SED Rack and Pinion Lift RJ10 Internal Flat Machine Special Screw Lift

SNJ rack and pinion lift is a synchronous lifting mechanism that combines a rack and pinion. It can be directly driven by a motor to perform rotary motion while simultaneously driving the pinion for linear motion.

With almost no power loss, it maximizes machine efficiency. It has a simple structure, low failure rate, and is easy to maintain.

The worm reducer inside the lift achieves speed reduction, resulting in slow lifting speed, making it suitable for precision lifting or heavy load lifting. The SNJ rack and pinion lift is directly connected by gears and racks, enabling high-speed linear motion. It can be precisely controlled using a geared motor with an attached brake.

RJ Series Rack and Pinion Lift

1. It is the basic separable model, with specifications ranging from RJ10 to RJ50. It can be divided into three specifications based on the direction of the output shaft.

2. Driven by a cylinder, it has no internal reduction, allowing for rapid movement.

1. Working principle: Relying on the interaction between the gear and rack, it ensures synchronous lifting of four or more support points, thereby achieving smooth lifting of the work platform. The synchronization error among the four support points can be as small as

2. Structure and performance of the synchronous lift:

① The synchronous lift consists of a gear and rack assembly combined with a gearbox connecting shaft. It is a unit used to maintain synchronization between the upper and lower surfaces during up/down operations.

② Several gears inside the gearbox mesh and operate, resulting in almost no noise.

③ During up/down motion, it can operate normally even under a bias of up to 50%.

④ Its guide rails are modularized components assembled in unit form.

The lift is a passive type, using a cylinder as the power source, with the lift serving a guiding and synchronizing role.

3. Features of the synchronous lift:

1. High quality and simplified design, compact components, strong durability. It can be assembled according to the designer's requirements, reducing design time.

2. Model selection: When selecting a model, different models should be chosen based on load, stroke, and series.

3. Selection of shaft spacing: When selecting, note that if the shaft spacing exceeds the corresponding length, intermediate support should be added.

4. Smooth and quiet operation during up/down motion. The gear and rack structure ensures precise meshing, maintaining synchronization even in harsh environments.

4. Wide range of applications:

Suitable for automated production line assembly processes or logistics lines, automated warehouses, automated photovoltaic production lines, and other general industrial machinery equipment.

5. Applications of the synchronous lift:

Standard model / Cleanroom model

Flat lifting / General lifts / FPD conveyor lifting equipment

Lifting transmission for conveyors / Glass pin lifting equipment

Lifting platforms for automated warehouse input/output / Cleanroom lifting equipment

Lifting for other automated machinery and industrial machines / Food manufacturing equipment
