Worm Reduction Gears MA Series

A next-generation speed reducer gear for modern era… It is possible to use Makishinko worm reduction gears in any conceivable field of power transmission through the technology and knowledge accumulated in the course of rich experience and many successes. The rich variations makes it possible to use worm reduction gears in new fields.
Worm Reduction Gears Features :
Principles : A worm gear is a type of interlocking gear composed of a worm shaft and worm wheel. The worm is shaped like a screw and the worm wheel is a type of gear machined to have a tooth profile with the same configuration. The operation of a worm gear is similar with that of a bolt and nut. The principle is the same as a nut that has been fixed so that it cannot rotate and therefore progresses in the axial direction when the bolt is turned. The design of a worm gear is thought of through the relationship between the rack and spur gear on the middle plane of the worm wheel.
Operation : In a single thread worm, when the worm shaft rotates one time, the worm wheel progresses by one tooth (rotates). In a double thread worm, the wheel progresses by two teeth.
Key points when selecting a worm reduction gears
Selection : When selecting a worm reduction gears, the procedures for selecting the correct gear are described in the manufacturer catalogs and the series and models should be selected according to those procedures. Particular care should be taken in key areas such as selecting the load index, calculating the overhang load and examining the heat rated capacity from the manufacturer.
Cautions During Use : When using a worm reduction gears, the heat produced during the initial period of use is high and running-in operation at 1/4, 1/2 and 3/4 of rated torque for eight hour periods is key to sufficiently achieving the performance of the worm reduction gears.
Maintenance And Inspection : After completing running-in operation (approximately 50 hours), it is necessary to change the lubricating oil and to change the lubricating oil after that about 1 time per year according to the operation manual provided by the manufacturer.
Applications And Examples Of Use
Worm reduction gears are used widely in a variety of industrial machinery. This includes conveyors, winches, machining equipment, amusement park equipment, stage equipment, multilevel parking garages, automatic assembly equipment, food product manufacturing equipment, medical equipment and traveling cranes. The example of the use of worm reduction gears in rotary stockers (vertical rotary automated storage), a product of Makishinko, shows the successful utilization of the features of a worm reduction gears including quiet operation in limited space, highly accurate positioning, self-locking, and dual input shafts (an optional manual driveshaft for power outages). Another example is the application of a ball screw in a worm jack.
