Description
Technical field
The utility model relates to a kind of components of constant velocity cardan joint, more specifically to a kind of clamping steel ball, guidance
The eccentric cage retainer of two Shaft angles.
Background technique
Cage also known as constant velocity cardan joint are a very important components in car drive system, and effect is will to send out
The power of motivation is transmitted to driving wheel from speed changer, and driving car is run at high speed, therefore cage is a kind of carefully component,
Retainer is a components in cage, and traditional retainer is concentric retainer, the disadvantage is that: it can only be around some revolution, no
Axial stretching and the requirement that driving-shaft assembly axial distance changes at any time can be can not meet.
Summary of the invention
In order to overcome the shortcomings of background technique, the purpose of this utility model is to provide a kind of energy axial stretchings simultaneously can be full
Sufficient driving-shaft assembly axial distance changes the eccentric cage retainer of requirement at any time.
The technical scheme adopted by the utility model is a kind of bias cage retainer, includes retainer ontology, the guarantor
It holds frame ontology and forms outer peripheral surface and inner peripheral surface to be cyclic annular, retainer, which is equipped with, is arranged along retainer etc. point and is connected outer peripheral surface and interior
The arc-shaped window of circumferential surface, the both ends of the retainer are respectively left end and right end, and the inner peripheral surface of the retainer is divided into direction
The spherical outside surface of left end and Internal Spherical Surface towards right end, the distance and Internal Spherical Surface of the sphere centre to retainer widthwise central
Central point is equidistant to retainer widthwise central, and retainer center is respectively facing both ends and shrinks in gradual change type, described
Spherical outside surface be equipped with a seam allowance, the axial diameter of the seam allowance is spherical outside surface midpoint to widthwise central and Internal Spherical Surface midpoint
To 2 times of widthwise central.
Preferably, 15 are formed between the outer peripheral surface intermediate point of the retainer and the axis of retainer outer peripheral surface central point
The angle of degree.
Preferably, the seam allowance forms step on spherical outside surface, and the seam allowance is cylindrical.
Preferably, limited step is respectively equipped on the bottom wall of the arc-shaped window and roof both ends.
Preferably, the sidewall direction of the limited step towards arc-shaped fenestra is formed slopely inclined-plane.
Preferably, the sphere centre is to the distance and Internal Spherical Surface central point of retainer widthwise central to retainer
The distance of widthwise central is 24mm-24.75mm.
Preferably, the axial diameter of the seam allowance is 49mm-49.5mm.
Preferably, the diameter at the Internal Spherical Surface and spherical outside surface both ends is respectively 44.5mm.
The beneficial effects of the utility model are: due to the retainer central point towards left side and right side be in gradual change type
Gradually become, therefore, retainer forms bias when in cage with transmission axis connection, and in rotation, energy axial stretching, is able to satisfy
The requirement that driving-shaft assembly axial distance changes at any time.And seam allowance, the seam allowance internal diameter are provided at the spherical outside surface of retainer
Slightly larger than the retainer spherical outside surface diameter, to realize smoothly assembly.
The utility model embodiment is described further with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model embodiment；
Fig. 2 is the cross-sectional view of the utility model embodiment.
Specific embodiment
If Fig. 1-Fig. 2 shows, it includes retainer ontology 1, the holding that the utility model, which provides a kind of eccentric cage retainer,
Frame ontology 1 is cyclic annular formation outer peripheral surface 11 and inner peripheral surface 12, and retainer, which is equipped with, to be arranged along retainer etc. point and outer peripheral surface is connected
And the arc-shaped window 13 of inner peripheral surface, the both ends of the retainer 1 are respectively left end and right end, the inner peripheral surface 12 of the retainer
It is divided into the spherical outside surface 2 towards left end and the Internal Spherical Surface 3 towards right end, 2 central point of the spherical outside surface is to retainer widthwise central a's
Distance and 2 central point of Internal Spherical Surface being equidistant to retainer widthwise central a, retainer center are respectively facing both ends in gradually
Variant is shunk, and the spherical outside surface 2 is equipped with a seam allowance 4, and the axial diameter of the seam allowance 4 is 2 midpoint of spherical outside surface to width
Degree center a and 3 midpoint of Internal Spherical Surface are to 2 times of widthwise central a.In above scheme, since the central point of the retainer is towards left end
Face and right side are gradually tapered up in gradual change type, the diameter phase of the diameter and central point at Internal Spherical Surface 3 of the center of spherical outside surface 2
Together, it is then gradually shunk towards both sides, that is to say, that the diameter at Internal Spherical Surface both ends is less than intermediate diameter, and therefore, retainer is in ball
Bias is formed when on cage with transmission axis connection, forms centering type retainer, energy axial stretching, it is total to be able to satisfy transmission shaft in rotation
The requirement changed at any time at axial distance, and seam allowance 4 is provided at the spherical outside surface of retainer, which is slightly larger than
The retainer spherical outside surface diameter, to realize smoothly assembly.
15 degree are formed between the axis of the 1 outer peripheral surface central point of 11 intermediate point of outer peripheral surface and retainer of the retainer 1
Angle.In view of the thick variation that effectively keeps away of nonconcentric cage relatively delays, therefore, retainer outer peripheral surface central point and retainer periphery
The tangent circular conical surface formed into 15 ° of angles of the axis of face central point, it is ensured that the requirement of intensity can make retainer in rotary course
In be able to achieve 30 ° of pivot angle.
The seam allowance 4 forms step on spherical outside surface, and the seam allowance is cylindrical.The setting of seam allowance, convenient for keeping
Assembly between frame and the other components of cage.
Limited step 5 is respectively equipped on the bottom wall of the arc-shaped window 13 and roof both ends.Window is for installing steel
Ball, during rotation, limited step 5 forms limit to steel ball, and steel ball can be prevented towards both sides over-tilting.
The sidewall direction of limited step 5 towards the arc-shaped fenestra is formed slopely inclined-plane.Inclined-plane has a buffering
The gradient, reduce steel ball and retainer abrasion.
2 central point of spherical outside surface to retainer widthwise central a distance and 3 central point of Internal Spherical Surface to retainer width
The distance of center a is 24mm-24.75mm.The axial diameter of the seam allowance 4 is 49mm-49.5mm.From the above, it can be seen that
The diameter of seam allowance a just 2 central point of spherical outside surface is to retainer widthwise central a and 3 central point of Internal Spherical Surface to retainer widthwise central a
2 times of distance, which is just exactly eccentricity, in this way, making retainer while being easy assembly, guarantees its structure
Compactedness.
The diameter at 2 both ends of Internal Spherical Surface 3 and spherical outside surface is respectively 44.5mm.
The width of seam allowance 4 is 7.5mm.
Every technical staff's notice: although the utility model is described according to above-mentioned specific embodiment, this
The invention thought of utility model is not limited to that the utility model, and any repacking with the utility model thought will all be received
Enter in this patent scope of patent protection.
