Abstract

Изобретение относитс к машиностроению, в частности к реечным передачам, и может быть использовано в различных машинах и механизмах, где примен етс передача зубчатое колесо-рейка. Цель изобретени - повышение эффективности смазки. Дл получени положительного эффекта полость цилиндра 6, в котором перемещаетс закрепленный на конце рейки 3 поршень 7, сообщаетс трубопроводами 8 и 10 соответственно с резервуаром 2 дл жидкой смазки и смазываемыми детал ми 11 передачи. Дл увеличени числа смазываемых деталей цилиндр 6 и поршень 7 могут быть выполнены ступенчатыми по длине. 2 з.п. ф-лы, 2 ил.The invention relates to mechanical engineering, in particular, to rack and pinion gears, and can be used in various machines and mechanisms where a toothed gear is used. The purpose of the invention is to increase the efficiency of the lubricant. To obtain a positive effect, the cavity of the cylinder 6, in which the piston 7 fixed at the end of the rail 3 moves, is connected by pipelines 8 and 10, respectively, to the liquid lubricant reservoir 2 and the lubricated transmission parts 11. To increase the number of parts to be lubricated, the cylinder 6 and the piston 7 can be made stepwise in length. 2 hp f-ly, 2 ill.

Claims

Claim

1. Rack and pinion transmission, comprising a housing with a reservoir for liquid lubricant, mounted in the housing with the possibility of reciprocating movement of the rack, a gear wheel interacting with the rack, a piston cylinder, the cavity of which is in communication with the body, and the piston is fixed at the end of the rack, and the pipeline, one the end of which is connected to the reservoir, characterized in that, in order to increase the efficiency of lubrication, the other end of the pipeline is in communication with the cylinder cavity, and the gear is equipped with a check valve installed on the pipeline, and additional the pipeline, one end of which is in communication with the cylinder cavity, and the other is facing the lubricated parts of the transmission.

2. The transmission according to p. ^ Characterized in that the transmission is equipped with an additional non-return valve mounted on an additional pipeline.

3. The transmission according to claim 1, characterized in that, in order to increase the number of lubricated parts, the piston and cylinder are made stepwise in length, and the transmission is equipped with pipelines in the number of stages, one ends of which are in communication with the cavity of the corresponding cylinder stage, and the others in each pair respectively communicate with the reservoir and face the lubricated parts.
