Background technique
Starter motor is a crucial widget on the automobile, if starter motor breaks down and will cause vehicle to start, and the one-way element on the automobile starter mainly is to make starter driving gear with the engine flywheel engagement driving and separate.One-way element generally comprises planet carrier structure and sleeve, and an end of sleeve is provided with gear, and an end axial limiting that is provided with gear is installed in the housing of motor car engine, and gear is meshed with the flywheel of motor.At present; Existing automobile-used one-way element generally adopts positioning ring and Steel Cable Baffle Ring that sleeve and roller bearing location are equipped with, and the number of spare parts that this location is equipped with employing is many, and in installation process, needs to install position limit cycle and Steel Cable Baffle Ring; Complex steps, complex structure.
Summary of the invention
The purpose of the utility model is: to the deficiency of existing technology, the utility model provides the one-way element of a kind of simple in structure, good positioning effect, band spiral involute spline axially locating that reliability is high.
To achieve these goals, the utility model has adopted following technological scheme:
A kind of one-way element with spiral involute spline axially locating; Comprise support, planet carrier parts, sleeve and geared parts; Described planet carrier parts comprise planet wheel be arranged on the roller bearing on the planet wheel, described roller bearing stretches in the sleeve away from an end of planet wheel, roller bearing is provided with some equally distributed splines outward; Form spline between adjacent two splines; Described spline involute in the shape of a spiral distributes, and spline is provided with some equally distributed positive stop keys away from the roller bearing outer webs of planet wheel one side, each positive stop key respectively with one group of spline corresponding matching; Every group of spline quantity is identical; Form the spacing keyway of key between adjacent two adjacent positive stop keys, the spline that spline constituted and the corresponding spacing keyway that are positioned in the spline of two adjacent groups on the edge are positioned on the same spiral involute, and the inwall of described sleeve is provided with the interior involute splines with positive stop key quantity relative set.
As preferably, described support casing is located at outside the roller bearing, and is covered on outside the planet wheel, and described support is provided with expanding ring.
As preferably, be provided with the antifriction pad between described expanding ring and the support.
As preferably, the corresponding setting of described positive stop key with the even number spline, described roller bearing is provided with transformation segment near the planet wheel place, and described transformation segment is between spline and bottom line star-wheel, and transformation segment length and interior involute splines length are suitable.
The one-way element of the band spiral involute spline axially locating of the utility model adopts spiral involute spline, positive stop key and interior involute splines to form the location and is equipped with, and replaces the system that traditional one-way element utilizes Steel Cable Baffle Ring and positioning ring to position, and has saved component; Reduced amount of parts; Improved reliability of products, simultaneously, save Steel Cable Baffle Ring and positioning ring after; Save the process step that Steel Cable Baffle Ring and positioning ring are installed, improved manufacturing efficiency.

Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; The embodiment of the utility model specifically is a kind of one-way element with spiral involute spline axially locating, comprises support 1, planet carrier parts 2, sleeve 3 and geared parts 4, and planet carrier parts 2 comprise planet wheel 21 and are arranged on the roller bearing 22 on the planet wheel 21; Roller bearing 22 stretches in the sleeve 3 away from an end of planet wheel 21; Be provided with equally distributed spline 221 outside the roller bearing 22, form spline 222 between adjacent two splines 221, spline 221 involute in the shape of a spiral distributes; Spline 221 is provided with equally distributed positive stop key 223 away from roller bearing 22 outer webs of planet wheel 21 1 sides; Each positive stop key 223 respectively with one group of spline 221 corresponding matching, the quantity of every group of spline 221 is identical, every group is two splines 221.Form the spacing keyway 224 of key between adjacent two adjacent positive stop keys 223; Be positioned at the spline 222 that the spline 221 on the edge constituted in the spline 221 of two adjacent groups and be positioned on the same spiral involute with corresponding spacing keyway 224, the inwall of sleeve 3 is provided with the interior involute splines 31 with positive stop key 223 quantity relative set.
During installation; Internal spiral involute splines 31 in the sleeve 3 is aimed at the spacing keyway 224 on the roller bearing 22, and turnbarrel 3, internal spiral involute splines 31 is screwed in along spacing keyway 224; After internal spiral involute splines 31 screws in along spacing keyway 224; Continue the edge and be selected into spacing keyway 224 corresponding splines 222, continue turnbarrel 3, final internal spiral involute splines 31 breaks away from the transformation segment 225 that spline 222 gets in the rotating shaft.With the position of a spline 31 of sleeve 3 rotation, and the spline 222 that internal spiral involute splines 31 is aimed at along the rotation back is to inner rotary, and final internal spiral involute splines 31 forms butts with positive stop key 223, has promptly accomplished the installation of sleeve 3 with roller bearing 21.
