WHX Worm Gear ReducerModel and representation method

Product introduction

WHX Worm Gear ReducerMeet the JB2318-79 standard.

It is a power transmission mechanism that uses a gear speed converter to reduce the number of revolutions of the motor to all revolutions and obtain a larger torque.

It is composed of a pair or several pairs of meshing gears, worm gears and worms installed in a rigid sealed box. WHX-arc-tooth cylindrical worm reducer with the worm under the worm wheel

Features

1. The tooth surface has high strength and high bearing capacity.useA cylindrical worm with an arc-shaped shaft section. The tooth profile of the worm gear and the worm are conjugated to the arc. Because the worm gear and the worm are in convex-concave meshing, the majority of the meshing zone has a large comprehensive radius of curvature, which reduces the stress on the tooth surface and increases The tooth surface strength is improved, and the load-carrying capacity is improved.

2.The worm gear tooth root has high bending strength and high transmission capacity.The tooth profile reasonably thins the worm tooth thickness and increases the worm gear tooth root thickness, so the bending strength of the worm gear tooth root is increased, and the transmission capacity is increased.

3.High efficiency and low temperature.The angle between the contact line and the circumferential speed is mostly between 40° and 90°, which is easy to form liquid lubrication, and the friction coefficient between the tooth surfaces is small.

4. The rotation ratio is large, and it is more compact than the cross-axis helical gear mechanism.

5. It has self-locking and large safety factor.When the lead angle of the worm is less than the equivalent friction angle between the meshing gear teeth, the mechanism is self-locking and can realize reverse self-locking, that is, only the worm can drive the steam wheel, and the worm cannot drive the worm.

6. When the worm and the worm gear are meshed, the angle between the direction of the instantaneous contact line and the sliding direction is large, which is easy to form and maintain an oil film, has a small friction coefficient, small tooth surface wear, and high transmission efficiency.

Use range

WH worm gear reducerSuitable for working temperature-40%℃ -40℃.When the working environment temperature is lower than 0°C, the lubricating oil must be heated to above 0°C before starting.

It is widely used in various industries, such as petroleum, environmental protection, chemical industry, cement, transportation, textile, pharmaceutical, food, printing, lifting, mining, metallurgy, construction, power generation, etc.
