A linear driving device comprises a gearing, a hollow casing tube, a worm screw, a hollow positioning ring and a hollow positioning rod. The utility model is characterized in that one end of the gearing is provided with a hollow gear box and a sheathing part, the outer diameter of one end of the hollow casing tube is smaller than that of the sheathing part and just penetrated in the sheathing part, the other end of the hollow casing tube is exposed out of the sheathing part, and the inner wall of the hollow casing tube is provided with an embedded slot. The worm screw is provided with a bearing, and an outer sleeve of the bearing and a gear ring engaged with the worm screw are arranged in the hollow gear box. The utility model is used for transmission.
Description
The utility model relates to transmission device.
Existing linear actuator comprises driver, linear axes, axle sleeve, gear-box and train of reduction gears, output speed is passed on the linear axes the protruding or axle sleeve of inwardly withdrawing of this linear axes through it, this volume is big by complicated gear transmission group transmission, construction inconvenience, fault is many, complex structure.
The purpose of this utility model provides that a kind of volume is less, the better simply linear actuator of structure.
The purpose of this utility model is achieved in that linear actuator, and it comprises: a transmission device, hollow sleeve, worm screw, hollow positioning ring and a hollow positioning rod is characterized in that: this transmission device one end is established a hollow gear case, and is provided with a belled part; Hollow sleeve one end external diameter just is set in the belled part less than the belled part external diameter, and end exposes outside the belled part in addition, and the hollow sleeve inwall has caulking groove; Worm screw has a bearing, and the gear ring of bearing outside and worm meshing also places in the hollow gear case, and the worm screw periphery is provided with the screw section; Hollow positioning ring one end external diameter is slightly larger than in addition end, and the big end of external diameter is provided with and the sleeve pipe caulking groove inlay of buckle mutually, and other holds periphery to be provided with an external thread part, and the positioning ring inner edge is provided with internal thread part, and this internal thread part is sheathed between worm screw and the sleeve pipe; The hollow positioning rod is between worm screw and sleeve pipe, and positioning rod one end inner edge is provided with another screw section, the mutual interlocking of external thread part of this another screw section and positioning ring, and the positioning rod ora terminalis is against the ora terminalis place of the bigger end of positioning ring external diameter.
Above-mentioned design makes the direct driving gear torus of screw rod, makes screw rod rotation, and then makes the different to-and-fro motion of doing forward or backward of sense of rotation with worm screw of positioning ring and positioning rod, thereby reaches little, the simple effect of body.
Further specify again below by accompanying drawing, embodiment.
Fig. 1 the utility model three-dimensional exploded view;
Fig. 2 the utility model partial sectional view.
As Fig. 1,2, the utility model comprises: a transmission device 10, hollow sleeve 20, worm screw 30, hollow positioning ring 40 and a hollow positioning rod 50 is characterized in that: these transmission device 10 1 ends are established a hollow gear case 11, and are provided with a belled part 13; Hollow sleeve 20 1 end external diameters just are set in the belled part 13 less than belled part 13 external diameters, and end exposes outside the belled part 13 in addition, and hollow sleeve 20 inwalls have caulking groove 21; Worm screw 30 has a bearing, and bearing outside and worm screw 30 meshed gears rings 31 also place in the hollow gear case 11, and worm screw 30 peripheries are provided with screw section 32; Hollow positioning ring 40 1 end external diameters are slightly larger than end in addition, the big end of external diameter is provided with and sleeve pipe 20 caulking grooves 21 inlay 41 of buckle mutually, other holds periphery to be provided with an external thread part 42, and positioning ring 40 inner edges are provided with internal thread part 43, and this internal thread part 43 is sheathed between worm screw 30 and the sleeve pipe 20; Hollow positioning rod 50 is between worm screw 30 and sleeve pipe 20, and positioning rod 50 1 end inner edges are provided with another screw section, the external thread part 42 mutual interlockings of this another screw section and positioning ring 40, and positioning rod 30 ora terminalis are against the ora terminalis place of the bigger end of positioning ring 40 external diameters.Wherein, be provided with motor in this transmission device 10 as power.Wherein, set belled part 13 inner edges of these gear-box 11 1 ends are provided with packing rib 14, so that an end of sleeve pipe 20 can firmly be sheathed in the belled part 13.Wherein, these gear-box 11 inner edges are provided with a breach 15 corresponding to positioning ring 40 inlays 41, and make positioning ring 40 can pass gear-box 11.
The utility model is a kind of linear actuator 1, containing space 12 in its gear-box 11 can ccontaining one screw rod that is meshed with gear ring 31, and worm screw 30 1 ends are provided with the bearing (not shown), when transmission device 10 rotations, screw rod is transferred on the worm screw 30, worm screw 30 rotations.The internal thread part 43 of positioning ring 40 screws togather with the screw section 32 of worm screw 30, and positioning rod 50 1 end inner edges have the external thread part 42 mutual interlockings of a screw section (not shown) and positioning ring 40 in addition.During use, make screw rod rotate, change with the turn direction of worm screw 30 by positioning ring 40 and cause to-and-fro motion, make positioning rod 50 protruding or inside withdrawals, avoided adopting complicated reduction gear box, gear-box 11 as above is simple structure then, volume is small and exquisite, for use has brought convenience.
