SZL Series Vertical Integrated Conical Double Gearbox Manufacturer

SZL Series Vertical Integrated Conical Double Gearbox

The SZL Series Vertical Integrated Conical Double Gearbox is a high-performance gear transmission device optimized for heavy-duty vertical drive scenarios, featuring 'vertical integrated design + double-stage conical-cylindrical hard gear transmission + high impact resistance'. It integrates conical gear direction conversion and cylindrical gear torque amplification in a single housing, utilizing special tooth profile modification and enhanced heat treatment for ultra-high load capacity, compactness, and long service life. Widely used in mining machinery, metallurgical equipment, and heavy-duty conveying machinery requiring vertical power transmission in harsh conditions, it serves as a 'high-reliability power hub' for heavy-duty vertical drive systems.

Product Details

SZL Series Vertical Integrated Conical Double Gearbox Product Introduction

1. The product is designed according to JB/T9050.1-1999 specifications, consisting of a gearbox and a distribution box, serving as a specialized product for conical twin-screw gearboxes.

2. The gearbox gears are made of 20CrMnMo, processed by carburizing, quenching, and grinding, achieving grade 6 precision and hardness of HRC58-62, with low transmission noise.

3. The distribution box gears are made of 42CrMo, cut by CNC gear hobbing machines and then carburized and quenched, featuring high precision and hardness of HRC58-62, with low transmission noise.

4. Thrust bearings use top domestic brands ZHJ and DYZV, or optionally SKF, FAG, NSK as per customer requirements.

5. The gearbox housing uses HT250 material, and the distribution box housing uses QT500, with thick-wall design ensuring high stability and smooth operation. The external design aids noise reduction, heat dissipation, lubrication, and maintenance.

6. Skeleton oil seals use Taiwan TTO brand, with dual oil seals on high and low-speed shafts to prevent oil leakage.
