wheel 22 that is positioned at the bevel gear wheel 21 of holding cavity 11 upper ends and is positioned at holding cavity 11 lower ends respectively with axis 31 and hollow shaft 32 key connecting, hollow shaft 32 is set on the axis 31, cooperates by rolling bearing between the two.
When axis 31 turns clockwise, driving bevel gear wheel 21 turns clockwise, bevel gear wheel 21 then drives another bevel gear wheel 22 by bevel pinion 23 and 24 and is rotated counterclockwise, when bevel gear wheel 22 is rotated counterclockwise, also be rotated counterclockwise with the hollow shaft 32 of its key joint, thereby realize the purpose of unidirectional input (axis 31 input), two-way output (axis 31 and hollow shaft 32 concentric two-way rotations).
