Jaké jsou typy hydraulických převodovek

1. Externí převodové čerpadlo
The external gear pump consists of a housing, a driving gear, a driven gear, an end cap, etc. During the process where the driving gear drives the driven gear to rotate together, in the suction area, the teeth separate from each other, resulting in an increase in volume and a decrease in pressure, allowing hydraulic oil to enter. After rotation, the hydraulic oil is transported to the discharge area, where the gear Zuby jsou zabudovány navzájem a vynucují hydraulický olej .

2. Interní pumpy
The internal gear pump also consists of two gears, one inside and one outside, with the rotating shaft offset. The driving gear is an outer gear with a smaller diameter, which drives the outer inner wheel rim to rotate in the same direction. In the oil suction area, the space between teeth becomes larger, allowing hydraulic oil to enter. Turn to the oil discharge area, the space Mezi zuby klesá a olej je vytlačen .

3. šroubovací převodovky
The sealing chamber is composed of a shell, an active screw, and a driven screw. As it rotates, the sealing chamber moves from one end to the other, causing hydraulic oil to flow in the axial direction. The discharged hydraulic oil flow rate is fixed, independent of the screw position, with no significant pressure changes and low noise.
