Description

A kind of column reducing gear
Technical field
The utility model relates to the column reducing gear that a kind of electric elevatable table or raising platform use.
Background technique
Existing electric elevatable table is generally 90 ° of outputs for the reducing gear of column up-down, and namely the output shaft of reducing gear 01 and column agency 02 are in 90 ° of angles, and coordinated by worm gear structure or angular wheel structure driven therebetween, structure as shown in Figure 1.Owing to adopting 90 ° of outputs, this structure deposits that volume is after mounting comparatively large, take up room the problem large, column stroke is little.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of column reducing gear, can reduce the installation volume of column agency and reducing gear, increases column stroke.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of column reducing gear, comprise speed reducer, in speed reducer, worm screw is installed, worm gear, first helical gear, second helical gear and the 3rd helical gear, worm and wheel engages, the rotary centerline of worm gear is perpendicular to the rotary centerline of worm screw, first helical gear is coaxial with worm gear and the two relative circumference is fixing, first helical gear and the engagement of the second helical gear, second helical gear and the engagement of the 3rd helical gear, second helical gear rotary centerline and the 3rd helical gear rotary centerline are all parallel to the rotary centerline of worm screw, 3rd helical gear has the installation position for installing column.
As preferably, first helical gear is two, two the first helical gears lay respectively at the both sides of worm gear, accordingly, second helical gear is also two, one of them second helical gear engages with first helical gear, another second helical gear engages with another first helical gear, and two the second helical gears all engage with the 3rd helical gear.Adopt two the first helical gears and two the second helical gears and the 3rd Helical gear Transmission cooperating structure.Driven by motor worm gear wheel, worm gear and two the first gears rotate simultaneously, two the first gears drive two the second pinion rotation simultaneously, two the second gears drive the 3rd pinion rotation simultaneously, driving torque or torsion are shared by two the first helical gears and two the second helical gears simultaneously, compared with a gear, under load condition, can not gear failure be caused, improve stability and the working life of the 3rd helical gear transmission.
As preferably, worm screw is trapped among worm gear, between two the first helical gears and two the second helical gears.Compact structure, reduces whole organization volume further.
Beneficial effect:
A kind of column reducing gear that the utility model adopts technique scheme to provide, the reduced column agency of reducing gear and the installation volume of reducing gear, making between column agency and reducing gear is minimum mounting distance, and then increases column stroke.

Fig. 1 is the structural representation that existing reducing gear coordinates with column agency;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is plan view of the present utility model;
Fig. 4 is sectional view of the present utility model.
Embodiment
As shown in Figures 2 to 4, a kind of column reducing gear, comprise speed reducer 2, worm screw 11 is installed in speed reducer 2, worm gear 3, first helical gear 4, second helical gear 5 and the 3rd helical gear 6, speed reducer 2 is provided with motor 1, worm screw 11 is directly the output shaft (worm screw 11 also can be fixedly connected with the output shaft of motor 1) of motor 1, worm screw 11 engages with worm gear 3, the rotary centerline of worm gear 3 is perpendicular to the rotary centerline of worm screw 11, first helical gear 4 is coaxial with worm gear 3 and the two relative circumference is fixing, first helical gear 4 and the second helical gear 5 engage, the rotary centerline of the second helical gear 5 is parallel to the rotary centerline of worm screw 11, second helical gear 5 and the 3rd helical gear 6 engage, the rotary centerline of the 3rd helical gear 6 is parallel to the rotary centerline of worm screw 11, 3rd helical gear 6 has the installation position 61 for installing column.In the present embodiment, first helical gear 4 is two, two the first helical gears 4 lay respectively at the both sides of worm gear 3, accordingly, second helical gear 5 is also two, two the second helical gears 5 are positioned at two second helical gear the same sides, one of them second helical gear 5 side is engaged with first helical gear 4, opposite side engages with the 3rd helical gear 6, another the second helical gear 5 side is engaged with another first helical gear 4, opposite side engages with the 3rd helical gear 6, two the first helical gears and two the second helical gears are adopted to coordinate drive the 3rd helical gear to rotate with the 3rd Helical gear Transmission, improve the stability of the 3rd helical gear transmission, reduce the first helical gear, second helical gear and the 3rd helical gear rigid requirements, improve the working life of column reducing gear.In the present embodiment, worm screw 11 is trapped among between worm gear 3, two the first helical gears 4 and two the second helical gears 5, and structure can be made more compact.
Working procedure is: machine operation drives worm screw 11 rotate and then drive worm gear 3 to rotate, worm gear 3 rotates drive two the first helical gear 4 synchronous axial system, two the first helical gears 4 rotate and drive two the second helical gears 5 to rotate respectively, second helical gear 5 rotates, and drive the 3rd helical gear 6 to rotate, the 3rd helical gear 6 rotates and then drives column agency work.
