Description
Technical field
The utility model relates to the drawn cup needle roller bearing be used in automobile transmission, general industry equipment, Denso equipment etc.
Background technique
In automobile transmission, the bearing such as supported as the input shaft linked the output shaft with motor and the drawn cup needle roller bearing employed as shown in Figure 2.This drawn cup needle roller bearing 1 is configured to comprise: drawn cup 5, and this drawn cup is located on the periphery of the axle 2 that support, and is made up of cylindrical part 8, the lip part 6 extended inside radial direction from the axial two ends of this cylindrical part 8, thin-walled lip part 7; Be disposed in the multiple needle rollers 3 between this drawn cup 5 and axle 2; With by these needle rollers 3 along the circumferencial direction of drawn cup 5 with the retainer 4 of the cylindrical shape kept at equal intervals, the press-in of the cylindrical part 8 of drawn cup 5 is fixed on shell 9 by this drawn cup needle roller bearing 1.
In the assembling of this drawn cup needle roller bearing 1, first, be cup-shaped using the outer loop material deep-draw of the steel plate of the material as drawn cup, and punch process is carried out to bottom surface, form lip part 6 thus.After the outer ring material hardening being made this state by heat treatment, only externally the cup-shaped peristome of loop material implements annealing in process.Then, the assembly body of retainer 4 and needle rollers 3 is assembled in outer loop material, then makes the cup-shaped peristome crimping of outer loop material and form thin-walled lip part 7.
For ease of bending, thin-walled lip part 7 is thinner thickness compared with cylindrical part 8, lip part 6.
The internal diameter φ A1 of the lip part 6 of such formation is less than the outer end diameter φ B1 of lip part 6 side of retainer 4.In addition, the internal diameter φ A2 of thin-walled lip part 7 is less than the outer end diameter φ B2 of thin-walled lip part 7 side of retainer 4.Thus, even if needle rollers 3 is for moving vertically, lip part 6, thin-walled lip part 7 can contact with retainer 4, and play a role as the retainer of axis.
And, press lip part 6 in the mode making thin-walled lip part 7 side become inboard and by cylindrical part press-in to shell 9, make drawn cup needle roller bearing 1 locate thus.
But in drawn cup needle roller bearing 1, be difficult to distinguish lip part 6 and thin-walled lip part 7, pressing direction can be got wrong by worry.If get pressing direction wrong, then can press thin-walled lip part 7, worry to cause thin-walled lip part 7 to be out of shape by pressing force and produce the problem to contact with retainer 4 etc.
Model utility content
The utility model is made in view of the foregoing, its object is to, provide a kind of can so that the drawn cup needle roller bearing of mode identification of the lip part of the pressing when being pressed into can not be got wrong.
Above-mentioned purpose of the present utility model is realized by following formation.
A kind of drawn cup needle roller bearing, it forms and comprises:
Be located at the drawn cup on the periphery of the axle that support;
Be disposed in the multiple needle rollers between this drawn cup and described axle;
By described needle rollers along the circumferencial direction of described drawn cup with the retainer of the cylindrical shape kept at equal intervals, the feature of this drawn cup needle roller bearing is,
Described drawn cup is by cylindrical part, the lip part extended inside radial direction from axial one end of this cylindrical part and form from the thin-walled lip part that the axial the other end of this cylindrical part extends inside radial direction,
The internal diameter φ A1 of described lip part is less than the outer end diameter φ B1 of the lip part side of described retainer,
The internal diameter φ A2 of described thin-walled lip part is less than the outer end diameter φ B2 of the thin-walled lip part side of described retainer,
The end face outside of described lip part to be stamped having identification mark,
By the axial length L 1 of the pars convoluta that described thin-walled lip part is connected with described cylindrical part, longer than the axial length L 2 of the pars convoluta that described lip part is connected with described cylindrical part.
By adopting this structure, drawn cup needle roller bearing of the present utility model has stamp on the end face of lip part, thus, can not get lip part and thin-walled lip part wrong.In addition, even if be difficult to observe in the environment of stamp, by the visual length L1 of grasp pars convoluta, the difference of L2, therefore, pressing direction can not got wrong.
Accompanying drawing explanation
Fig. 1 is the partial sectional view of the example representing drawn cup needle roller bearing of the present utility model.
Fig. 2 is the partial sectional view of an example of the drawn cup needle roller bearing represented in the past.
Embodiment
Below, drawn cup needle roller bearing of the present utility model is illustrated with reference to accompanying drawing.
As shown in Figure 1, drawn cup needle roller bearing 10 is configured to comprise: drawn cup 15, this drawn cup 15 is located at the periphery of the axle 2 that support, and is made up of cylindrical part 18, the lip part 16 extended inside radial direction from the axial two ends of this cylindrical part 18, thin-walled lip part 17; Be disposed in the multiple needle rollers 3 between this drawn cup 15 and axle 2; With by above-mentioned needle rollers 3 along the circumferencial direction of drawn cup 15 with the retainer 4 of the cylindrical shape kept at equal intervals.
Lip part 16 is in the same manner as the lip part 6 of the drawn cup 5 of the drawn cup needle roller bearing 1 of prior art, by after outer loop material deep-draw is cup-shaped, carries out punch process formed bottom surface.
The thickness of slab of lip part 16 becomes the thickness of slab roughly the same with the thickness of slab of cylindrical part 18, and the end face outside is axially stamped having identification mark M.Graphical symbol M also can be used for the display of ProductName, production code member, Mission Number etc.
Thin-walled lip part 17 is in the same manner as the lip part 7 of the drawn cup 5 of the drawn cup needle roller bearing 1 of prior art, the assembly body of retainer 4 and needle rollers 3 is assembled in outer loop material, then makes the cup-shaped peristome crimping of outer loop material and form thin-walled lip part 17.
Now, bending is carried out in the mode making the axial length L 1 of the pars convoluta be connected with cylindrical part 18 by thin-walled lip part 17 longer than the axial length L 2 of the pars convoluta be connected with cylindrical part 18 by lip part 16.
In the scope that can not have an impact to the roller surface of needle rollers 3, to enable the difference of L1 and L2 by the visual degree distinguished, difference is paid to L1 and L2.
The internal diameter φ A1 of lip part 16 is less than the outer end diameter φ B1 of lip part 16 side of retainer 4.In addition, the internal diameter φ A2 of thin-walled lip part 17 is less than the outer end diameter φ B2 of thin-walled lip part 17 side of retainer 4.Thus, even if needle rollers 3 is for moving vertically, lip part 6, thin-walled lip part 7 can contact with retainer 4, and play a role as the retainer of axis.
Drawn cup needle roller bearing 10 is being pressed in the press-in portion of fixing shell 9, is being provided with C chamfering 21 at the inlet side be pressed into and end face outside side.In addition, when drawn cup needle roller bearing 10 is pressed into, in the mode that the inboard end face 22 of thin-walled lip part 17 and press-in portion can not be made to abut, the length L4 till end face 22 inboard from end face outside to press-in portion is set longer than the length L3 from end face outside to the end face of thin-walled lip part 17.
When being pressed into, pressing lip part 16 in the mode making thin-walled lip part 17 side become inboard and cylindrical part 18 being pressed into shell 9, making drawn cup needle roller bearing 10 locate thus.
Owing to there is stamp M on the end face of lip part 16, so lip part 16 and thin-walled lip part 17 can not be got wrong.In addition, even if be difficult under the environment observing stamp, the length L1 of pars convoluta, the difference of L2 can be being grasped by visual, therefore, pressing direction can not got wrong.In addition, L1 arranges longer, therefore, makes press-in become easy with complementing each other with C chamfering 21.
