The dynamic balancing machine gear-box
Technical field
The present invention relates to a kind of transmission device, especially a kind of gear-box, a kind of compact structure specifically, the dynamic balancing machine gear-box that transmission efficiency is high.
Background technique
At present, the common two grades of speed change gears commonly used of dynamic balancing machine special gear box, this drive mechanism exists the speed ratio mobility scale little, and bearing capacity is difficult to a series of problems such as raising.And along with dynamic balancing machine to improving constantly that speed and bearing capacity require, be badly in need of that a kind of speed of design is fast, speed ratio change many, bearing capacity is high can control effectively to improve the novel speed reducer of working environment for use to noise simultaneously.
Summary of the invention
Purpose of the present invention is few at existing dynamic balancing machine gear, can not satisfy the problem that high speed and heavy duty require, design a kind of being applicable at a high speed and the dynamic balancing machine gear-box that uses under the fully loaded transportation condition, and guarantee under the situation about normally using, adopt many grades of speed change gears, reduce production costs; Increase utilization efficiency; Reduce floor space, be convenient to install, easy to operate.Structure production technology after the improvement is simpler, and the manufacture cycle shortens, and has improved 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 the casing 13 and links to each other with drive motor, one end of output shaft 6 stretches out casing 13 and links to each other with testing of electric motors, it is characterized in that described input shaft 1 is arranged on the end of casing 13 is equipped with first gear 2 and second gear 5, first gear 2 and second gear 5 under the effect of first spline 4 and second spline 3 respectively with output shaft on the 3rd gear 7 reach 14 engagements of second shaftgear mutually, be equipped with on the described output shaft 6 the 4th gear 8, the four gears 8 realize under the effect of the 3rd spline 9 and the 4th spline 10 with input shaft 1 on 15 engagements of first shaftgear or separate; Described first spline 4 links to each other with first gearshift 12 with second spline 3, and described the 3rd spline 9 links to each other with second gearshift mechanism 11 with the 4th spline 10.
The 3rd gear 7 and the 4th gear 8 on the described output shaft 6 are helical gear.
Beneficial effect of the present invention:
The present invention improves the four-speed gear shift transmission with two grades of speed change transmissions first, has both satisfied the test run requirement of dynamic balance running, has stable drive again, the advantage that noise is little.
The present invention is simple in structure, and is easily manufactured, and the life-span is long.
The present invention can improve the speed reducer reliability, reduces cost of production, alleviates workman's working strength, increases productivity, and meets the requirement of national energy-saving and emission-reduction.

Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
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 the casing 13 and links to each other with drive motor, one end of output shaft 6 stretches out casing 13 and links to each other with testing of electric motors, described input shaft 1 is arranged on the end of casing 13 first gear 2 and second gear 5 is installed, first gear 2 and second gear 5 under the effect of first spline 4 and second spline 3 respectively with output shaft on the 3rd gear 7(can adopt helical gear) reach 14 engagements of second shaftgear mutually, the 4th gear 8(is installed on the described output shaft 6 can adopts helical gear), the 4th gear 8 realize under the effect of the 3rd spline 9 and the 4th spline 10 with input shaft 1 on 15 engagements of first shaftgear or separate; Described first spline 4 links to each other with first gearshift 12 with second spline 3, and described the 3rd spline 9 links to each other with second gearshift mechanism 11 with the 4th spline 10, as shown in Figure 1.Four speed ratios of the present invention's one-tenth capable of being combined, they are respectively:
First speed ratio: when spline 4 and spline 3 and gear 2 engagements, spline 9 and spline 10 engagements;
Second speed ratio: when spline 4 and spline 3 and gear 5 engagements, spline 9 and spline 10 engagements;
The 3rd speed ratio: when spline 4 and spline 3 engagements, spline 9 and spline 10 and gear 8 engagements;
The 4th speed ratio: when spline 4 and spline 3 engagements, spline 9 and spline 10 engagements.
The helical gear material of all parallel axes in the present embodiment should be more than the MQ level (as 17CrNiMo6 high-quality steel), and key area flaw detection requirement should be more than three grades, carburizing and quenching and Shot peening before the gear grinding.Gear-box preferably adopts three-dimensional software solidworks and GO2 to carry out structural design to satisfy rigidity requirement.
Drive path of the present invention is: gear-box is by driven by motor input shaft 1, input shaft 1 puts to realize four-speed gear shift by dialling gear: the combination of driven by motor input shaft gear, drive the output shaft gear combination by the gearshift structure, can obtain four kinds of speed ratios like this and these four kinds of speed ratios are transferred to the dynamic balance running that testing machine is realized friction speed from output shaft 6, so that more fully simulated machine moves various operating modes.
First gearshift 12 of the present invention, second gearshift mechanism 11 can adopt the gearshift mechanism of using always in the gear-box of prior art to be realized.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
