Abstract

The invention relates to mechanical engineering, in particular to testing equipment, and can be used in test benches for testing gears according to a closed loop scheme. The purpose of the invention is to expand the technological capabilities by improving the accuracy of determining and setting the load, as well as increasing its durability. The required loading level is set by rotating the flywheel, which with the help of self-braking worm gear ensures the rotation of the supporting disc 10 through the appropriate angle. When the output shafts 5, 6 rotate, the rotation and the block 11 of the gear wheels 12, 13 are received, which, rolling on the gear rims of the wheels 7, B relatively 5, unfold the output rigidly connected with them, the shaft 3, 6 and thereby provide loading of the attached elements stand The load value is recorded by the indicator. Removing the load is achieved by turning the bearing disk 10 in the opposite direction to the zero position of the indicator. 3 il. 15 73- / SSlK 6 SHUI G

Description

The invention relates to mechanical engineering,, 3 specifically to testing equipment, and can be used in test stands for testing 1 and gears in a closed loop circuit.

The purpose of the invention is the expansion of technological capabilities due to the accuracy of determining and setting the load created, as well as its durability.

FIG. depicts a loader, common,; figure 2 - section aa on. on fig.Z - section bb in fig.

The truck contains a base 1 mounted on it with the possibility of rotation of 5 supports 2 3 into the crushing body 4 In the latter, coaxial output shafts are placed with the possibility of turning, for example, high-speed 5 and low-speed 65 connected to the contour branches “On the high-speed shaft 5 installed a cylindrical gear wheel with internal teeth; on a low-speed b, a cylindrical gear wheel 8 with external teeth. A support 9 is fixed in the housing 4, in which the supporting disk 10 with the eccentric shaft axis 5., 6 is placed with an optional rotation, the brush (not marked), the latter is installed with the possibility of rotation of the block 1 of the gears 12, IS, respectively with gears 7, 8 two gears with internal gearing

The self-braking screw of the worm is placed inside the housing 4, while its worm gear 14 is connected to the supporting disk 10, and the supports (not shown) of the screw 15 are connected to the housing 4. At one end of the screw 15 is fixed the flywheel 16. The recording device is a LU lever connected to the body 4 by one end and connected to the other end of the last elastic bar 18 attached to the base 1, and the indicator 9 interacting with the beam 18.

The loader works as follows,.

tarirots. Tse. The rotation angle of the supporting disk 10 and the magnitude of the reactive moment (load created) 5 acting on the body 4 on the loading unit, which is determined by the indicator 19, is experimentally determined. When installing in the stand of the operator, the required loading level is set by rotating the flywheel 16, which with the help of a worm gear, it rotates the platter 10 at an appropriate angle. With the rotation of the output shafts 5.6, the rotation and the block 11 of the gear wheels 12, 3 are received, which, rolling back along the gear rims of the wheels 7, 8 relative to, unfold the rigidly connected wheels. They encoded shafts 5, 6. Mutual rotation of the afterbirth; ShH causes elastic twisting and loading of the associated elements of the stand. The load value is determined by the deformation of the elastic beam 8 and is recorded by indicator 9.

To relieve the load with an axle 18, the support 10 is turned in the opposite direction as long as the reactive moment according to the indications of indicator 19 is not equal to the boom. The coaxial arrangement of the output shafts 5f 6 eliminates the influence of the weight of the attached elements of the stand on their rotation the reactive moment of case 4, and the placement in the last self-brake of the worm gear, noBbmiae.T. durability and safety to work while reducing the labor intensity of the load change.
