Round connecting flanges with internal splines

Product overview

As the core component of the power transmission interface between the drive axle and gearbox, precision manufacturing and robust design of circular splined flanges directly impact transmission efficiency and the stability of the entire machine. Our series of high-precision splined flanges is specifically designed for drive axles and transmissions of construction, mining, and agricultural machinery. Our specifications cover nearly 100 types and boast excellent versatility and interchangeability. Whether it's a small 3-ton loader or a 10-ton heavy-duty underground scraper, it can quickly find the appropriate splined flange for construction machinery. We offer flexible, custom manufacturing services to meet the specific needs of equipment manufacturers or end users, ensuring each high-precision splined flange precisely connects to the power system of the entire machine.

Product Features

• High precision transmission, smooth and low noise

The internal spline adopts high-precision one-time drawing and forming technology, ensuring stable processing accuracy, clear tooth shape, and uniform indexing; the tolerances of the key shape and position are strictly controlled, the transmission components are precisely aligned, the transmission is stable, the noise level is low, and the service life of the entire machine transmission system is improved, and excellent performance is still maintained under severe operating conditions.

• Full technical specifications and variations, wide range of adaptations

This Construction Machinery Spline Flange series covers nearly 100 types of internal spline specifications, including metric, imperial, and other standard tooth shapes, and is suitable for various types of construction equipment, such as 3-10-ton loaders and wheeled excavators. They can meet the needs of equipment manufacturers for batch selection, as well as equipment maintenance and replacement, and end users.

• Solid forged blank for superior strength

A solid forged blank is used, free of casting defects, and the metal is fully processed. After hardening, tempering, and localized high-frequency quenching, a wear-resistant hardened layer is formed that has excellent fatigue strength and can withstand frequent commissioning and strong impacts.

• Comprehensive Inspection, Quality Control, Controlled Quality

Before leaving the factory, the product is fully tested by high-precision instruments, 100% of the key indicators meet the requirements of the drawings, and the test data can be traced to ensure the stable quality of each part. Round connecting flanges with internal splines.

Production and quality control

Our construction machinery spline flanges carry out the entire process from blank forging to finished products on a dedicated production line. Key processes such as spline broaching, flange turning, heat treatment, etc. are performed on automated equipment to ensure consistent processing precision and batch stability. All finished products have undergone strict inspection of appearance and dimensions, and can be stored and shipped after they are qualified. For export orders, we have specially refined the process anti-corrosion treatment of the surface of high-precision spline flanges to ensure product resistance to corrosion during long-distance transportation and storage.

Selection Guide and Common Problems

To help customers quickly and accurately select the right splined flange, we have compiled the following selection guidelines:

• Confirmation of spline parameters:

Key parameters such as the spline's modulus of elasticity, the number of teeth, the clamping angle, and the distance between the crossbars of the supporting equipment must be clarified. We can precisely match these parameters to the customer's drawings or physical objects. For non-standard needs, we can offer custom solutions for the manufacture of high-precision splined flanges.

• Mounting hole size:

The mounting hole position, thrust diameter, and flange thickness must match the flange size of the gearbox or drive shaft to ensure interchangeability of installation. Our products are designed in strict accordance with international common interface standards and have good compatibility with major equipment manufacturers.

• Torque Level Matching:

Equipment with varying load capacities has varying torque requirements for splined flange bearings in engineering equipment. We can provide strength level recommendations based on the component's capacity and gear ratio to ensure prudent selection and safe operation.

Solving Common Problems

If the splines are worn, the flange end face is poorly runout, etc., it is recommended to first check the drive shaft alignment and the torque of the mounting bolts to avoid serious damage caused by improper installation. If replacement is necessary, please select the original high-precision splined flange to ensure the transmission system is restored to working order.

Professional technical services

The company has a professional foreign trade and technical support team that can provide customers with recommendations on the selection of circular splined flanges and technical connections. For non-standard specifications or special material requirements, we can coordinate the efforts of technical experts to conduct customized development to meet the needs of equipment manufacturers, supporting new models or upgrading older equipment. Quality documents, such as material reports and inspection reports, can be provided with the shipping carton in accordance with customer requirements to facilitate quality acceptance. Whether it's a bulk purchase of splined flanges for construction equipment or an urgent need for a single high-precision splined flange to replace a spare part, we can provide a quick response and professional service.
