Types of gear machining

Gear machining generally comprises cutting, shaping, and forming gears. Different types of gear machining services perform distinct functions and cater to specific industry requirements.

  • Gear Cutting

    The most common type of gear machining is gear cutting. It involves removing material from a workpiece to create gear teeth. Several methods make gears, including hobbing, broaching, and milling. Each method's choice depends on the gear's design, size, and volume of production.

  • Bevel Gear Machining

    Bevel gears are gears that connect shafts at angles, usually at right angles. They're often found in differentials, transmissions, and other assemblies that need to change the direction of torque. The teeth of bevel gears can be straight, spiral, or curved. Gear machining for bevel gears involves shaping the gear to factory standards and specifications and the straight bevel gear cutting methods, which include hobbing, shaving, grinding, and lapping.

  • Internal Gear Machining

    Internal gears have teeth on the inside circumference. They work like external gears but are designed to mesh with a shaft or ring located inside them. Internal gears often find applications in planetary gear systems, gearboxes, and attachments to rotating shafts. Internal gear machining typically involves CNC cutting technology or gear shaping technology, which uses computer technology to control gear shaping machinery to shape gears precisely.

  • Hobbing

    Gear hobbing is a specific type of machining that makes external gears, including spur, helical, and other similar type gears. It involves a gear cutting tool called a hob, which removes material from a workpiece to create gear teeth. Hob design and operation are complex, and machining services that use hobbing are specific to making certain types of gears with particular characteristics and requirements.

Specifications & Maintenance of Gear Machining

Specifications

  • Machine Size

    A CNC gear hobbing machine's overall dimensions, like 3,200 x 2,200 x 2,600 mm, specify the space it takes up. Such a specification matters for planning where to place the machine in a workshop or factory area. It indicates whether existing facilities can accommodate the equipment without any additions or changes to the building.

  • Cutting Tools

    A CNC gear hobbing machine uses a series of precise cutting tools to create the gear teeth. These tools include hobs, which are the main cutting instrument, as well as broaches and reamers for finishing touches. The range of different types of and sizes of cutting tools specified for the machine determines what shapes and sizes of gears can be produced.

  • Power Supply

    The machine requires a certain kind of power supply to function. This is specified in terms of voltage and current. For example, it may run on a 220/380V, 3-phase, 50Hz power system. Meeting this precise power requirement is crucial for the safe and proper operation of the gear hobbing machine. If the specified power needs are not accounted for, it could lead to equipment failure or functional issues.

Maintenance tips

  • Regular Lubrication

    Gear hobbing machines have many moving parts. Regular application of suitable machine oil is essential to keep them operating smoothly. Lubrication prevents unnecessary wear and tear caused by friction, helping to maintain the proper functioning of the equipment over time.

  • Scheduled Cleaning

    It is important to clean the gear hobbing machine on a frequent basis as per the set schedule. By removing any dust, dirt or debris buildup, this helps to preserve the machine’s optimal performance. Cleaning prevents contaminating sensitive components and keeps the equipment running efficiently. Adhering to the established regular cleaning routine is key to maintaining the longevity of the gear hobbing machine.

  • Tighten Loose Parts

    The gears and other components of the hobbing machine may become slightly loose over time through normal use. Periodically checking and re-tightening any loose parts helps maintain the proper operation of the equipment. This simple yet important maintenance task helps prevent potential issues from arising, ensuring the gear hobbing machine continues to function effectively.

Scenarios of gear machining

Gear machining shows its usefulness in various industries. Here are some typical scenarios where gear machining is applied.

  • Automotive industry

    Gear machining plays a vital role in the automotive industry. It produces different types of gears used for car engines, transmission systems, steering, and other functional parts. The gear machining centers are equipped with state-of-the-art technology to meet global requirements in quality and precision.

  • Aerospace industry

    Aerospace instruments and devices require complex gears with high-precision machining processes. They are crucial to the safety of aircraft. Many gear machining manufacturers specialize in the machining of small toothed parts that are used for satellites, equipment, and other aerospace vehicles.

  • Industrial machinery

    Gears are also essential parts to drive and control various industrial machines, such as conveyor belts, pumps, crushers, excavators, and more. They are manufactured with durable materials through specific machining processes to ensure that they can function well under heavy loads and in harsh working environments.

  • Medical equipment

    The precision levels of gears used in medical equipment are even higher than those for regular machinery. Moreover, those gears should smoothly run and be quietly operated. This puts higher demands on the machining processes.

  • Renewable energy

    Wind turbines use big gear sets that can withstand high torque to convert wind energy into electrical energy. Some gear machined parts may have resistance to harsh weather conditions so that the machines can operate stably and smoothly in outdoor environments.

  • Robotics

    Gear machining is crucial for the robotics industry, as it is responsible for machining mini and complex gears used for robots. Those gears usually feature high rotation speed and precision, and they play a pivotal role in the movement and control of robots.

  • Construction industry

    Construction equipment, such as loaders, cranes, and bulldozers, relies heavily on gears. The heavy-duty, high-torque gears function to regulate the motion of machines and provide the driving forces required.
