Description
(S) УСТРОЙСТВО ДЛЯ ЦЕНТРИРОВАНИЯ ПОРШНЯ , В ЦИЛИНДРЕ(S) DEVICE FOR CENTERING A PISTON IN A CYLINDER
- . . 1 Изобретение относитс к машиност ению и может быть использовано в ма логабаритных компрессорах, работающих без смазки цилиндров« Известно устройство дл центриро вани поршн в цилиндре, содержащее подпружиненные контакты Cl 3. Однако необходимость в приводе {поршн исключает возможность размещени контактов в зоне наибольшего контактного давлени , что приводит к непосредственному трению поверхности поршн по поверхности цилиндр Целью изобретени вл етс умень шение потерь на трение поршн . : Поставленна цель достигаетс тем, что устройство снабжено дополнительными подпружиненными контакта ми, радиально расположенными в цилиндре . На фиго 1 изображена схема устро ства дл центрировани поршн в цилиндре компрессора-, на фиг. 2 - устройство , вид в плане. Устройство дл центрировани поршн в цилиндре содержит подпружиненные контакты 1, размещенные в поршне 2, и дополнител1 ные подпружиненные контакты. 3| радиально расположенные в цилиндре t. Контакты 1 и 3 выполнены в виде цилиндров из твердого смазывающего материала (например, композици на основе фторопласта АФГВ или К20). В процессе работы поршневой пары на поршне 2 и цилиндре k вдоль линий соприкосновени , образуемых контактами 1 и 3 наноситс слой твердой смазки, который и обеспечивает центрирование поршн в цилиндре, не допуска пр мого контакта между поверхност ми поршн и цилиндра. При этом потери на трение поршн уменьшают с -. . 1 The invention relates to mechanical engineering and can be used in large-sized compressors operating without cylinder lubrication. A device for centering a piston in a cylinder containing spring-loaded Cl 3 contacts is known. which leads to the direct friction of the surface of the piston over the surface of the cylinder. : The goal is achieved by the fact that the device is provided with additional spring-loaded contacts radially located in the cylinder. Figo 1 shows a diagram of an arrangement for centering a piston in a cylinder of a compressor; FIG. 2 - the device, view in plan. The device for centering the piston in the cylinder contains spring-loaded contacts 1, placed in piston 2, and additional spring-loaded contacts. 3 | radially located in cylinder t. Contacts 1 and 3 are made in the form of cylinders of solid lubricant (for example, a composition based on fluoride AFGW or K20). During operation, the piston pair on piston 2 and cylinder k along the contact lines formed by contacts 1 and 3 is applied a layer of solid lubricant, which ensures the centering of the piston in the cylinder, preventing direct contact between the surfaces of the piston and the cylinder. In this case, the friction loss of the piston reduces
