FIELD: engines and pumps. ^ SUBSTANCE: invention relates to rotor-type positive-displacement hydraulic machines and can be used in general machine building. Proposed hydromotor comprises guide 1 with its mounts accommodating inserted teeth 2 with inner rods made up of two parts 8 fitted inside tooth sleeve 7 to form chamber 9 there between. It includes also gear 3, spool-type device 4, covers 5 and 6, and elastic deformation limiters 10 of sleeves 7. Said limiters represent cylindrical rollers with diametre smaller than sleeve OD by amount of designed elastic deformation, arranged in cavities between parts 8 of the sleeve inner rods. Proposed design of hydromotor, in the case of excess torque, allows sleeves 7 to rest upon aforesaid limiters 10 and the tooth to operated as a single unit. ^ EFFECT: hydromotor overload protection. ^ 1 dwg |
