Jiangsu Manqi Machinery Co., Ltd., established in 2017, is a professional manufacturer specializing in gear reducers with a factory area of 10,000–30,000 square meters and an experienced team of 11–50 employees. We proudly present our Low Noise Bevel Cylindrical DBY500 Gear Reducer, designed specifically for ball mill applications. This reducer combines the advantages of bevel gear and cylindrical gear stages, delivering high torque transmission with remarkably low noise levels. As a factory-direct supplier, we offer competitive pricing and reliable quality, making it an ideal choice for mining, cement, and industrial milling operations.
Our DBY500 gear reducer features a compact and robust construction that can withstand heavy loads and harsh working conditions. The use of carburized and ground gears ensures excellent tooth surface hardness and smooth meshing, which significantly reduces noise and vibration. Below are the detailed features and technical specifications:
Low Noise Design: Helical and spiral bevel gear geometries are optimized to minimize operating noise, ensuring a quieter working environment.
High Efficiency: The gear set achieves transmission efficiency of up to 95% due to precision machining and proper lubrication.
Durable Construction: Housing is made of high-strength cast iron, providing rigidity and resistance to deformation under load.
Easy Maintenance: Designed with oil plugs, breathers, and drain ports for convenient lubrication and servicing.
Versatile Mounting: Available in horizontal and vertical configurations to suit different ball mill layouts.
Customizable Ratios: A wide range of reduction ratios from 5:1 to 20:1 (or other ratios upon request) to match various motor speeds and mill requirements.

Frequently Asked Questions
Q1: Can the DBY500 gear reducer be used for other applications besides ball mills?
A1: Yes, while it is optimized for ball mills, it can also be applied in conveyors, crushers, mixers, and other heavy industrial machinery that require low noise and high torque.
Q2: What is the typical delivery time for the DBY500?
A2: For standard configurations, delivery is within 20–30 working days. Customized orders may require 30–45 working days depending on complexity.
Q3: How do you ensure the low noise characteristic?
A3: We use precision ground gears with optimized tooth profiles, high-quality bearings, and a rigid housing design. All units are tested before shipment to meet noise specifications.
Q4: What kind of lubrication does this reducer need?
A4: Standard models use splash lubrication with industrial gear oil (e.g., ISO VG320). For high-speed or heavy-load conditions, forced oil circulation can be provided.
Q5: Is the mounting orientation fixed?
A5: No, the reducer can be supplied in horizontal or vertical mounting. Please specify your requirement when ordering.
Q6: Do you provide installation and maintenance manuals?
A6: Yes, each shipment includes a detailed user manual with installation, operation, and maintenance instructions.
