Description

Technical Field

[0001] The utility model relates to the technical field of speed reducers, in particular to a vertical twin-screw rotary speed reducer. Background Art

[0002] The twin-screw rotary reducer reduces the rotation speed of the motor through the mutual transmission between the two screws to adapt to the rotation of other objects. At the same time, it has good stability and large torque during the speed reduction process, so it is not easy to be damaged.

[0003] However, most of the existing reducers use the spiral groove on the screw to perform meshing deceleration, and this type of deceleration can only achieve single-efficiency deceleration and cannot adjust the deceleration efficiency. Therefore, we propose a vertical twin-screw rotary reducer to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art involved in the background technology and to propose a vertical twin-screw rotary reducer.

[0007] The first transmission shaft can drive the second transmission shaft to rotate through the first transmission gear and the second transmission gear to complete the speed reduction process. At the same time, there are multiple groups of first transmission gears and second transmission gears, and the speed reduction efficiency can be adjusted by different combinations of first transmission gears and second transmission gears.

[0011] A person can directly drive the second transmission gear to move by sliding the sliding slot from the outside, thereby making the movement of the second transmission gear more convenient.

[0012] Preferably, a pulling plate is provided at the end of the connecting rod, the pulling plate is located outside the mounting shell, fixed embedded rods are inserted on both sides of the pulling plate, fixed embedded holes are opened on both sides of the outer wall of the mounting shell, and the fixed embedded rods and fixed embedded holes are adapted to each other;

[0013] The pulling plate can drive the connecting rod to move, and then when it moves to the specified position, the fixed embedded rod can be embedded in the fixed embedded hole for limit fixation, so that the pulling plate can position the connecting rod to prevent the second transmission gear from disengaging.

[0014] Preferably, a support spring is sleeved on the outside of the fixed embedded rod, one end of the support spring is fixedly connected to the fixed embedded rod, and the other end of the support spring is fixedly connected to the end of the pulling plate;

[0017] The connecting plate can support the connecting rod, thereby preventing the connecting rod from tilting or falling off.

[0018] Preferably, a fixed shaft is provided inside the movable slot, and the connecting plate is sleeved on the outside of the fixed shaft;

[0019] The connecting plate can be further positioned to further avoid the connecting rod from tilting.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The utility model can slide the connecting rod so that the connecting rod drives the support bracket to move, so that the second transmission gear can slide, so that the two groups of second transmission gears are disengaged from the corresponding first transmission gears, and the other group of second transmission gears are correspondingly transmitted with the first transmission gear to complete the deceleration processing.

At the same time, the middle position of the connecting rod is positioned by the connecting plate and the fixed shaft rod to prevent the connecting rod from tilting and detaching, thereby improving the supporting effect of the connecting rod.
