Starter having plurality of mounting angles
DCFirst Claim
1. A starter mounting system having a plurality of starter mounting angles for configurably engaging a starter with a selected one of a variety of engines which have respective ring gears, said starter configurably engaging a first ring gear of a first engine at a first mounting angle, and configurably engaging a second ring car of a second engine at a second mounting angle, said first mounting angle being different from said second mounting angle, said first and said second engine each having respective engine holes for mounting said starter, said starter mounting system comprising:
- a starter body including;
a motor,an output shaft disposed coaxially with a rotating shaft of said motor,a planetary reduction mechanism transmitting rotation of said motor to said output shaft,a pinion provided such that it is capable of reciprocating movement in the axial dimension of said output shaft and engaging said respective ring gear,an overrunning clutch transmitting rotation of said output shaft to said pinion,a contact separating means for separating said pinion from said ring gear,an overhang type metallic front housing housing at least said output shaft and said overrunning clutch of the aforementioned component parts, said front housing having a plurality of front housing holes at an outer periphery thereof and a spigot joint, anda bearing, fitted inside said spigot joint of said front housing and slidably contacting and supporting an outer peripheral portion of a pinion moving body which is integral with a clutch inner of said overrunning clutch; and
a plurality of selectable metallic flange members, each flange member having a central hole for said spigot joint, a respective thickness, an engine mounting section for mounting to said engine at said engine holes, and a front housing mounting section for mounting to said front housing at said front housing holes respectively, said front housing mounting section of said each flange member having a plurality of flange member holes greater in number than said plurality of front housing holes;
wherein when said selected one of said variety of said engines is said first engine, said engine mounting section of said each flange member of said starter mounts to said first engine at said engine holes thereof, said front housing mounts to said front housing mounting section of said each flange member such that ones of said plurality of front housing holes align with ones of said plurality of flange member holes in a first mounting arrangement, and said first mounting arrangement causes said starter to have said first mounting angle;
wherein when said selected one of said variety of said engines is said second engine, said engine mounting section of said each flange member of said starter mounts to said second engine at said engine holes thereof, said front housing mounts to said front housing mounting section of said each flange member such that ones of said plurality of front housing holes align with ones of said plurality of flange member holes in a second mounting arrangement, and said second mounting arrangement causes said starter to have said second mounting angle; and
wherein one of said plurality of selectable metallic flange members is selected so that said respective thickness of said selected flange member determines a distance between said pinion and a mounting surface of said selected one of said variety of engines.

Abstract
A starter in which a flange member is mounted to the starter body in accordance with the mounting conditions of the engine. An output shaft is disposed coaxially with the rotating shaft of the motor, and a front housing of the overhang type is used. Changing the mounting angle does not change the position of the motor, so that by simply replacing the flange member, a common front housing can be used to allow mounting in accordance with a larger number of mounting conditions. In addition, the tabular shape of the flange member allows die costs to be reduced.
