The RK bevel gear box-1 stair is a right-angle power transmission terminal utilizing a precision Gleason spiral bevel gear set. It is designed for industrial applications requiring 90° direction change, moderate reduction ratios, and high transmission efficiency – widely used in conveyors, packaging machinery, mixers, valve actuators, and agricultural equipment. The housing is made of high-quality cast iron or aluminum alloy. The internal bevel gear pair is case-hardened and ground, with contact patterns optimized by computer-aided design, ensuring smooth operation, high load capacity, and low noise. The unit supports dual-output (single input, dual output) or single-output configurations, and various mounting orientations, accommodating standard motors, servo motors, or hydraulic motors. The RK/2CK series integrates “right-angle turning, high efficiency, compact installation, and multi-shaft adaptability” into a 4-in-1 power module.

1. High-Precision Spiral Bevel Gear Set : Adopts Gleason-type equal-height or tapered teeth. Made of 20CrMnTi or 20CrMo steel, case-hardened to HRC58-62, with ground tooth profiles achieving grade 6-7 accuracy. Smooth meshing, noise level below 75 dB.

2. High Efficiency & Low Backlash : Single-stage bevel gear efficiency reaches 92%-96% (depending on lubrication and ratio). Standard backlash is 5-8 arc-minutes; precision grade (≤3 arc-minutes) available for servo positioning.

3. Flexible Shaft Configurations & Mounting : Input and output shafts at 90°. Available in single-input/single-output or single-input/dual-output (same or opposite rotation). Housing provides multiple mounting faces, supporting M1 to M6 mounting orientations.

4. Reliable Sealing & Long-Life Lubrication : Shaft ends feature double-lipped oil seals (FKM or NBR optional) combined with labyrinth dust protection, achieving IP65 protection. Pre-filled with synthetic gear oil (ISO VG220 or 320) – maintenance-free for up to 10,000 hours under normal conditions.

5. Compact & Lightweight Design : Topology-optimized housing reduces weight by 15-20% compared to traditional bevel gearboxes, saving installation space.
