Incongruous transmission lifter

Abstract

The invention relates to an incongruous transmission lifter, which comprises a box body, an input flange and a double-sided rack. The input flange is fixedly arranged on the box body, an input shaft is arranged on the input flange and an input gear is positioned at the inner end of the input shaft. The box body is rotationally provided with a gear shaft I, a gear shaft II and a gear shaft III, wherein the gear shaft I is fixedly linked with a gear I engaged with the input gear of the input shaft, the gear shaft II is fixedly linked with a gear II, and the gear shaft III is fixedly linked witha gear III. The gear shaft I and the gear shaft III are arranged at two sides of the gear shaft II, and the two ends of the gear II on the gear shaft II are respectively matched with the gear shaft Iand the gear shaft III in a meshed linkage way. The double-sided rack consists of a rack I and a rack II, which are integrated by opposite butt joint. The double-sided rack is arranged between the gear shaft II and the gear shaft III, and the rack I and the rack II thereof are respectively matched with the gear shaft II and the gear shaft III at two sides thereof in a meshed linkage way. The incongruous transmission lifter has the advantages of stable performance, reliable operation and small noise and the like.

Description

technical field [0001] The invention relates to a mechanical transmission device, in particular to a different-direction transmission lifter. Background technique [0002] Traditional hydraulic and pneumatic molding machines are equipped with hydraulic or pneumatic lifters to complete operations such as mechanical clamping and hollow molding, but the existing hydraulic or pneumatic lifters have complex structures and are expensive, and the hydraulic or pneumatic lifters are used for a long time After that, liquid or air leakage often occurs, resulting in slower lifting transmission speed, requiring regular maintenance and replenishment of liquid and air, resulting in high maintenance costs. In addition, on equipment that requires high-precision CNC transmission and lifting, hydraulic and pneumatic lifters cannot achieve sufficient control accuracy and have poor operability.

Problems solved by technology

[0002] Traditional hydraulic and pneumatic molding machines are equipped with hydraulic or pneumatic lifters to complete operations such as mechanical clamping and hollow molding, but the existing hydraulic or pneumatic lifters have complex structures and are expensive, and the hydraulic or pneumatic lifters are used for a long time After that, there will often be liquid or air leakage, resulting in slower lifting transmission speed, requiring regular maintenance and replenishment of liquid and air, resulting in high maintenance costs

In addition, on equipment that requires high-precision numerical control transmission and lifting, hydraulic and pneumatic lifters cannot achieve sufficient control accuracy and have poor operability

[0003] In addition, there is also an existing lifter that performs lifting transmission through a single-sided rack and pinion shaft. Its operating positioning is poor, and the rack is easily displaced, resulting in failures, poor operating stability, and short life.
