By installing the fixing ring and utilizing the clip combination of the fixing ring and other parts, the whole structure of the spline is free from damage, and the spline can satisfy the stress requirements in the working process, thus the service life of the spline is prolonged.
Description
Technical field
The utility model relates to spline housing, especially relates to the spline housing for stationary mechanism part, belongs to mechanical connecting element.
Background technique
Splined is comprised of internal spline and external splines.Inside and outside spline is multiple tooth part, and the spline on inner periphery is internal spline, and the spline on outer cylinder surface is external splines.Obviously, splined is that flat key is connected in the development on number.
The effect of splined shaft: be that mechanical transmission is a kind of, the same with flat key, woodruff key, taper key effect, be all to transmit mechanical torque, the structure of splined shaft: the appearance at axle has keyway longitudinally, the revolving part that is enclosed within on axle also has corresponding keyway, can keep with the axle synchronous rotary.In rotation, what have can also do longitudinal sliding motion on axle, as the gearbox gear-shift gear etc.
Due to the difference of structural type and manufacturing process, connect with flat key relatively, splined has following characteristics in intensity, technique and use: because directly and equably making more tooth and groove on axle with on hub bore, therefore connect stressed comparatively even; Because groove is more shallow, tooth root place stress is concentrated less, and the strength reduction of axle and hub is less; The number of teeth is more, and total area of contact is larger, thereby can bear larger load; The centering of parts on shaft and axle is good, and this is very important to high speed and precision machinery; Guidance quality is good, and this is very important to moving connection; The method of available grinding improves machining accuracy and connects quality; Manufacturing process is more complicated, sometimes needs Special Equipment, and cost is higher.Applicable situation: the centering precision requirement is high, transmitting torque is large or the connection of frequent slippage.
Traditional spline is only to be connected with splined shaft, but spline self can't be connected with miscellaneous part, normally adopts the mode of offering tapped hole on spline to connect, and the mode of this perforate has been destroyed the intensity of spline itself, cause the understrressing of spline when work, shorten working life.
The model utility content
When being to overcome existing spline joint, the purpose of this utility model need to destroy the shortcoming of spline structure, a kind of spline housing for stationary mechanism part is provided, this spline housing is by arranging retaining ring, utilize retaining ring to be combined with the buckle of miscellaneous part, make the overall structure of spline not be damaged, spline can satisfy the stress requirement when work, make extend the working life of spline.
The purpose of this utility model is achieved through the following technical solutions: the spline housing that is used for stationary mechanism part, comprise that inside is provided with the cylinder of penetration hole, and the axis of penetration hole and the dead in line of cylinder, the outer wall of described penetration hole protrudes and forms groove, and the two ends of groove are communicated with the two ends of cylinder simultaneously, a wherein end of described cylinder is provided with retaining ring, this end face of cylinder and one of them end face of retaining ring are in same plane, and cylinder is arranged on retaining ring inside and contacts with the inwall of retaining ring.
Further, described retaining ring comprises retaining ring one, retaining ring two and retaining ring three, wherein the inwall of retaining ring one contacts with the wall of cylinder, retaining ring two is arranged on the outside of retaining ring one, retaining ring three is arranged on the outside of retaining ring two, the inwall of retaining ring three contacts with the outer wall of retaining ring two, and the inwall of retaining ring two contacts with the outer wall of retaining ring one, and the end face of the bottom of the bottom of retaining ring one, retaining ring two and the bottom of retaining ring three and cylinder is in same plane.
Further, described column body arranges helix, and helix is arranged on the position between adjacent notches in groove.
Further, the width of described groove is 11mm to 13mm.
Further, the width of described groove is 12mm.
In sum, the beneficial effect of model utility is: this spline housing utilizes retaining ring to be combined with the buckle of miscellaneous part by retaining ring is set, and makes the overall structure of spline not be damaged, spline can satisfy the stress requirement when work, make extend the working life of spline.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Mark and corresponding component title in accompanying drawing: 1-groove; 2-helix; 3-penetration hole; 4-cylinder; 5-retaining ring one; 6-retaining ring two; 7-retaining ring three.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but mode of execution of the present utility model is not limited only to this.
Embodiment:
As shown in Figure 1, the spline housing that is used for stationary mechanism part, comprise that inside is provided with the cylinder 4 of penetration hole 3, and the dead in line of the axis of penetration hole 3 and cylinder 4, the outer wall of described penetration hole 3 protrudes and forms groove 1, and the two ends of groove 1 are communicated with the two ends of cylinder 4 simultaneously, and a wherein end of described cylinder 4 is provided with retaining ring, this end face of cylinder 4 and one of them end face of retaining ring are in same plane, and cylinder 4 is arranged on retaining ring inside and contacts with the inwall of retaining ring.Cylinder 4 is spline after penetration hole 3 is set, and becomes spline housing after retaining ring is set, and the retaining ring on spline housing can be fixed together spline and other parts, has avoided carrying out perforate on cylinder.
Described retaining ring comprises retaining ring 1, retaining ring 26 and retaining ring 37, wherein the inwall of retaining ring 1 contacts with the wall of cylinder 4, retaining ring 26 is arranged on the outside of retaining ring 1, retaining ring 37 is arranged on the outside of retaining ring 26, the inwall of retaining ring 37 contacts with the outer wall of retaining ring 26, the inwall of retaining ring 26 contacts with the outer wall of retaining ring 1, and the end face of the bottom of the bottom of retaining ring 1, retaining ring 26 and the bottom of retaining ring 37 and cylinder 4 is in same plane.By the retaining ring of multilayer is set, can realize that retaining ring is combined with the tight buckle of miscellaneous part, the diameter of retaining ring 37 is maximum, between retaining rings at different levels, adopt the mode of welding to be connected between retaining ring 1 and cylinder 4, increases the fastness in fixing.
