Изобретение относитс к конструкци м гидравлических двигателей, а именно к винтовым двигател м, используемым, например дл бурени нефт ных и газовых скважин.The invention relates to hydraulic engine designs, in particular to screw engines used, for example, for drilling oil and gas wells.
В известных винтовых забойных гидравлических двигател х, рабочие органы которых (ротор и статор с эластичной обкладкой) выполнены в виде винтовых шестерен внутреннего зацеплени с разницей в числе зубьев, равной единице, радиальные нагрузки воепринимаютс эластичной обкладкой статора, что приводит к значительной радиальной деформации обкладки, снижа долговечность и перегрузочную способность двигател .In well-known screw downhole hydraulic motors, the working bodies of which (rotor and stator with elastic lining) are made in the form of internal gears with internal teeth with a difference in the number of teeth equal to one, the radial loads are adopted by the elastic stator lining, which leads to a significant radial deformation of the lining, reducing the durability and overload capacity of the engine.
В предлагаемом двигателе дл устранени указанного недостатка ротор снабжен на концах цилиндрическими катками, взаимодействующими с цилиндрическими поверхност ми корпуса, причем диаметры катков и цилиндрических поверхностей корпуса пропорциональны начальным окружност м статора и ротора.In the proposed engine for eliminating this drawback, the rotor is provided at the ends with cylindrical rollers interacting with the cylindrical surfaces of the housing, the diameters of the rollers and the cylindrical surfaces of the housing being proportional to the initial stator and rotor circumferences.
Такое выполнение двигател приводит к уменьшению радиальной деформации обкладки статора, повышает долговечность и перегрузочную способность двигател .This embodiment of the engine leads to a decrease in the radial deformation of the stator plate, increases the durability and overload capacity of the engine.
На фиг. 1 схематично изображен винтовой двигатель,, продольный разрез; на фиг. 2 - разрез по А-А на фиг. 1 и начальные окружности зацеплени ротора и статора.FIG. 1 schematically shows a screw engine, a longitudinal section; in fig. 2 is a section along A-A in FIG. 1 and the initial engagement circles of the rotor and stator.
Винтовой двигатель имеет корпус 1, внутри которого неподвижно установлен статор 2 с эластичной обкладкой 3. Внутри статора эксцентрично размещен ротор 4, винтова рабоча поверхность которого находитс в зацеплении с обкладкой статора. На концах ротора установлены цилиндрические катки 5, которые обкатываютс по цилиндрическим внутренним поверхност м 6 корпуса.The screw motor has a housing 1, inside which the stator 2 is fixedly mounted with an elastic lining 3. A rotor 4 is placed eccentrically inside the stator, the screw of which has a working surface meshes with the stator lining. At the ends of the rotor, cylindrical rollers 5 are installed, which run around the cylindrical inner surfaces 6 of the housing.
При работе винтового двигател радиальные нагрузки, возникающие от действи гидравлических и инерционных сил, будут восприниматьс не только эластичной обкладкой статора, но и парой «каток - цилиндрическа поверхность корпуса.When a screw engine is operating, the radial loads arising from the action of hydraulic and inertial forces will be perceived not only by the elastic stator lining, but also by the pair of roller - cylindrical body surface.
