Abstract

The invention relates to the field of mechanical engineering, in particular to testing equipment, and can be used for running-in (grinding in) gears of multi-threaded gearboxes in their own housing. The aim of the invention is the expansion of technological capabilities by providing a preliminary sample of the total circumferential gaps. Depending on the direction of the loading moment, for example clockwise, the protrusion 6 moves in the groove 4 until the crown 2 stops against it. The protrusion 5 moves to the contact with the retainer 10 and is fixed in the groove 3. Then the bolt 8 is screwed in by the total circumferential gap. Further screwing in the bolt 8 creates a load. 2 Il. % k / oe ate to 00 ate N)

Description

FIG. one

The invention relates to mechanical engineering, in particular to testing equipment, can be used when running-in (grinding in) gears of multi-threaded gearboxes in its own case and relates to the improvement of the known device according to ed. St. USSR №1313598.

The aim of the invention is the expansion of technological capabilities by providing a preliminary sample of the total circumferential gaps.

FIG. 1 shows a splined crown placed on a torsion shaft; in fig. 2 shows a section A-A in FIG.

The device contains a torsion shaft 1 mounted in supports (not shown) intended to accommodate one of the intermediate shafts of the test multi-flow reducer, at one end of which a pulley rim (not shown) is rigidly fixed. At the free end of the shaft 1 is installed with the possibility of rotation of the spline crown 2, in which there are two curved grooves 3, 4, which are mirrored relative to the radial plane. In the slots 3, 4, the projections 5, 6 are mounted for movement and fixation with a threaded hole 7, into which adjusting bolts 8, 9 are screwed, which cooperate with a removable clamp 10 fixed to the end of the torsion shaft 1. Fixing the projections 5, 6 in the grooves 3 , 4 is carried out with the help of nuts 11, 12, placed on the threaded end of each projection 5, 6.

The device works as follows.

Depending on the given direction of the loading moment, one of the protrusions, for example 6, moves in the groove 4, clockwise up to the stop in the body of the crown 2. The protrusion 5, in which

The adjustment bolt 8 is inverted, shifted clockwise until it touches latch 10 and secured in groove 3 with nuts 11 and 12. Then bolt 8 is screwed in by an amount equivalent to the total circumferential gap existing in the kinematic chain of the gearbox. The moment of the choice of the gap is determined by the force applied when screwing in the bolt 8. Further screwing of this bolt leads to rotation of the movable spline crown 2 relative to the torsion shaft 1 with the fixed crown and mutual rotation of the gearbox wheels, i.e. tooth loading by the method of closed power flow. After that, the protrusion 6 is brought counterclockwise to the latch 10 and fixed in the groove 4, and the adjusting bolt 9 is screwed in against the stop into the latch 10.

Such an improvement in the design of the device provides an increase in the angles of mutual reversal of the torsion shaft and the movable spline crown and, thereby, an increase in the range of test gears having significant total circumferential gaps, as claimed.
