Abstract
A gear device with at least one rotating structural component, with a further structural component that delimits at least one supply area and with at least one consumption point that is to be supplied with hydraulic fluid via the supply area. Hydraulic fluid from at least one hydraulic fluid supply device can be introduced into the at least supply area via at least one supply opening, and can be discharged via at least one outlet opening from the at least one supply area for supplying the at least one consumption point. Inside the supply area, at least one pumping appliance driven by the structural component is provided for transporting hydraulic fluid from the at least one supply opening in the direction of the at least one outlet opening.
Claims17
A gear device, comprising:
- a rotatable structural component,
- a further structural component that delimits a supply area,
- a consumption point that is to be supplied with hydraulic fluid via the supply area,
- wherein hydraulic fluid from a hydraulic fluid supply device is introduced into the supply area via a supply opening, and is discharged via an outlet opening from the supply area for supplying the consumption point,
- at least one pumping appliance driven by the structural component and positioned inside the supply area for transporting the hydraulic fluid from the supply opening in a direction of the outlet opening;
- a spline connection connecting the at least one pumping appliance to the structural component, and a bearing appliance mounting the at least one pumping appliance with respect to a further rotatable structural component of the gear device.
A gear device, comprising:
- a rotatable structural component,
- a further structural component that delimits a supply area,
- a consumption point that is to be supplied with hydraulic fluid via the supply area,
- wherein hydraulic fluid from a hydraulic fluid supply device is introduced into the supply area via a supply opening, and is discharged via an outlet opening from the supply area for supplying the consumption point,
- at least one pumping appliance driven by the structural component and positioned inside the supply area for transporting the hydraulic fluid from the supply opening in a direction of the outlet opening;
- wherein the at least one pumping appliance includes multiple pumping appliances arranged in the supply area behind each other in a flow direction of the hydraulic fluid.
A gear device, comprising:
- a rotatable structural component,
- a further structural component that delimits a supply area,
- a consumption point that is to be supplied with hydraulic fluid via the supply area,
- wherein hydraulic fluid from a hydraulic fluid supply device is introduced into the supply area via a supply opening, and is discharged via an outlet opening from the supply area for supplying the consumption point,
- at least one pumping appliance driven by the structural component and positioned inside the supply area for transporting the hydraulic fluid from the supply opening in a direction of the outlet opening;
- a pressure recovery appliance arranged downstream of the at least one pumping appliance;
- wherein the pressure recovery appliance includes a further impeller that is connected to the further structural component in a torque-proof manner and contains the impeller.
