Description

THM – SM Series – Hydraulic Motor

TH-SM series hydraulic motor is a new type of product of our company, which is based on years practical experience. The
design is improved in the foundation on the original technologies. TH-SM hydraulic motor mainly has the following
characteristics:

1. As the piston and the tilt cylinder have no side force, the piston bottom is designed to be static pressure balance. The
torsional force is transferring between the piston and the crankshaft through rolling bearing, so the friction loss during the
transferring process of force is reduced. Therefore, TH-SM series hydraulic motor has such features as: very high
mechanical efficiency and comparatively high startup torque (mechanical efficiency of over 0.92 during startup).

2. The plane distributor (patented technology)is simple and reliable with perfect seal performance and almost no leakage.
The plastic piston ring is used to seal between the piston and the tilt cylinder, so it has very high volumetric efficiency (can
be as high as 0.98).

3. As the structure of this product has reduced friction loss and enhanced the seal performance, the product has perfect
stability at low speed. It can stably run at 10r/min working condition and has big speed regulation range.

4. As the piston is jointed closely with bearing bushing without any clearance, this series of hydraulic motor can run at
pump working condition.

5. This series of hydraulic motor has high pressure, (the highest pressure can reach 31.5 Mpa) light weight, small bulk and
high specific power.

6. As this series hydraulic motor has simple structure, reasonable design and adopts bearing with big load ability, it can
work reliably and has long life and low noise; the transmission shaft allows endure radial load and the rotational direction
is reversible.

Products Application Range

As TH-SM series hydraulic motor has the above characteristics, it has wide application range. It can be applied in the
hydraulic transmission systems of various types of machinery in plastic injection machine, light industry machine,
engineering machine, metallurgical equipment, petroleum, coal mine, geological prospecting, railway, ship, environment
protection, machine tool and agricultural machine industries.
