Abstract
The invention relates to a starting device for internal combustion engines, comprising a drive bearing (11) and a drive shaft (14), the drive shaft (14) being supported on the drive bearing (11) by a roller bearing (13). The roller bearing (13) permits relative movement with linear and rotating portions between the drive shaft (14) and the roller bearing (13). The starting device is characterized in that the roller bearing (13) comprises an outer ring (30) fixedly arranged in the drive bearing (11), and in that the outer ring has an abutment (33) to prevent displacement of the roller bearing (13) outside of the drive bearing (11).
Description
Technical field
The present invention relates to a kind of starting arrangement.
Background technique
Known various starting arrangements, its pinion rod by means of roller bearings in drive end bearing lid.The normally so-called roller bearing of this rolling bearing is needle bearing in other words.For example can enumerate German laid-open document DE 197 26 726 A1 here.Above-mentioned open source literature has also been showed the axial stop in a kind of drive end bearing; It has avoided axially shifting out of roller bearing; Find thus; In improved mode of execution with smooth continuous cylindrical hole, at the drive end bearing that is used for holding roller bearing, this bearing seldom can shift out from the drive end bearing lid.Thisly shift out the friction that between live axle and rolling element, acts on when in live axle, shifting out and cause.
Summary of the invention
Have a drive end bearing lid and a live axle by the starting arrangement that is used for internal-combustion engine of the present invention; Wherein this live axle passes through a roller bearings in said drive end bearing lid; And said rolling bearing has been realized the relative movement with straight section and rotating part between live axle and rolling bearing; It is characterized in that: said rolling bearing has an outer shroud; It is fixed in the smooth hole in the drive end bearing lid, and this outer shroud has a backstop, and it has avoided rolling bearing from the drive end bearing lid, to shift out.Advantage by starting arrangement of the present invention is a columniform smooth hole that does not have crossette continuously can also be set in the drive end bearing lid in addition be used to hold rolling bearing, and reliably avoid rolling bearing from drive end bearing, to shift out simultaneously.Can when making this rolling bearing, use a kind of nothing cutting manufacture process in addition, this nothing cutting manufacture process is lower than cover the cutting process explicit costs that carries out at drive end bearing.According to one preferred embodiment, a plurality of projections preferably are arranged on the circumference of said outer shroud evenly distributedly.
According to one preferred embodiment, on the circumference of said outer shroud, arranged a flange.
According to one preferred embodiment, said rolling bearing is a kind of roller bearing, has the outer shroud that a sheet metal is processed, and its projection or flange are integrally formed.Preferred said rolling bearing is a kind of needle bearing.
Description of drawings
Embodiment by starting arrangement of the present invention shown in the drawings.Accompanying drawing illustrates:
Fig. 1 shows a kind of longitudinal section of ignitor of IC engine,
Fig. 2 shows the enlarged view of the drive end bearing lid of the rolling bearing with one first mode of execution,
Fig. 3 shows the cut-away view by second embodiment's rolling bearing.
Embodiment
Freely stretching out shown in the longitudinal section of Fig. 1 be used for make the starting arrangement 10 of engine starting of automobile have a front wheel driving end bearing cover 11, the rolling bearing 13 of in its bearing hole 12, having packed into is used to hold a live axle 14.This live axle 14 is supporting a pinion mate 15 at front end and is being used for being combined in the unshowned ring gear of internal-combustion engine.Live axle 14 is supporting a freewheel 16 and an engaging mechanism 17 in rearward end, and this engaging mechanism 17 is activated by a starter relay 19 through a ramming stem 18.Live axle 14 rotatable and can be bearing on the output shaft 20 of starting arrangement with its engaging mechanism 17 with moving axially.On the rearward end of live axle 20, settled a planetary gear mechanism 21, on the drive end of this planetary gear mechanism 21, meshed a sun gear 22, this sun gear 22 is arranged on the rotor shaft 23 of a drive motor 24.This planetary gear mechanism 21 is contained in the housing 26 of drive motor 24 through a flexible intermediate bearing 25.
The intercepting longitudinal section partly of the front region of drive end bearing lid 11 has been shown in Fig. 2.In this drive end bearing lid 11, the rolling bearing 13 that constitutes by roller bearing of in bearing hole 12, having packed into.This rolling bearing 13 has an outer shroud 30, and rolling bearing 13 is fixedly mounted in the drive end bearing lid 11 through this outer shroud 30.This outer shroud 30 has a flange 33, and this flange 33 prevents that rolling bearing 13 from moving out from drive end bearing lid 11.This flange 33 be in this embodiment around projection.
An ignitor of IC engine is set thus; This starting arrangement has 11 and live axles 14 of a drive end bearing lid; Wherein this live axle 14 is supported in the drive end bearing lid 11 through a rolling bearing 13, and this rolling bearing 13 has been realized a kind of relative movement between live axle 14 and rolling bearing 13.This relative movement is not only carried out on the live axle direction but also in a circumferential direction in addition.This rolling bearing 13 has an outer shroud 30, and this outer shroud 30 is fixed in the drive end bearing lid 11.This outer shroud 30 has a backstop 33, and this backstop 33 avoids rolling bearing 13 from drive end bearing lid 11, to shift out.
Outer shroud 30 has a cylindrical profile, and rolling bearing 13 is packed into through this cylindrical profile in this drive end bearing lid 11.Said backstop 33 is arranged on the axial end portion of inside of sensing starting arrangement 10 of rolling bearing 13.This backstop 33 is outstanding from the cylindrical profile of outer shroud 30, and constitutes at this and outer shroud 30 one, and can be called flange 34 or projection at this.
In Fig. 3, show the enlarged view of this position with the mode of intercepting, flange 34 prevents moving axially of rolling bearing 13 on this position.In the present embodiment, flange 34 is not such as shown in Figure 2 ring-type projection.Replace the ring-type projection, a plurality of projections 36 are arranged on the circumference of outer shroud 30, these projections 36 are preferably arranged on the circumference of outer shroud 30 evenly distributedly.For example three projections 36 distribute with the angle intervals of 120 degree.Make thus in the projection shown in Fig. 3 36, promptly from the cylindrical profile of outer shroud 30 to the transition region of the axial ledge 39 of outer shroud 30, a punch die makes the part distortion of this transition region along axial a, thereby produces these projections 36.
Rolling bearing 13 is a kind of roller bearings, and preferably a kind of needle bearing has a sheet metal system outer shroud 30, and its projection 36 or flange 34 are integrally formed.
