HYDRAULIC MOTORS — RADIAL PISTON MOTORS
Hydraulic Motors — Radial Piston Motors
The Jahns radial piston motors series HMF, HMT, HMs and HMw come along with fixed displacements. Speed is dependent on the fed flow and torque by the applied pressure. The motors could be combined with hydraulic ventilated brakes and/or planetary gear reducers.
The cylinders (5 or 7) are starlike arranged around the drive shaft. The displacement is a product of the number of pistons, the piston area and the excentricity of the driving shaft. With radial piston motors high volumentric and mechanical efficiencies could be achieved.
8 motors in 4 sizes are available as standard with a range of displacement volumes between 1 in3/rev. to 9 in3/rev. All motors come with a keyed shaft or splined hollow shaft. Continuous operating pressure: 3,045 to 4,060 psi.
18 motors in 6 sizes are available as standard with a range of displacement volumes between 11 in3/rev. to 384 in3/rev. All motors come with the option of a keyed shaft, splined shaft or splined hollow shaft. Options include contact free revolution counter, hydraulically applied multi-disc brakes, valve block with integrated pressure relief and pre-fill valves. Continuous operating pressure: 3,045 to 4,060 psi.
HMF and HMT:
This new HMF product series comes in 7 sizes with the possibility of 55 different displacement volumes between 2 in3/ rev. to 262 in3/ rev. Manufactured in large batch production means that this product range of motors is competitively priced. Continuous operating pressure: 3,625 psi and max pressure to 6,090 psi. Available with different shaft configurations and revolution counter. The HMT series has higher revolution speed.
The HMZ radial piston motor comes in 2 sizes with smooth and step-less transmission. The ratio of minimum to maximum displacement volumes is between 1:2 and 1:4.
Jahns is a supplier and hydraulic motor manufacturer for various applications including construction, mechanical, marine, and industrial.
