2) when the horizontal plane is installed, the lower fixing seats (14) at the bottom of the shell (1) are erected on the support (5), so that the two lower fixing seats (14) are distributed outside the positioning blocks (52), then the second screw (7) penetrates through the lower fixing seats (14) and the positioning blocks (52) and is fixed tightly, and finally the support (5) is fixed on the horizontal installation surface through bolts;

step two, installing a driving shaft: fixing a main driving shaft and an input shaft (21) by using a coupler, then rotating an output shaft (202) to the direction of an auxiliary driving shaft, fixing the output shaft (202) and the auxiliary driving shaft by using the coupler, finally pulling out a positioning gear sleeve (33) of a rotary drum fixing mechanism (3), rotating the positioning gear sleeve (33) to drive a sectional bolt (32) to rotate until the sectional bolt is screwed down, pressing the end part of the sectional bolt on a non-slip mat (206) on the surface of a corresponding rotary drum (205), and fixing the rotary drum (205) and the output shaft (202) therein tightly, wherein the rotary drum can normally work at the moment;

step three, gap adjustment: after the double-face gear (22) and the curved-face gear (203) are in clearance increase after working for a period of time, the rotating sleeve (41) is screwed down, the rotating sleeve pushes the input shaft (21) to move by utilizing the steel balls (43), the double-face gear (22) is close to the curved-face gear (203), and the gear clearance is adjusted;

step four, gap adjustment and detection: in the process of adjusting the clearance, a driving mechanism is started, a main driving shaft drives an input shaft (21) and a double-sided gear (22) on the input shaft to rotate, and further drives a curved-surface gear (203) to rotate, an output shaft (202) drives an output auxiliary driving shaft to rotate, at the moment, a sound collecting device is used for collecting transmission noise, then data are transmitted to an oscilloscope, the tightness of a rotating sleeve (41) is adjusted by observing the waveform on the oscilloscope until the waveform fluctuation reaches the minimum degree, and at the moment, the clearance adjustment is finished.

10. The adjustment test method of the hypoid adjustable gap gear reducer according to claim 9, characterized in that: in the first step, when the speed reducer is installed, one group of the first transmission mechanism (23) and the second transmission mechanism (24) is selected according to the required output ratio, the first transmission mechanism and the second transmission mechanism are adjusted to one side of the output shaft and then installed, and then the angle is finely adjusted.
