Abstract
The utility model discloses a duplex bevel gear driving device, comprising a casing. The utility model is characterized in that the casing comprises an input end and an output end; a small bevel gear is rotatingly disposed in the input end; a large bevel gear engaged with the small bevel gear is disposed in the output end; a drive hollow shaft is linked in the large bevel gear. The utility model has advantages of large transmission ratio and economical cost.
Description
Technical field
The utility model relates to a kind of drive unit, specifically is meant a kind of duplex umbrella gear drive unit.
Background technique
The gate valve of existing electronic control is provided with the drive unit of valve rod, comes actuate valve stem to rotate lifting, thus the opening and closing of control gate valve.But the drive unit velocity ratio of existing valve rod is less, therefore requires the model of input end motor big, cost height, economic inadequately.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming and defect that prior art exists, and a kind of velocity ratio is big, a kind of duplex umbrella gear drive unit of cost economy and provide.
For achieving the above object, the technical solution of the utility model is to include casing, this casing includes input end and output terminal, the rotatable bevel pinion that is provided with in the described input end, be provided with the large bevel gear of bevel pinion engagement driving in the described output terminal, be linkedly set with the driving hollow shaft in this large bevel gear.
The below that further setting is the relative output terminal of described casing is set with connecting base, supports being provided with thrust ball bearing between this connecting base and large bevel gear and the driving hollow shaft.
Between the input end inwall that further setting is described bevel pinion and casing the rotatable setting that radial ball bearing constitutes bevel pinion is set.
The novel advantage of this use is: by at input end bevel pinion is set, output terminal is provided with large bevel gear, two independent umbrella gear are coupled together, velocity ratio is increased, thereby reduced the moment of input end, also just reduced the motor model of input end, saved cost, practical more economically.
Below in conjunction with specification drawings and specific embodiments the utility model is done further introduction.
Description of drawings
Fig. 1 the utility model embodiment structure sectional view;
Fig. 2 the utility model embodiment plan view.
Embodiment
Embodiment of the present utility model shown in Fig. 1-2, include casing 1, this casing includes and is used for and input the motor input end 11 and the output terminal 12 that are connected, the rotatable bevel pinion 2 that is provided with in the described input end 11, the mode that described input motor driving bevel pinion rotates is well known to those skilled in the art, give unnecessary details no longer in detail at this place, be provided with the large bevel gear 3 of bevel pinion 2 engagement driving in the described output terminal 12, be linkedly set with in this large bevel gear 3 and drive hollow shaft 31, this drives hollow shaft 31 and can link with the valve rod of gate valve, thus the actuate valve stem lifting.
The below of the described casing 1 relative output terminal 12 of present embodiment is set with connecting base 13, supports being provided with thrust ball bearing 32 between this connecting base 13 and large bevel gear 3 and the driving hollow shaft 31.In addition, between input end 11 inwalls of described bevel pinion 2 and casing 1 radial ball bearing 21 is set, constitutes the rotatable setting of bevel pinion 2.
