Abstract

본고안은 유체이송에 사용되는 유압펌프용 헬리컬기어 치형에 관한것이다.
본고안은 접촉면이 선좌측으로 작동하여 저소음,저마찰력으로인한
내구성의 증가,고 토출량이 특징이다.

Description

유압펌프용 헬리컬기어 치형 {HELICAL GEAR TOOTH}
일반기어치형은 선접촉으로 이루어지며 소음이 많고 유량손실이 커서
토출량이 적다.
본고안은 접촉면이 선좌측으로 작동하여 저소음,저마찰력으로인한
내구성의 증가,고 토출량이 목적이다.
도1 은 유압 펌프용 헬리컬기어 치형의 도면
도1 의 첩촉면을 곡선 처리한 R 치형.
접촉면이 선좌측으로 작동하는 R치형은 저소음,저마찰력으로 마모가 적고
압력을 증가시켜 고 토출량과 유량 손실이 적은 것이 특징이다.
