結(jié)構(gòu)原理
通壓力油的柱塞缸受液壓力的作用,在柱塞體上產(chǎn)生推力P。 該推力通過連桿作用在曲軸中心,使輸出軸旋轉(zhuǎn),同時配油盤隨著一起轉(zhuǎn)動,當(dāng)柱塞體所在位置到達下死點時,柱塞缸便由配油盤接通回油口,柱塞便被曲軸往上推。此時,做功后的液壓油通過配油盤返回油箱。各柱塞體依次接通高低壓力油,各柱塞體對輸出軸中心所產(chǎn)生的驅(qū)動力矩同向相加, 使馬達輸岀軸獲得連續(xù)而平穩(wěn)的回轉(zhuǎn)扭矩。當(dāng)改變油流方向 時,便可改變馬達的旋轉(zhuǎn)方向。如將配油盤轉(zhuǎn)180°裝配也可以實現(xiàn)馬達的反轉(zhuǎn)。

Product overview
The latest presented product-LDF series hydraulic motor, not only reflects our rich experience in hydraulic motor manufacture, but absorbs the advantages of cranLDhaft connecting rod hydraulic motor from both home and abroad.
Its main features
1:Static pressure balance structure between shaft joint and connecting rod, thereby, it well smoothes the fiction joint and releases shaft pressure.
2:Because of the decrease of the fiction work and heat loss, mechanical and starting efficiency increase, the work pressure of motor also improves.
3:The shaft of this series employs fission structure to prolong motor life.
4:All the key parts of this series use special material and employ special heat treatment, therefore, efficiently prolong motor life.
5:As the dimension and performance data of this series are the same as HMB series of KAWASAKI-STAFFA Company, it could replace HMB directly.
Notes
Besides those mentioned in the LD series, please also note that:
Because this series employs static pressure balance structure, the motor leakage increase accordingly. When connect drain port from outside, the inner diameter should not less than 12mm, otherwise will damage the shaft seal. Also, when connect the tie-in of the drain port, do not screw in too much.

Product overview
GM 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. GM hydraulic motor mainly has the following characteristics:
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, GM series hydraulic motor has such features as: very high mechanical efficiency and comparatively high startup torque (mechanical efficiency of over 0.92 during startup).
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).
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.
As the piston is jointed closely with bearing bushing without any clearance, this series of hydraulic motor can run at pump working condition.
This series of hydraulic motor has high pressure, (the highest pressure can reach 31.5 Mpa) light weight, small bulk and high specific power.
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 GM 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.
