Abstract

The utility model relates to the technical field of an open-close machine, and in particular provides a screw type open-close machine which is especially suitable for opening or closing a large-stroke gate. The screw type open-close machine comprises a motor, a speed reducer and a screw which is connected to a gate, wherein a rotating shaft of the motor is connected with an input end of the speed reducer, an output end of the speed reducer is connected with an output shaft, a small spiral bevel gear is arranged on the output shaft; the small spiral bevel gear is engaged with a large spiral bevel gear which is sleeved on the screw in the form of a spiral pair. By adopting the spiral bevel gears, the screw type open-close machine has high transmission efficiency, low friction coefficient and long service life.

Description

A kind of worm-type open-close machine
Technical field
The utility model relates to the technical field of headstock gear, the especially a kind of gate opening of large stroke or worm-type open-close machine of closing of being specially adapted to.
Background technology
Existing screw open-close machine as shown in Figure 1, adopt motor 1 to drive large small belt pulley, worm screw 5, worm gear 6 and nut rotation, screw rod 4 is moved up and down, motor 1 positive and negative rotation is nut positive and negative rotation, make screw rod 4 drive gate 3 to move up and down, reach the object that gate 3 is opened or closed.
The above-mentioned screw open-close machine using at present has following shortcoming:
One, worm gear 6, worm screw 5 transmission efficiencies are low;
Two, because worm gear 6 adopts copper part or ductile iron manufacture, worm screw 5 adopts the modified Vehicle Processing manufacture of 45# steel, therefore the accuracy of manufacture is low, roughness is large, and hardness is low, and friction factor is larger, particularly for the unlatching of large stroke (4 meters of >) gate or close, worm gear 6, worm screw 5 are easy to frictional heating, and temperature reaches more than 90 ℃, and the coefficient of expansion is larger;
Three, because worm gear 6, worm screw 5 frictional resistance are large, the flank of tooth of the flank of tooth of worm gear 6 and worm screw 5 is worked and is easily produced friction and leakage of oil under worst hot case, and phenomenon is killed in the flank of tooth generation of the flank of tooth of worm gear 6 and worm screw 5, and application life is low.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem proposing in above-mentioned background technology, the utility model provides a kind of worm-type open-close machine, it adopts the spiral bevel gear of high duty alloy steel making, transmission efficiency is high, friction factor is little, do not generate heat, long service life, is specially adapted to the unlatching of the large stroke of gate or closes.
The utility model solves the technical scheme that its technical problem adopts: a kind of worm-type open-close machine, be used for the unlatching of regulating gate or close, comprise motor, reductor and the screw rod being connected with gate, the rotating shaft of motor is connected with the input of reductor, the output of reductor is connected with output shaft, on output shaft, be provided with small spiral bevel gear, the king bolt bevel gear that small spiral bevel gear is set on screw rod with form with screw pair is meshed.
Further limit: reductor is planet-cycloid reducer.
The beneficial effects of the utility model: this worm-type open-close machine tool has the following advantages:
One, adopt the spiral bevel gear of high duty alloy steel making, through modified quenching grinding technics processing, its accuracy of manufacture is high, and roughness is little, and hardness is high, and supporting capacity is large, and output torque is large, stable working, and strong shock resistance, noise is low;
Two, transmission efficiency is high, can reach 0.92~0.96, is specially adapted to the unlatching of large stroke (4 meters of >) gate or closes;
Three, friction factor is little, does not generate heat, and be original worm gear and the more than 10 times of worm screw the application life of spiral bevel gear, and maintaining is also very convenient.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of existing screw open-close machine;
Fig. 2 is a kind of worm-type open-close machine structural representation of the present utility model.
In figure: 1, motor, 2, reductor, 3, gate, 4, screw rod, 5, worm screw, 6, worm gear, 7, output shaft, 8, small spiral bevel gear, 9, king bolt bevel gear.
The specific embodiment
A kind of worm-type open-close machine as shown in Figure 2, be used for the unlatching of regulating gate 3 or close, comprise motor 1, reductor 2 and the screw rod 4 being connected with gate 3, the rotating shaft of motor 1 is connected with the input of reductor 2, the output of reductor 2 is connected with output shaft 7, on output shaft 7, be provided with small spiral bevel gear 8, the king bolt bevel gear 9 that small spiral bevel gear 8 is set on screw rod 4 with form with screw pair is meshed.Reductor 2 is wherein planet-cycloid reducer.
This worm-type open-close machine adopts motor 1 to drive cycloidal planetary gear speed reducer 2, large small belt pulley, a secondary spiral bevel gear and nut rotation, makes screw rod 4 drive gate 3 to move up and down.Motor 1 positive and negative rotation is nut positive and negative rotation, makes screw rod 4 drive gate 3 to move up and down, and reaches the object that gate 3 is opened or closed.
