German Mayr clutch Mayr model Mayr price

Mayr clutches operate on electromagnetic principles and use magnetic powder to transmit torque. They feature a basically linear relationship between excitation current and transmitted torque, can transmit a certain torque independent of slip speed, and offer advantages such as fast response, simple structure, no pollution, no noise, no shock or vibration, and energy savings. They are versatile, high-performance automatic control components. Classified by shaft type: double-shaft magnetic powder clutch, hollow shaft magnetic powder clutch, and through-hole shaft magnetic powder clutch. Classified by cooling method: self-cooled, air-cooled, and water-cooled, etc.

Mayr clutch applications and structure

Printing machinery, paper processing machinery, bag making machinery, paper making machinery, wire and cable machinery, winding machinery, wire processing machinery, bundling and packaging machinery, textile machinery, fiber machinery, woodworking machinery, test equipment, simulated load applications, precision tension control for various machinery, general industrial devices, and other general industrial machinery. The magnetic powder clutch features a cylindrical single-gap structure with slip rings. The rotor 5, which has significant inertia, is connected to the driven shaft 1 via a key. A coil 7 is installed in the annular groove on the outer edge of the rotor and sealed with a non-magnetic ring 6. The housing 4 and end covers 2, 10 form the driving assembly, which rotates on rolling bearings. Magnetic powder fills the gap between the housing and the rotor. To prevent magnetic powder leakage, thin retaining rings 9 are fixed to both ends of the rotor, and rubber oil seals 3 are used to block leaked powder from entering the rolling bearings.

Mayr clutch features

1) Magnetic powder clutches and brakes are high-performance automatic control components. 2) High linearity and high-precision torque control. 3) Uses high-temperature resistant coils and superalloy magnetic powder for long service life, smooth engagement, and shock-free operation. 4) CNC precision manufacturing ensures high accuracy, fine machining, good linearity, and superior performance. 5) High-purity magnetic powder without black carbon powder ensures stable performance and long service life. 6) Aluminum alloy construction provides excellent heat dissipation, good demagnetization, and fast response. 7) Smooth operation with no vibration, shock, or noise during start-up, running, and braking. 8) Torque is proportional to excitation current within the specified torque range, allowing use as a linear adjustment component. 9) Constant output torque, as torque magnitude depends only on excitation current and is independent of slip speed. 10) Frequent engagement/disengagement with fast response and high frequency, reaching up to 40-60 times per minute, suitable for rapid operation and high-frequency applications. 11) High power amplification ratio allows controlling large transmitted power with small excitation current, facilitating automatic control. 12) Smooth operation with no vibration, shock, or noise during start-up, running, and braking. 13) Overload protection: automatic slip operation under torque overload conditions provides overload protection. 14) Compact size and light weight. Easy installation and long service life.

Mayr clutch maintenance

1) To ensure mechanical equipment remains in good technical condition, is ready for operation at any time, reduces fault downtime, improves equipment availability and utilization, reduces wear, extends service life, lowers operating and maintenance costs, and ensures safe production, maintenance work must be strengthened. 2) Mechanical maintenance must follow the principle of 'equal emphasis on maintenance and repair, prevention first,' ensuring regular and mandatory maintenance. Properly handle the relationship between use, maintenance, and repair; operation without maintenance or repair without maintenance is not permitted. 3) All teams must perform maintenance on various types of machinery according to maintenance procedures and categories without unjustified delay. In special cases, maintenance may be postponed with approval from the responsible specialist engineer, but generally not exceeding half of the specified maintenance interval. 4) Maintenance quality must be ensured by performing each item according to specified requirements. No items should be skipped or omitted. Records of maintenance items, quality, and issues found during maintenance must be kept and reported to the department's specialist engineer. 5) Maintenance personnel and departments must implement 'three inspections and one handover' (self-inspection, mutual inspection, specialist inspection, and qualified handover), continuously summarize maintenance experience, and improve maintenance quality. 6) The Asset Management Department regularly supervises and inspects mechanical maintenance across units, conducts periodic or random checks on maintenance quality, and implements rewards and penalties.
