Abstract
The utility model discloses a position-limit mechanism of starter isolators, in particular being to suitable for spigot gear reduction starters and direct-drive starters with small dimension diameters, solves the problems that when the diameter dimension of starting gear4 getting bigger and the spigot diameter getting smaller can cause the supporting wall of the bearing house at the front end of the driving end cap thinner and the strength lower, even the space between the two not enough to arrange the supporting wall of the driving end cap. That is the kind starter can not complete supporting of the propeller shaft under the condition. The utility model is composed of an isolator, a retainer ring, screws, a locking washer and a dust cap, which is characterized in that a shaft shoulder is arranged in the isolator inner chamber, forming a position-limit mechanism with the retainer ring fixed at the front end of the starter armature propeller shaft, playing the position-limit role. The front end of the isolator inner chamber has the dust cap, playing the dustproof and aesthetic role. The length of the strater driving end cap is shortened, and the volume and the weight are reduced.
Description
Technical field:
The utility model is a kind of starter motor one-way element limit structure, especially is fit to relate to the less seam retarding starter of diameter dimension and directly drives starter motor.
Background technique:
The starter motor structure comprises that mainly casing, armature, magnetic switch, driving end cap, shift fork, one-way element, axle bumper cover parts constitute at present.When starter motor was started working, one-way element to front slide, utilized the axle bumper cover be fixed on the transmission shaft to limit its ejected position at the drive lower edge of shift fork transmission shaft, promptly overlapped when contacting the one-way element stop motion when starting gear front-end face and axle bumper.Starting gear on axle bumper cover and the one-way element constitutes limit structure simultaneously.Transmission shaft supports by driving end cap front end bearing chamber.
The starter motor of this kind structure drives end cap front end bearing chamber supporting walls needs certain thickness proof strength.Starter motor is installed on motor, because the restriction of installing space, have the situation that requires the seam end face diameter little, become big when running into starting gear 4 diameter dimensions, the seam diameter also reduces simultaneously, can cause driving end cap front end bearing chamber supporting walls attenuation intensity to diminish, even insufficient space drive the end cap supporting walls to be provided with between the two.Promptly this kind starter motor can't be finished the support to transmission shaft in this case.
Summary of the invention:
The purpose of this utility model is, solves above-mentioned existing existing problem, and a kind of starter motor one-way element limit structure is provided.
The utility model is achieved in that and comprises one-way element, back-up ring, screw, lock washer, dust cap constitutes, and it is special to be at the one-way element inner chamber shaft shoulder to be set, the back-up ring fixing with starter armature transmission shaft front end constitutes a kind of limit structure, play position-limiting action, one-way element inner chamber front end has dust cap, plays a part dustproof and attractive in appearance.
Advantage of the present utility model is that described limit stoper constitutes at the one-way element inner chamber fully, and structure is simpler, and is easy for installation.Shorten the length of starter motor driving end cap, reduced its volume, weight.
Description of drawings:
Fig. 1 structural representation of the present utility model.
Embodiment:
Describe in detail below in conjunction with accompanying drawing: as shown in the figure, omitted the starter motor part among Fig. 1; Comprise driving end cap 1, shift fork 2, one-way element 3, starting gear 4, back-up ring 5, lock washer 6, screw 7, dust cap 8 connects and composes.
Starter motor is started working, and one-way element 3 drives lower edge armature transmission shafts 10 at shift fork 2 and slides, and utilizes the limit structure that fixing back-up rings 6 constitute simultaneously before shaft shoulder 3a that one-way element 3 inner chambers are provided with and the transmission shaft 10, limits the ejected position of one-way element 3.Back-up ring 5 usefulness lock washers 6 and screw 8 are fixed on transmission shaft 10 front ends.The front is placed 9 dustproof effect of dust cap again.
