Abstract
The invention discloses a self-aligning roller bearing inner ring convenient for roller installation. The self-aligning roller bearing inner ring comprises an inner ring body, wherein a flange is formed at two sides of the inner ring body; a first rail and a second rail are arranged in the middle of the inner wall of the inner ring body and both have inclined angles with the vertical axis of a bearing; the first rail and the second rail are symmetrically arranged in a splay manner; a middle retainer support platform is arranged between the first and second rails; the upper surface of the flange forms an upwards inclined angle with the horizontal axis of the bearing; and the flange is low in outside and high in inside. According to the self-aligning roller bearing inner ring convenient for roller installation, the upper surface of the flange of the bearing inner ring is arranged in an inclined manner, so that when being installed, a roller is not in contact with an inner wall, the possibility of damaging the inner ring by the roller is avoided, the bearing is protected and the service life of the bearing is prolonged.
Description
Technical field
The invention belongs to bearing manufacturing technology field, be specifically related to a kind of selfaligning roller bearing inner ring of being convenient to install roller.
Background technique
In Production of bearing enterprise, while assembling the roller of selfaligning roller bearing, as shown in Figure 2, because the rib face of bearing inner race is plane, while packing roller into, roller can move inward along the angle of inwall with the inwall of bearing inner race roller after point of contact contacts, if when assembler fills roller, firmly excessive, will form damage at point of contact, the flexibility and the precision that affect bearing rotary shorten bearing life thereupon.
Summary of the invention
For addressing the above problem, the invention discloses a kind of selfaligning roller bearing inner ring of being convenient to install roller, stop the possibility of roller damage bearing inner race, protection bearing, the working life of prolongation bearing.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of selfaligning roller bearing inner ring of being convenient to install roller, it is characterized in that: comprise inner ring body, described inner ring body both sides are provided with rib, in the middle of inner ring inner body wall, be provided with the first track and the second track that there are angle of inclination with bearing vertical axis, described the first track and the second track are splayed configuration and are symmetrical arranged, in the middle of the first track and the second track, be provided with guide ring support platform, on described rib, plane and bearing horizontal axis have angle of inclination upwards, and on rib, plane is outer low and inner high.
As a modification of the present invention, on described rib, the angle of inclination of plane and bearing horizontal axis is 9 ° 20 '-15 °.
As a modification of the present invention, on described rib the angle of inclination of plane and bearing horizontal axis be 9 ° 20 '.
As a modification of the present invention, the angle of inclination of described the first track and the second track and bearing vertical axis be 9 ° 20 '.
As a modification of the present invention, described the first track and the second raceway surface are inner concave shape.
As a modification of the present invention, described rib height is lower than guide ring support platform height.
As a modification of the present invention, on described rib, plane surface is inner concave shape.
As a modification of the present invention, described inner ring body adopts GCr15 steel.
The invention has the beneficial effects as follows:
A kind of selfaligning roller bearing inner ring of being convenient to install roller of the present invention; plane layout on bearing inner race rib is had to angle of inclination, make roller not contact when mounted inwall, stop the possibility of roller damage bearing inner race; protection bearing, the working life of prolongation bearing.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is original working state figure.
Reference numerals list:
1, inner ring body, 2, rib, 3, the first track, 4, the second track, 5, guide ring support platform.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand following embodiment and only be not used in and limit the scope of the invention for the present invention is described.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometrical center.
As shown in the figure, a kind of selfaligning roller bearing inner ring of being convenient to install roller of the present invention, comprise inner ring body 1, described inner ring body 1 both sides are provided with rib 2, in the middle of inner ring body 1 inwall, be provided with the first track 3 and the second track 4 that there are angle of inclination with bearing vertical axis, described the first track 3 and the second track 4 are splayed configuration and are symmetrical arranged, in the middle of the first track 3 and the second track 4, be provided with guide ring support platform 5, on described rib 2, plane and bearing horizontal axis have angle of inclination upwards, and on rib 2, plane is outer low and inner high.
When work, because plane layout on bearing inner race rib has angle of inclination upwards, make roller not contact when mounted inwall, stop the possibility of roller damage bearing inner race, protection bearing, the working life of prolongation bearing.
The first track 3 of the present invention and the second track 4 and the inclination angle beta of bearing vertical axis be 9 ° 20 ', in order to make roller not contact when mounted the first track 3 and the second track 4, the tilt angle alpha of plane and bearing horizontal axis on described rib 2 is made as 9 ° 20 '-15 ° by the present invention, α angle is not less than β, make rib 2 attenuation for preventing that α angle is excessive, the hidden danger that roller can fly out in the course of the work, on described rib 2 angle of inclination of plane and bearing horizontal axis be 9 ° 20 ', plane and unidirectional parallel track on rib 2, when installation, do not encounter track, described inner ring body 1 adopts GCr15 steel simultaneously, hardness is high, wear-resisting.
The roller that selfaligning roller bearing fills is cydariform, the little belly broad in the middle in two, can live freely for after roller is installed, described the first track 3 and the second track 4 surfaces are inner concave shape, size can be held the pregnant of roller, in like manner, when being installed, reduces on roller the intermediate portion of encountering roller, plane surface on described rib 2 is to inner concave shape, reduce and scratch, improve bearing quality, in order to make assembling easily, described rib 2 height are lower than guide ring support platform height 1-2mm, easier injection when roller assembling.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned mode of execution, also comprises the technological scheme being made up of above technical characteristics combination in any.
