bauma Hall A4 stand 214
Alpha Gymnastics shows the newly developed standard program to build rotors that are available in three sizes depending 10 AR, AR and AR 15 25 of tons of excavators available. The integrated 4-point bearing absorbs all axial and radial forces and the resulting tilting. By the mechanical separation of the main storage and the hydraulic rotary joint tightness is ensured even in extreme missions for a long time. The fixing screws for mounting and receiving devices are constructed so that they have an optimal elongation length and thereby can not solve during the operation.
The plan consists of distribution hardened ground flat surfaces. He is compared to the power spreader temperature insensitive and ensures minimal leakage losses at maximum lifespan. The rotators are of a radially disposed role piston actuator driven with case hardened cam track, which ensures a high starting torque and good braking. This leads especially at low engine speeds to less internal leakage than the case of drives for the gerotor or vane principle.
The rotary unions with up to five fluid lines has induction hardened seal running surfaces on the stator, rotor seals to 500 bar and large sizes. The rotators are suitable for various stationary and mobile construction equipment and special construction vehicles. The oil distributor and suspensions are supplied according to customer.
