Model meaning and installation features of WPDZ80-30-B worm gear reducer

WPDZ80-30-B is a vertical, single-stage, cast iron worm gear reducer, which belongs to the domestic standard WP series and is commonly used in small and medium-sized equipment that requires large reduction ratios, smooth transmission and self-locking.

1. Model meaning (WP series standard)

W: Worm (worm gear)

P: Plane (plane cabinet, WP series)

D: Foot installation (with base)

Z: Vertical (input shaft flange upward, motor directly connected)

80: Center distance (distance between worm axis and worm gear axis) = 80 mm

30: Nominal reduction ratio = 30:1

B: Dual-axis output (standard type is A: single-axis output; B: dual-axis output)

2. Installation features and practical key points

‌1. Base type rigid installation‌This
model is equipped with a foot plate as standard. During installation, the reducer needs to be firmly fixed on the concrete foundation or steel frame through anchor bolts.

‌Operation Points‌: The base plane must be flat to prevent the deformation of the box from causing bearing damage. In humid areas like Wuxi, it is recommended to install anti-vibration pads between the feet and the foundation to cushion vibrations and isolate ground moisture.

‌Alignment requirements‌: When connecting the motor and the reducer, the concentricity of the two axes must be ensured. Excessive error will cause rapid wear and oil leakage of the oil seal.

‌2. Flexible configuration of shaft position‌Although
the standard type is vertical, the WPDZ series supports multiple input and output shaft direction combinations (such as input shaft up/down, output shaft left/right).

‌Installation Tips‌: If the on-site space is limited and the axial direction needs to be changed, be sure to confirm whether the lubricating oil level meets the lubrication requirements in the new attitude to prevent dry wear of the upper part of the worm gear due to lack of oil.

‌3. Multi-stage combination scalability‌
In scenarios that require a large transmission ratio, 2-3 reducers can be connected in series to form a multi-stage reduction system.

‌Application Suggestion‌: During combined installation, an additional intermediate support frame is required to avoid resonance caused by too long cantilevers, which is especially common in heavy-duty conveyor lines.
