Abstract

A hydraulic rotary motor, in particular to a stewing gear for elevating plant such as excavator grabs, etc., comprising a housing in which a rotor is rotatably received as well as a ring piston having an inner toothed arrangement and an outer toothed arrangement which is seated between the rotor and the housing so that displacement chambers are formed between the ring piston and an outer toothed arrangement of the rotor and / or an inner toothed arrangement of the housing, with a first motor connector being rotatably fixedly connected to the housing and a second motor connector being rotatably fixedly connected to the rotor. The hydraulic rotary motor is characterized in that the rotor is axially and radially supported at the housing via plain bearings and the second motor connector connected to the rotor is solely supported via the plain bearings at the housing.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a hydraulic rotary motor, in particular to a slewing gear for elevating plant such as excavator grabs, etc., comprising a housing in which a rotor is rotatably received as well as a ring piston having an inner toothed arrangement and an outer toothed arrangement which is seated between the rotor and the housing so that displacement chambers which can be filled with pressure fluid are formed between the ring piston and an outer toothed arrangement of the rotor and / or an inner toothed arrangement of the housing, with a first motor connector being rotatably fixedly connected to the housing and a second motor connector being rotatably fixedly connected to the rotor.

[0003] 2. Description of the Prior Art

[0004] Such a hydraulic rotary motor is known from DE 33 42 131 A1. DE 37 29 049 C1, DE 2 365 057 or DE 196 05 879 A1 also show hydraulic rotary motors of this type in which a ring piston orbits...
