Description
Technical field
The utility model 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 the 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 the high Novel speed reducer that can control effectively to improve working environment to noise simultaneously of many, bearing capacity for.
Summary of the invention
The purpose of this utility model is few for 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 fully loaded transportation condition, and in the situation that guarantee normally to use, 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 improvement is simpler, and the manufacture cycle shortens, and has improved the market competitiveness.
The technical solution of the utility model 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 stretches out casing 13 and is connected with testing of electric motors, it is characterized in that described input shaft 1 is arranged on an end of casing 13 is equipped with the first gear 2 and the second gear 5, the first gear 2 and the second gear 5 under the effect of the first spline 4 and the second spline 3 respectively with output shaft on the 3rd gear 7 reach mutually the second shaftgear 14 engagements, the 4th gear 8 is installed on described output shaft 6, the 4th gear 8 realize under the effect of the 3rd spline 9 and the 4th spline 10 with input shaft 1 on the first shaftgear 15 engagements or separate, described the first spline 4 is connected with the first gearshift 12 with the second spline 3, and described the 3rd spline 9 is connected with the second gearshift mechanism 11 with the 4th spline 10.
The 3rd gear 7 and the 4th gear 8 on described output shaft 6 are helical gear.
The beneficial effects of the utility model:
The utility model improves the four-speed gear shift transmission with two grades of gears first, has both satisfied the test run requirement of dynamic balance running, has again stable drive, the advantage that noise is little.
The utility model is simple in structure, and is easily manufactured, and the life-span is long.
The utility model can improve the speed reducer reliability, reduces cost of production, alleviates workman's working strength, increases productivity, and meets the requirement that national energy-saving reduces discharging.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
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 stretches out casing 13 and is connected with testing of electric motors, described input shaft 1 is arranged on an end of casing 13 the first gear 2 and the second gear 5 is installed, the first gear 2 and the second gear 5 under the effect of the first spline 4 and the second spline 3 respectively with output shaft on the 3rd gear 7(can adopt helical gear) reach mutually the second shaftgear 14 engagements, the 4th gear 8(is installed on 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 the first shaftgear 15 engagements or separate, described the first spline 4 is connected with the first gearshift 12 with the second spline 3, and described the 3rd spline 9 is connected with the second gearshift mechanism 11 with the 4th spline 10, as shown in Figure 1.Four speed ratios of the utility model 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 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 utility model 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 gear shifting structure, can obtain like this four kinds of speed ratios and these four kinds of speed ratios are transferred to from output shaft 6 dynamic balance running that testing machine is realized friction speed, so that more fully simulated machine moves various operating modes.
