Description
Technical field
The utility model relates to worm and gear technical field, particularly relates to a kind of worm wheel and worm rod pair driving mechanism.
Background technique
The transmission of worm and worm wheel is called worm drive, worm drive is a kind of basic mechanical structure, for motion and the power of transmission two spatial intersecting axles, because of it, to have reduction speed ratio large, compact structure, the advantages such as stable working, are thus widely used in various retarding device and mechanical transmission.But because worm drive carries out transmission by the teeth face friction between worm and wheel, when therefore its intrinsic shortcoming is reciprocal transmission, friction produces higher heat, and cause wearing and tearing, working life is short, and precision is poor.
Model utility content
For solving the technical problem existed in background technique, the utility model proposes a kind of worm wheel and worm rod pair driving mechanism, reasonable in design, easy to process, the heat coordinating and produce in transmission can be reduced, good cooling results.
A kind of worm wheel and worm rod pair driving mechanism that the utility model proposes, comprising: worm gear, worm screw, drive unit, coolant circulation unit;
Worm gear periphery is provided with teeth portion, worm screw face is provided with outside thread, worm gear is coordinated with the outside thread of worm screw by teeth portion, drive unit drives worm screw to rotate, worm screw adopts Heat Conduction Material to make, worm screw inside is provided with the through hole extended vertically, and through hole two ends are respectively equipped with stuffing box bearing, and through-hole wall is provided with the internal thread that arrange corresponding to outside thread;
Coolant circulation unit comprises coolant pump and is connected to liquid inlet pipe and the drain pipe at coolant pump two ends, and liquid inlet pipe and drain pipe are connected to worm screw two ends away from one end of coolant pump respectively by stuffing box bearing.
Preferably, worm screw one end is provided with driving gear, and drive unit comprises the actuation gear coordinated with driving gear.
Preferably, worm screw bar wall arbitrary position thickness is equal.
Preferably, teeth portion adopts heat resistant and wear resistant material to make.
In the utility model, the worm wheel and worm rod pair driving mechanism proposed, worm screw adopts Heat Conduction Material to make, its inside is provided with the through hole extended vertically, through-hole wall is provided with the internal thread that arrange corresponding to worm screw outside thread, through hole two ends are respectively equipped with stuffing box bearing, coolant circulation unit two ends are connected with the rotary seal of through hole two ends with drain pipe respectively by liquid inlet pipe, during work, coolant circulation unit is by through hole that cooling liquid to be sent into by liquid inlet pipe in the middle part of worm screw, along with the rotation of worm screw, cooling liquid flows through in through hole along internal thread, on the one hand, the setting of internal thread increases the surface area of through-hole wall, improve cooling-down effect, on the other hand, cooling liquid flows along internal thread, screw type stream is formed in through hole, extend the time that cooling liquid flows through through hole, further raising cooling-down effect, effective cooling cooling is carried out to the cooperation transmission of worm and gear.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of worm wheel and worm rod pair driving mechanism that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of worm wheel and worm rod pair driving mechanism that the utility model proposes.
With reference to Fig. 1, a kind of worm wheel and worm rod pair driving mechanism that the utility model proposes, comprising: worm gear 1, worm screw 2, drive unit, coolant circulation unit 4;
Worm gear 1 periphery is provided with teeth portion 11, teeth portion 11 adopts heat resistant and wear resistant material to make, worm screw 2 surface is provided with outside thread, worm gear 1 is coordinated with the outside thread of worm screw 2 by teeth portion 11, worm screw 2 adopts Heat Conduction Material to make, worm screw 2 inside is provided with the through hole 21 extended vertically, through hole 21 two ends are respectively equipped with stuffing box bearing, through hole 21 inwall is provided with the internal thread that arrange corresponding to outside thread, worm screw 2 bar wall arbitrary position thickness is equal, worm screw 2 one end is provided with driving gear 22, drive unit comprises the actuation gear 32 that drive portion 31 coordinates with driving gear 22, rotate to drive worm screw 2,
Coolant circulation unit 4 comprises coolant pump 41 and is connected to liquid inlet pipe 42 and the drain pipe 43 at coolant pump 41 two ends, and liquid inlet pipe 42 and drain pipe 43 are connected to worm screw 2 two ends away from one end of coolant pump 41 respectively by stuffing box bearing.
When the worm wheel and worm rod pair driving mechanism of the present embodiment works, the drive portion of drive unit drives its actuation gear to rotate, worm screw is driven to rotate by driving gear, worm gear moves along worm screw along with the rotation of worm screw, the heat produced in worm and gear reciprocal transmission is transmitted in through hole by worm screw wall, simultaneously cooling liquid to be sent in the through hole in the middle part of worm screw by liquid inlet pipe by coolant pump, along with the rotation of worm screw, cooling liquid flows through in through hole along internal thread, screw type stream is formed in through hole, take away the heat penetrated by worm screw wall, then coolant pump is flowed back to from the other end via drain pipe, realize recycling of cooling liquid, on the one hand, the setting of internal thread increases the surface area of through-hole wall, improve cooling-down effect, on the other hand, cooling liquid flows along internal thread, forms screw type stream in through hole, extends the time that cooling liquid flows through through hole, further raising cooling-down effect, carries out effective cooling cooling to the cooperation transmission of worm and gear.
