The gear box is simple in structure, convenient to manufacture and long in service life.
Description
Technical field
The present invention relates to a kind of transmission device, especially a kind of gear-box, specifically a kind of compact structure, the dynamic balancing machine gear-box that transmission efficiency is high.
Background technique
At present, the common conventional two grades of speed change gears of dynamic balancing machine special gear box, it is little to there is speed ratio mobility scale in this drive mechanism, and bearing capacity is difficult to the series of problems such as raising.And improving constantly of speed and bearing capacity being required along with dynamic balancing machine, be badly in need of that a kind of speed of design is fast, speed ratio change is many, the high Novel speed reducer that simultaneously can control effectively to improve working environment to noise of bearing capacity for.
Summary of the invention
Object of the present invention is few for existing dynamic balancing machine gear, the problem of high speed and heavy duty requirement can not be met, design a kind of dynamic balancing machine gear-box being applicable at a high speed and using under fully loaded transportation condition, and when ensureing normally to use, adopt many grades of speed change gears, reduce cost of production; Increase utilization efficiency; Reduce floor space, be convenient to install, easy to operate.Structure generation process after improvement is more simple, and the manufacture cycle shortens, and improves the market competitiveness.
Technological scheme of the present invention is:
A kind of dynamic balancing machine gear-box, comprise casing 13, input shaft 1 and output shaft 6, the input end of input shaft 1 stretches out outside casing 13 and is connected with drive motor, one end of output shaft 6 is stretched out casing 13 and is connected with testing of electric motors, it is characterized in that one end that described input shaft 1 is arranged in casing 13 is provided with the first gear 2 and the second gear 5, first gear 2 and the second gear 5 engage with the 3rd gear 7 phase on output shaft and the second shaftgear 14 respectively under the effect of the first spline 4 with the second spline 3, described output shaft 6 is provided with the 4th gear 8, 4th gear 8 realizes engaging with the first shaftgear 15 on input shaft 1 or being separated under the effect of the 3rd spline 9 with the 4th spline 10, the first described spline 4 is connected with the first gearshift 12 with the second spline 3, and the 3rd described spline 9 is connected with the second gearshift mechanism 11 with the 4th spline 10.
The 3rd gear 7 on described output shaft 6 and the 4th gear 8 are helical gear.
Beneficial effect of the present invention:
Two grades of gears are improved four-speed gear shift transmission by the present invention first, have both met the test run requirement of dynamic balance running, and have had stable drive again, the advantage that noise is little.
Structure of the present invention is simple, and easily manufactured, the life-span is long.
The present invention can improve speed reducer reliability, reduces cost of production, alleviates workman's working strength, increase productivity, and meets the requirement that national energy-saving reduces discharging.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1.
A kind of dynamic balancing machine gear-box, comprise casing 13, input shaft 1 and output shaft 6, the input end of input shaft 1 stretches out outside casing 13 and is connected with drive motor, one end of output shaft 6 is stretched out casing 13 and is connected with testing of electric motors, one end that described input shaft 1 is arranged in casing 13 is provided with the first gear 2 and the second gear 5, first gear 2 and the second gear 5 can adopt helical gear with the 3rd gear 7(on output shaft respectively under the effect of the first spline 4 with the second spline 3) mutually and the second shaftgear 14 engage, described output shaft 6 is provided with the 4th gear 8(and can adopts helical gear), 4th gear 8 realizes engaging with the first shaftgear 15 on input shaft 1 or being separated under the effect of the 3rd spline 9 with the 4th spline 10, the first described spline 4 is connected with the first gearshift 12 with the second spline 3, and the 3rd described spline 9 is connected with the second gearshift mechanism 11 with the 4th spline 10, as shown in Figure 1.The present invention may be combined with into four speed ratios, and they are respectively:
First speed ratio: when spline 4 engages with spline 3 and gear 2, spline 9 engages with spline 10;
Second speed ratio: when spline 4 engages with spline 3 and gear 5, spline 9 engages with spline 10;
3rd speed ratio: when spline 4 engages with spline 3, spline 9 engages with spline 10 and gear 8;
4th speed ratio: when spline 4 engages with spline 3, spline 9 engages with spline 10.
The helical gear material of all parallel axes in the present embodiment should more than MQ level (as 17CrNiMo6 high-quality steel), and key area flaw detection requirement should more than three grades, carburizing and quenching before gear grinding Shot peening.Gear-box preferably adopts three-dimensional software solidworks and GO2 to carry out structural design to meet rigidity requirement.
Drive path of the present invention is: gear-box is by driven by motor input shaft 1, input shaft 1 is put by group gear and is realized four-speed gear shift: driven by motor input shaft gear combines, output shaft gear combination is driven by gear shifting structure, four kinds of speed ratios can be obtained like this and these four kinds of speed ratios are transferred to from output shaft 6 dynamic balance running that testing machine realizes friction speed, so that more fully simulated machine runs various operating modes.
First gearshift 12, second gearshift mechanism 11 of the present invention can adopt gearshift mechanism conventional in the gear-box of prior art to be realized.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
