WPEKA Worm Gear Reducers/Worm Gearbox

WPEKA worm gear reducers, also known as double reduction worm gearboxes, are advanced mechanical systems designed to deliver high torque and low-speed output for demanding industrial applications. These worm reducer gearboxes combine a single-stage worm gearbox with a universal gearbox, creating a double-stage reduction system that enhances efficiency, performance, and flexibility. The "W" in the nomenclature represents the worm gear mechanism, known for its smooth, quiet operation; "P" refers to the robust and durable box structure; "E" signifies the double-stage reduction system for higher ratios; and "A" highlights the lower input shaft configuration.

A single-stage speed ratio ranges from 1:10 to 1:60, while the double-stage system achieves ratios between 1:200 and 1:900 by multiplying two single-stage units. This makes WPEKA worm gear speed reducers ideal for high-torque, low-speed applications like conveyors, mixers, and heavy machinery. Their compact design, durability, and efficient power transmission ensure reliable performance with minimal maintenance, making them a preferred choice for industrial environments.

WPEKA Worm Gearbox Parts Production Process

The basic structure of a worm gearbox consists of a housing, worm wheel, worm, covers, shaft, bearing, fasteners, and seals. The precise processing and quality control of each component is the basis for producing a quality worm gearbox.

Housing Processing

The housing casting purchased from the casting factory will be finely finished in our housing machining center, including the big hole, small hole, and bottom foot of the housing. Then they will be moved to the CNC drilling machine for large hole, small hole, bottom foot, oil plug hole, and oil marker hole processing. After testing, they are moved into the parts warehouse.

Worm Wheel Processing

The worm wheel consists of a cast iron wheel core and a bronze wheel rim. The wheel core casting will firstly be finished on the inner hole, outer diameter, and thickness of the wheel core at our CNC lathe area. Then the copper cladding process will be carried out by the copper casting factory. Then they will be processed at our CNC machining area, processed on our hobbing machine, and finally moved into storage after inspection.

Worm Processing

Worm is a component made of steel through rough machining, thread milling machining, heat treatment machining, external cylindrical grinding machining, thread grinding, keyway milling machining, etc.

The raw steel material will be cut according to different specifications at the sawing machine processing area, then be rough machined by a CNC lathe. And our workers will conduct thread milling according to different speed ratios. After testing, they will be put into storage.

The heat treatment of the worm will be processed by a heat treatment factory, which can improve the hardness of the worm, improve the wear resistance, and extend the service life.

After that, our workers will carry out external cylindrical grinding processing on the tooth, bearing carriers, and input shaft carrier of the worm. Next will be the grinding process. The thread grinding is to make the worm wheel & worm mesh better with low noise.

Finally, they will be processed at a keyway milling machine, enabling the gearbox to connect with other parts through the shaft and key pin.

After testing, the worms will be moved into the warehouse.

Cover Processing

The covers of worm gearboxes include a big cover, an output cover, an oil marker cover, and an input cover. The cover castings will be fine machined at our CNC lathe, for the seal carrier, housing big holes connecting the carrier and bearing carriers of the big cover and output cover, and for housing small holes connecting the carrier and oil seal carriers of the oil marker cover and input cover. The precise dimensions can prevent the worm gearbox from oil leakage and overheating problems.

Finally drilling process of the covers will be done at the drilling machine processing area, enabling the covers and the housing to connect by fasteners.

After inspection, qualified covers will be put into storage.

Shaft Processing

Shaft is a component completed by steel through the process of rough machining, external cylindrical grinding machining and milling machining. Similar to worm processing, the steel is firstly cut by a sawing machine, then rough machined at the CNC lathe area, including bearing carrier, worm wheel carrier, and output shaft carrier. Then moved to the external grinding processing area for fine processing. Finally, the shafts will be milled. After testing, the shafts will be moved into the warehouse.

Bearings and Seals

Our bearings, fasteners, seals, and other accessories are supplied by well-known manufacturers, such as bearings from C&U, HRB, oil seals from NAK, SKF, and other brands. Fasteners are grade 8.8; we can upgrade the bearings, oil seals, and fasteners according to customer needs.
