Bevel Gear Screw Jack
What is a Bevel Gear Screw Jack?
The bevel gear screw jack (also known as a spiral bevel gear screw jack) is a compact, high-efficiency modular lifting and hoisting device. It utilizes a spiral bevel gear transmission structure to replace the traditional worm gear structure, completely solving industry pain points such as low efficiency, rapid temperature rise, short lifespan, and limited speed adjustment of traditional screw jacks. The equipment can achieve precise lifting, lowering, pushing, tilting, leveling, and positioning movements, supporting both independent single-unit operation and synchronous multi-unit operation. It is widely applicable to high-end scenarios such as industrial automation, metallurgical equipment, warehousing and logistics, precision machine tools, aerospace tooling, and new energy equipment.

Features
- High transmission efficiency, energy saving and consumption reduction: Utilizing precision spiral bevel gear meshing transmission, transmission loss is extremely low. The overall efficiency is more than 30% higher than that of worm gear screw jacks. The maximum input speed can reach 500 r/min, and the lifting speed can reach 2.7 m/min. High-speed operation is stable and without jamming, effectively reducing equipment energy consumption and operating costs over long-term use.
- Longer lifespan and stronger stability: The gears are made of high-strength alloy steel with carburizing and quenching treatment, and the screw is precision ground, making it wear-resistant and fatigue-resistant, eliminating wear and jamming problems during long-term heavy-load operation. The machine has a compact structure, sufficient rigidity, and no loosening gaps, resulting in an extremely low failure rate during continuous operation, suitable for 24-hour uninterrupted industrial conditions.
- Low noise and quiet operation, green operation: The bevel gears are made with precision grinding technology, ensuring smooth and stable meshing. There is no impact noise during operation, and the overall noise level is below 60 decibels, making it suitable for harsh environments such as laboratories, precision workshops, and cleanrooms.

Product Structure and Working Principle
1. Core Structural Components
The core of the bevel gear screw jack consists of six main components: a spiral bevel gear pair, a precision screw, a high-strength nut, precision bearings, an integrated housing, and dustproof protective components. The housing is made of high-strength cast iron, ensuring high rigidity, impact resistance, and resistance to deformation. Both the gears and screw undergo precision heat treatment and grinding, achieving high-level industrial precision, structurally guaranteeing equipment stability and service life.
2. Power Transmission Principle
The power transmission path is clear and efficient: Power source (motor/manual) → driving bevel gear → driven bevel gear reversing and reducing speed → driving screw rotation → screw nut axial linear movement → driving the load to complete lifting, pushing, and leveling actions. Through the 90° reversing transmission design of the bevel gears, vertical power conversion is achieved, significantly saving installation space while ensuring lossless power transmission and fast response. Among them, the trapezoidal screw model features self-locking safety, heavy-duty durability, and high cost performance, making it suitable for low-speed heavy-duty and static pressure-holding scenarios; the ball screw model features high speed and efficiency, ultra-high precision, and low friction, making it suitable for high-frequency start-stop, precision positioning, and high-speed operation automation scenarios.

FAQ
Q1: Can multiple bevel gear screw jacks be used synchronously?
A1: Yes. This series of screw jacks supports synchronous operation of 2, 4, 6, and more units. They can be used with synchronous drive shafts and servo control systems, offering high synchronization accuracy and smooth operation. They are widely used in large lifting platforms and for leveling entire platforms.
Q2: Does the machine support customized stroke and installation method?
A2: Yes. We can customize non-standard strokes, special mounting flanges, and integrated motors with special voltages according to the customer's equipment space, lifting stroke, installation angle, and load requirements.
Q3: What are the daily maintenance requirements for screw jacks? What is the maintenance cycle?
A3: This series of bevel gear screw jacks is wear-resistant, durable, and extremely maintenance-free, making daily maintenance very simple: under normal operating conditions, check the gearbox lubricating oil level and the cleanliness of the screw surface every 6-12 months; the sealed structure effectively prevents dust and impurities from entering, eliminating the need for frequent disassembly and maintenance. Compared to traditional worm gear screw jacks that require frequent oil changes and inspection of worn parts, this significantly saves on later maintenance time and costs, making it suitable for long-term continuous operation.
