Embodiment

The utility model is described further below with reference to embodiment referring to Fig. 1～3.

The utility model relates to a kind of hydraulic pressure installation, particularly a kind of diffluence motor, comprise oil hydraulic motor 1, be arranged on oil hydraulic motor 1 go out relief valve 7 on the oil pocket with one-way valve 8, be arranged on the synchronizing shaft in the diffluence motor 13, and the manifold block 2 that matches with oil hydraulic motor 1, it is characterized in that: have 3～10 parallel manifold blocks 2 of arranging, and be provided with oil hydraulic motor 1 between two manifold blocks 2, securing means arranged, constitute diffluence motor 13 each manifold block 2 and oil hydraulic motor 1 series connection.

The pumping plant high pressure oil is dispensed to each oil hydraulic motor 1 through filler opening 12, and each motor carries out run-in synchronism under the restriction of series connection splined shaft 4, and the hydraulic oil of capacity such as output is delivered to external homalographic oil hydraulic cylinder through oil outlet 11 respectively.The internal drainage of each motor arrives pumping plant by the draining road junction 15 of UNICOM.

When the oil cylinder of reaching home in advance stopped stroke, the plug-in mounting relief valve 7 on this oil circuit was opened overflow, and diffluence motor 13 is played a protective role, and makes whole synchronizer can continue operation.Because external pressure limiting one-way valve 8 set pressures are higher than one-way valve 8 set pressures on the oil circuit pipe 14, the fluid that overflows replenishes by 8 pairs of low oil pockets of load of one-way valve, and keeps the pressure minimum in inner each chamber of synchronizer.

The number of oil hydraulic motor 1 and manifold block 2 can make up according to different usage requirements, realizes that multichannel is synchronous.

Described one-way valve 8 can select for use Beijing Hua De company to produce, and model is the one-way valve of RVP6.

Described relief valve 7 can select for use Beijing Hua De company to produce, and model is the straight ejector half relief valve of DBDH6P (G).

And corresponding filler opening 12, oil outlet 11 and drain tap connects on the filler opening 12 that has on the oil hydraulic motor 1, oil outlet 11 and drain tap and the manifold block 2, and the filler opening 12 on each manifold block 2 is communicated with by oiling valve piece 10; Oil outlet 11 on each manifold block 2 and drain tap are communicated with respectively by outlet valve piece 9.

Further technological scheme can be that described oil hydraulic motor 1 is a ball piston type hydraulic motor.

Discharge capacity ball-and-spigot inner curve radial motor such as select for use, this motor volume is little, and is in light weight, simple in structure, and each motor volumetric efficiency error is little, and it is big to adapt to speed range, and low-speed running is steady.

Further also can to make described securing means be the connecting screw rod 5 that runs through each manifold block 2 and oil hydraulic motor 1 to technological scheme, has end cap 3 to be arranged on an end of diffluence motor 13 and fix by nut.

Each manifold block 2 and oil hydraulic motor 1 are fastening by connecting screw rod 5, compact structure, firm.

And described synchronizing shaft is to be made of splined shaft 4 end-to-ends, and this synchronizing shaft runs through each manifold block 2 and oil hydraulic motor 1, and the one end is arranged in the end cap 3, and the other end matches with the manifold block 2 of diffluence motor 13 afterbodys.

Synchronizing shaft is connected and composed by each splined shaft 4 head and the tail successively, and synchronizing shaft makes the synchronization of each oil hydraulic motor 1.

And internal spline on each oil hydraulic motor 1 output terminal and corresponding splined shaft 4 connections, have elastic part 6 between synchronizing shaft and the end cap 3.

Internal spline on the motor output end and corresponding splined shaft 4 connects, and each motor is realized synchronous speed, the synchronization accuracy height under splined shaft 4 joins end to end the control of the synchronizing shaft that constitutes.

This elastic part 6 can be a spring, can guarantee that each splined shaft 4 has that enough axial internal clearancies are unlikely again to stretch out long generation friction.

The bottom that further technological scheme can also be a diffluence motor 13 is connected with base 16.

In diffluence motor 13 bottoms base 16 is set, can be installed in arbitrarily on the attachment face of different amount, using scope is wide.
