[0039] Embodiment 3

[0040] As attached Figure 1As shown, the hydraulic cylinder 3 of the present invention is connected to the hydraulic system, which includes a hydraulic station 31, an accumulator 32 installed on one side of the hydraulic station 31, a motor pump group 33 and a control valve group 34 installed at intervals on the top surface of the hydraulic station 31, and a high and low pressure switch 35. The oil pipe 36 of the hydraulic station is connected to the oil port of the hydraulic cylinder 3; the accumulator 32 is installed on one side of the hydraulic station 31 through a clamp, and the working oil pipe of the accumulator 32 is connected to the corresponding oil port of the control valve group 34; the control valve group seat is installed on the hydraulic station, and a control valve and a high and low pressure switch are installed on it. Interface A and interface B are set on the side of the control valve group 34, and interface A and interface B are respectively connected to port a and port b of the hydraulic cylinder 3; the motor pump group 33 is vertically installed on the hydraulic station, and its hydraulic pump is installed below the motor by means of a flange and immersed in the hydraulic oil in the hydraulic station.

[0041] As attached Figure 1-8 As shown, the overall working process of the present invention is as follows: the output shaft of the hydraulic motor 16 drives the cogwheel 2 to rotate through the rotary reducer 20, and the cogwheel 2 moves the pin teeth 5 to rotate the bottom of the annular furnace. During the period of meshing transmission between the cogwheel 2 and the pin teeth 5, the slide plate 11 always keeps a sliding state, so that the outer wall of the annular compensation pressure plate 7 and the outer circle of the pin tooth seat 4 are closely attached, thereby ensuring the correct meshing size.

[0042] If the pin tooth pitch circle diameter error is positive at the moment of meshing, the outer dome of the pin tooth seat 4 will press against the outer wall of the annular compensation pressure plate 7, pushing the hydraulic motor 16 so that the motor mounting seat 14 drives the slide plate 11 to slide to the right, and the oil rod of the hydraulic cylinder 3 will retreat to the right, so that the cogwheel 2 will mesh with the pin tooth 5, and the hydraulic oil in the rodless chamber will be filled into the accumulator, but the positive pressure will always be maintained to ensure the close fit between the outer wall of the annular compensation pressure plate 7 and the pin tooth seat 4.

[0043] If the pin gear pitch circle diameter error is negative at the moment of engagement, the oil rod of the hydraulic cylinder 3 extends to the left and drives the slide plate 11 to slide to the left through the link seat 6, and the slide plate 11 drives the motor mounting seat 14 and the hydraulic motor 16 to move to the left. The outer wall of the annular compensation pressure plate 7 presses against the outer circle of the pin gear seat 4, so that the cogwheel 2 and the pin gear 5 engage. At this time, the hydraulic oil of the rodless cylinder is charged through the accumulator, but the positive pressure is always maintained to ensure the close fit between the pin gear seat and the compensation pressure plate.

[0044] During the rotation of the annular furnace at the bottom, the oil rod of the hydraulic cylinder is extended and retracted, and is automatically adjusted to keep the cogwheel 2 and the pin tooth 5 in meshing.

[0045] When the hydraulic system is working, if the pressure in the accumulator 32 is lower than the pressure set by the low-pressure switch, the motor pump group starts to charge the accumulator 32. If the pressure reaches the pressure set by the high-pressure switch, the motor pump group 33 is powered off and stops running. This action is repeated. In one cycle, the motor pump group 33 is in a power-off state for a long time, and the energy-saving effect is obvious.

[0046] The present invention installs an annular compensation pressure plate on the top of the cogwheel 27, and the oil rod of the hydraulic cylinder 3 is extended and retracted, and the slide plate 11 is driven to slide through the link seat 6, and the slide plate 11 drives the motor mounting seat 14 and the hydraulic motor 16 to move, so as to automatically compensate for the error gap when the pin tooth 5 and the cogwheel 2 are meshed, and eliminate the problems of frustration, poor precision and discontinuity of the furnace bottom rotation caused by the non-tangency of the cogwheel pitch circle and the pin tooth pitch circle during meshing caused by processing and assembly errors at every moment when the annular furnace bottom rotates, so that the annular compensation pressure plate 7 and the pin tooth seat 4 are in contact and automatically adjusted so that the cogwheel 2 and the pin tooth 5 are always kept in meshing, thereby providing a guarantee for the continuous and reliable operation of the thermal production line.
