Abstract
The utility model discloses a cam wheel splitter's cam, all areal distributions of cam have the support rib that has the drive curved profile, the both sides of supporting the rib have with the tower of exerting oneself on the bearing balanced resistance face of being connected that rolls, it is protruding that every both sides of resisting the face all is provided with the outer fringe that is higher than the middle part. The utility model relates to a to have the support rib resistance face of cam on global now and carry out redesign, and make it effectively fix a position bearing at the transmission in -process, the axial cluster that slows down bearing moves the phenomenon and uses wearing and tearing, the life of extension decollator.
Description
Technical field
The present invention relates to a kind of Cam splitter, be specially a kind of cam of Cam splitter.
Background technique
Patent CN200942471Y discloses a kind of inputting shaft of indexing separator and brick tower structure-improved of exerting oneself, its inputting shaft 1 is provided with a cam 2, this cam 2 side face is distributed with the ribs 21 with driving curve profile, the both sides of ribs have resistance face 211, have guide slot 22 between ribs 21, guide slot 22 comprises the entry port of forefront and the drawing-off mouth of guide slot 22 least significant end; Described tower 3 of exerting oneself is extruded with a force-output shaft 31 vertically toward side, tower 3 side face of exerting oneself has some needle bearings 32 that can be limited in cam guide slot 22 respectively that decile is arranged, described in be limited in cam guide slot 22 needle bearing 32 liang of side pressures be clipped on the resistance face 211 of guide slot 22 both sides ribs 21.
In above structure, needle bearing 32 with the rolling transmission process in resistance face 211 in do not obtain effectively spacing, its bearing case body is easy to axial motion occurs in transmission process, not only have a strong impact on the stability of transmission, most importantly needle bearing 32 frame can be caused to touch and accelerated wear test with tower 3 of exerting oneself, and then cause needle bearing 3 disabling damage, the working life of serious curtailment slicer.
Summary of the invention
For the problems referred to above, the present invention devises a kind of cam of Cam splitter, by the ribs on existing cam side face, face of resisting redesigns for it, can in transmission process effective location needle bearing, slow down the axial motion phenomenon of needle bearing and use wearing and tearing, extending the working life of slicer.
For achieving the above object, the present invention is by the following technical solutions:
A kind of cam of Cam splitter, the side face of cam is distributed with the ribs with driving curve profile, the both sides of ribs have the resistance face be connected that offsets of rolling with needle bearing on tower of exerting oneself, and it is characterized in that: the outer rim that the both sides in described each resistance face are provided with higher than middle part is protruding.
Further, above-mentioned outer rim is protruding passes through arc surface transition with the middle part in the face of resistance.
Further, the width of above-mentioned resistance face intermediate portion is greater than needle bearing width 1-2mm, and the preferred height of both sides of the edge projection is 0.1-0.3mm.
The outer rim that the both sides in each resistance face of the present invention are provided with higher than resisting Middle face is protruding, the setting of this outer rim projection make its roll with needle bearing and when being connected, needle bearing be limited in the intermediate portion in resistance face, this vibrational power flow effectively can avoid shell its central shaft generation axial motion phenomenon relatively of needle bearing, fundamentally solve roller bearing crust offset with tower of exerting oneself and cause accelerated wear test, effectively can not only extend the working life of needle bearing, and can the transmission accuracy of lift cam slicer to a certain extent.
Accompanying drawing explanation
The perspective view of Fig. 1, existing Cam splitter;
The composite structure schematic diagram of Fig. 2, cam of the present invention and needle bearing;
The partial enlargement cross-sectional schematic in A portion in Fig. 3, Fig. 2 of the present invention.
Embodiment
As shown in Figures 2 and 3, a kind of cam 1 of Cam splitter, the side face of cam 1 is distributed with the ribs 11 with driving curve profile, the both sides of ribs 11 have the resistance face 111 offseting and be connected of rolling with needle bearing 21 on tower 2 of exerting oneself, and the both sides in described each resistance face 111 are provided with the outer rim projection 112 higher than middle part.
The present invention arrange in both sides, each resistance face 111 higher than the outer rim projection 112 resisted in the middle part of face 111, resistance face 111 and needle bearing 21 can be made to roll and when being connected, needle bearing 21 to be limited in the intermediate portion in resistance face 111, this vibrational power flow to carry out effective spacing when being in transmission connection with cam 1 to needle bearing 21, can effectively avoid the shell of needle bearing 21 its central shaft 211 relative that axial motion phenomenon occurs, fundamentally solve needle bearing 21 shell offset with tower 2 of exerting oneself and cause accelerated wear test, effectively can not only extend the working life of needle bearing 21, and can the transmission accuracy of lift cam slicer to a certain extent.
The width more than resisting face intermediate portion is greater than needle bearing width 1-2mm, and the preferred height of both sides of the edge projection is 0.1-0.3mm, is so both beneficial to the correction of needle bearing, can plays spacing effect again.
At this, for avoiding arranging of outer rim projection 112 to cause interference to the rolling of needle bearing 21, simultaneously also in order to realize the effectively spacing of the protruding 112 pairs of needle bearings 21 of outer rim, the middle part in described outer rim protruding 112 and resistance face 111 is by arc surface transition.
The above, it is only better embodiment of the present invention, not any pro forma restriction is done to the present invention, every according to know-why of the present invention to any simple modification made for any of the above embodiments, equivalent variations or modification, still belong in the scope of technical solution of the present invention.
