[0015] Compared with the prior art, the utility model of a metallurgical special reducer has the following beneficial effects:
[0016] 1. By making the input gear shaft drive the first intermediate shaft to rotate, making the first intermediate shaft drive the worm shaft to rotate, making the worm shaft drive the second intermediate shaft to rotate, and making the second intermediate shaft drive the output shaft, the input speed of the driving device is reduced by four levels to improve the stability of product operation, thereby avoiding the damage of the transmission external teeth due to excessive impact between the transmission external teeth, thereby improving the quality of the product, reducing the operating noise of the product, and improving the user experience of the product. At the same time, by making the worm gear shaft and the worm wheel mesh, not only can the transmission power be turned, but also the self-locking characteristics of the worm gear shaft and the worm wheel can be utilized to avoid the output shaft driving the input gear shaft to rotate in the opposite direction, thereby achieving the role of safety protection of the driving device.
[0017] 2. By setting the input connection keyway on the outside of one end of the input gear shaft, and making the input connection keyway located on the outside of the box, the driving device can be connected to the gear shaft through the input connection keyway, thereby improving the user experience of the product; by setting the connection groove at the end of one end of the output shaft, setting at least two connection holes at the end of one end of the output shaft, and making at least two connection holes communicate with the connection groove, the rotating shaft of the load device can be embedded in the connection groove and connected to the output shaft through multiple connection holes, thereby improving the firmness of the connection between the rotating shaft of the load device and the output shaft, thereby improving the user experience of the product.
[0018] 3. When the highest point of the fourth gear end face contacts the piston rod, the piston rod presses the first spring, so that the first spring is in a compressed state; then, the fourth gear continues to rotate, the first spring resets, and the first spring drives the piston rod to move in the direction of the fourth gear until the piston rod contacts the lowest point of the fourth gear end face; then, the fourth gear continues to rotate, and the fourth gear presses the piston rod to move in the direction of the cylinder body; this reciprocating process causes the piston rod to move back and forth in the buffer chamber. Since the oil suction chamber, the first guide chamber, the buffer chamber and the second guide chamber are connected together, when the piston rod moves in the buffer chamber in the direction of the fourth gear, a negative pressure is formed in the buffer chamber, so that the lubricating oil of the box body enters the buffer chamber through the oil suction chamber and the first guide chamber; when the piston rod moves in the buffer chamber in the direction of the fourth gear, the piston rod pushes out the lubricating oil flowing into the buffer chamber, flows out through the second guide chamber to the return pipe, and flows back into the box body, thereby realizing the reuse of the lubricating oil in the box body.
[0019] 4. When the buffer rod moves toward the direction of the fourth gear, negative pressure is formed in the buffer chamber, and the lubricating oil in the box body flows into the oil suction chamber, so that the lubricating oil pushes the first steel ball to move, so that the first steel ball is separated from the first oil inlet, and then the lubricating oil flows into the first spring seat and flows into the buffer chamber through the first oil outlet; when the buffer rod moves toward the cylinder body, the buffer rod presses the lubricating oil to move toward the second guide chamber, and the lubricating oil will press the first steel ball to move toward the first oil inlet, so that the first steel ball closes the first oil inlet, thereby preventing the lubricating oil from flowing back into the oil suction chamber.
[0020] 5. When the piston rod moves toward the cylinder body and presses the lubricating oil, the lubricating oil pushes the second steel ball to move toward the second spring seat, so that the second steel ball is detached from one end of the second guide chamber, and then the lubricating oil flows into the second guide chamber, flows into the second spring seat through the second oil inlet, and flows into the return oil pipe through the second oil outlet; when the piston rod moves toward the fourth gear and forms a negative pressure in the buffer chamber, the second steel ball is blocked in the second guide chamber, and therefore the lubricating oil in the second guide chamber cannot flow into the buffer chamber.
[0021] 6. By setting the mounting hole on the end face of one end of the piston rod, embedding the third steel ball into the mounting hole, and making the third steel ball fit with the end face of the fourth gear, when the piston rod contacts the fourth gear through the third steel ball, the third steel ball rolls in the mounting hole, thereby preventing the piston rod from scratching the end face of the fourth gear, thereby improving the quality of the product.
[0022] 7. By setting at least two first shock-absorbing holes in the worm gear, the overall mass of the worm gear is reduced, thereby reducing the difficulty of moving the worm gear, thereby improving the user experience of the product. By setting at least two second shock-absorbing holes in the fourth gear, the overall mass of the fourth gear is reduced, thereby reducing the difficulty of moving the fourth gear, thereby improving the user experience of the product.
[0023] 8. By setting the observation port on the top of the box, buckling the observation cover at the observation port, connecting the observation cover to the box, and setting the observation cover to be transparent, the operation inside the box can be observed through the observation cover, so that the parts inside the box can be replaced in time to improve the product usage experience. By installing the vent hood on the observation cover and connecting the vent hood to the inside of the box, the air pressure inside and outside the box can be balanced through the vent hood, thereby improving the product usage experience.

[0041] With the above structure, when the highest point of the end face of the fourth gear 22 contacts the piston rod 28, the piston rod 28 presses the first spring 29, so that the first spring 29 is in a compressed state; then, the fourth gear 22 continues to rotate, the first spring 29 is reset, and the first spring 29 drives the piston rod 28 to move toward the fourth gear 22 until the piston rod 28 contacts the lowest point of the end face of the fourth gear 22; then, the fourth gear 22 continues to rotate, and the fourth gear 22 presses the piston rod 28 to move toward the cylinder body 26; this reciprocating process causes the piston rod 28 to reciprocate in the buffer chamber 27. Since the oil suction chamber 50, the first guide chamber 30, the buffer chamber 27 and the second guide chamber 31 are connected together, when the piston rod 28 moves in the buffer chamber 27 toward the fourth gear 22, a negative pressure is formed in the buffer chamber 27, so that the lubricating oil of the housing 10 enters the buffer chamber 27 through the oil suction chamber 50 and the first guide chamber 30; when the piston rod 28 moves in the buffer chamber 27 toward the fourth gear 22, the piston rod 28 pushes out the lubricating oil flowing into the buffer chamber 27, flows out to the reflux pipe through the second guide chamber 31, and flows back to the housing 10, thereby realizing the reuse of the lubricating oil in the housing 10.
