Products Description
Screw bevel gearbox is an all-in-one right-angle gear unit integrating spiral bevel gear reversing mechanism and screw drive assembly. The screw bevel gearbox transfers side rotary power through 90-degree bevel gear redirection to directly drive the screw for linear push and pull motion. Different from split solutions with separate bevel gearbox and external screw, the screw bevel gearbox completes direction change and screw drive inside a single housing, eliminating intermediate couplings and brackets. It supports handwheel or motor drive with optional trapezoidal screw and ball screw. It can work as a single unit for leveling and lifting, or be chained by drive shafts for multi-point synchronous lifting. As a compact mechanical linear drive unit, screw bevel gearbox is widely used in automation tooling adjustment, test frame lifting, new energy assembly equipment and mold pressing mechanisms. It targets machinery designs with tight internal space requiring right-angle power transfer plus linear output.
Product Characteristics
Integrated Housing for Bevel Gear Redirection and Screw Drive
The screw bevel gearbox encapsulates spiral bevel gear set and screw drive components within one cast housing. No standalone miter gearbox installation is required. The screw bevel gearbox cuts intermediate transmission connectors and reduces coaxial misalignment risks during assembly.
Smooth Meshing Spiral Bevel Gear Set
The screw bevel gearbox adopts high-precision spiral bevel gear pair with large tooth contact area and even load distribution. The screw bevel gearbox steadily withstands cyclic alternating torque and fits frequent reciprocating lifting cycles.
Two Screw Motion Configurations Available
The screw bevel gearbox offers translating screw type and travelling nut type. Travelling nut version keeps the screw stationary without outward extension. The screw bevel gearbox solves structural interference issues where protruding screw is not allowed inside machinery.
Product advantages
Fewer Transmission Components & Lower BOM Cost
The integrated screw bevel gearbox replaces split bevel gearbox and screw combination. Couplings and connecting brackets are no longer needed. The screw bevel gearbox reduces part varieties and lowers total procurement cost of the whole lifting mechanism.
Compact Footprint for Embedded Machine Layout
With integrated right-angle structure and side power entry, screw bevel gearbox features compact axial dimension. Compared with split designs, the screw bevel gearbox can be embedded into narrow frame cavities and simplifies overall mechanical layout.
Minimized Transmission Backlash for Better Repeat Positioning
The screw bevel gearbox has a short internal transmission chain with fewer connecting joints, which reduces accumulated backlash. The screw bevel gearbox delivers superior position stability for precision leveling and fixture positioning tasks.

FAQ
Q: What is the main difference between screw bevel gearbox and separate bevel gearbox plus screw assembly?
A: Screw bevel gearbox is a complete integrated assembly with bevel gearbox and screw built together. Split solution requires separate purchase of bevel gearbox, screw, couplings and brackets. Screw bevel gearbox removes on-site alignment work and reduces part count.
Q: Can screw bevel gearbox handle both lifting and clamping applications?
A: Yes. The spiral bevel gear of screw bevel gearbox transmits torque bi-directionally. It can lift loads upward and deliver continuous downward clamping force. A torque limiter is recommended for clamping duty to protect screw bevel gearbox from overload damage.
Q: Does screw bevel gearbox have self-locking capability?
A: The bevel gear structure itself cannot hold load. Self-locking of screw bevel gearbox comes from trapezoidal screw. Ball screw version has no self-locking and must use brake motor to avoid unexpected load dropping.
