Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are done further to describe:
Shown in the accompanying drawing, truck-mounted crane rotary reducer testing table mainly is made up of base 1, bearing support assembly, propulsion system, slippage wheelwork.The bearing support assembly comprises the base 1 that is welded by shaped steel and steel plate; Be fixed with by examination reductor support 2 and supporting upright post 18 by the certain spacing requirement on the base 1; By examination reductor support 2 for by three go up, frame that side, lower steel plate are welded; Its underpart steel plate is welded on the base 1; Be processed with on the top steel plate of examination reductor support 2 and be used to install seam and through hole, and be that the center is uniformly distributed with and is processed with the threaded hole that is used for fixing by the examination reductor with this through hole axis by the examination reductor; Column 18 is the column construction of multistage different-diameter, and on support 1, its top is the less relatively right cylinder of diameter through screw retention in its underpart; Central shaft is to being processed with a tapped blind hole on the top of column 18, and is provided with through the fixing cover plate 12 of set collar 11, is welded with the lug with a through hole on the great circle cylinder of column 18.Supporting upright post 18 is provided with slippage wheelwork and the propulsion system that link to each other with the slippage wheelwork; Said slippage wheelwork mainly is made up of slideway 7, erecting frame 9, screw rod 17, reversing frame 10, revolving sleeve 13, and slideway 7, erecting frame 9 and reversing frame 10 link together through screw retention each other; Reversing frame 10, revolving sleeve 13 is fixed with each other through welding manner; Revolving sleeve 13 is sleeved on supporting upright post 18 tops, its right lower quadrant be welded with a band through hole with supporting upright post 18 on the lug of lug relative position, through lock ring 16 that revolving sleeve 13 is fixing with supporting upright post 18.Revolving sleeve 13 connects erecting frame 9 through reversing frame 10; Slideway 7 is installed on the erecting frame 9; Slideway 7 right sides are provided with the screw rod 17 that is set with threaded sleeve 14 and set nut 15, and the outside of screw rod 17 is provided with crank 8, and said propulsion system mainly are made up of motor 4, shaft coupling 3, sliding seat 5.The top of shaft coupling 3 is processed with the blind hole of band keyway along the axis, its underpart is a male splined shaft, matches with the output shaft of motor 4 with by the splined hole of examination reductor respectively; On sliding seat 5, sliding seat 5 slides on the slideway 7 motor 4, and is fixed together through welding manner and support plate 6 through screw retention; Be processed with a through hole on the support plate 6, be sleeved on the threaded sleeve 14, and both are fixed together, the shaft coupling 3 that the output shaft of motor 4 is provided with and is connected by the examination reductor with set nut 15.
The course of work: extract lock ring 16 before the test earlier, unscrew set collar 11, motor is rotated avoid being tried the installation site of reductor, and tighten set collar 11; To be fixed on by on the examination reductor support 2 by the examination rotary reducer then, and the splined shaft of shaft coupling 3 will be inserted by in the splined hole of examination rotary reducer.
Rotate counterclockwise 17 rotations of crank 8 drive screws, through screw pair threaded sleeve 14 is moved upward, and motor 4 is moved upward along slideway 7, till the upper surface height of motor 4 output axle head height greater than shaft coupling 3 through support plate 6, sliding seat 5.Then, unscrew set collar 11, artificial rotary electric machine 4 rotates in surface level around column 18, till the upper hole of motor 4 output shafts and shaft coupling 3 aligns.At this moment, clockwise rocking-turn crank 8 drive screws 17 rotations move downward threaded sleeve 14 through screw pair, and through support plate 6, sliding seat 5 motor 4 are moved downward along slideway 7 again, till motor 4 output shafts and shaft coupling 3 are worked good fully.At last set collar 11 is tightened, lock ring 16 is inserted in the two lug holes.
When making an experiment, starter motor 4 drives by the rotation of examination rotary reducer through shaft coupling 3, both can carry out break-in to a certain degree to the rotary reducer that newly dispatches from the factory, and can check its assembly quality situation (as going slick property, noise size etc.) again.
Owing to cooperate employing that the screw pair of auto-lock function is arranged between screw rod 17 and the threaded sleeve 14, can guarantee effectively that motor can be under the self gravitation effect and move down.
