Technical field
The utility model relates to spline manufacturing technology field, refers in particular to a kind of modified model spline pair.
Background technique
In machining manufacturing and assembling industry, splined is a kind of use connecting mode very widely, and splined generally is made up of internal spline and external splines.Inside and outside spline is multiple tooth part, and the spline on inner periphery is an internal spline, and the spline on outer cylinder surface is an external splines.Obviously, splined is that flat key is connected in the development on the number.
Because structural type and manufacturing process is different, connect with flat key relatively, splined is having following characteristics aspect intensity, technology and the use: because directly and equably making more tooth and groove on the axle with on the hub bore, so connect stressed comparatively even; Because of groove is more shallow, tooth root place stress is concentrated less, and axle is less with the strength reduction of hub; The number of teeth is more, and total area of contact is bigger, thereby can bear bigger load; Parts on shaft is good to neutrality with axle, 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, to neutral high.Therefore, splined is usually used in centering precision requirement height, transmitting torque is big or the joint part of frequent slippage.
And it is well-known, the manufacturing process of spline is compared the flat key connection and will be responsible for much especially needing to process the splined shaft of external splines, needs special profile cutter, gear machining apparatus by specialties such as the gear shaping machine of specialty or gear hobbing machines just can process, and processing cost is very high.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of cutting down finished cost greatly and the modified model spline pair of manufacture difficulty.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of modified model spline pair, comprise splined shaft, and the outer wall of described splined shaft offers at least three flat-bottom slots, and at least three flat-bottom slot annulars are distributed in the outer wall of splined shaft; The two side of described flat-bottom slot is all vertical mutually with the bottom surface of flat-bottom slot; The two side of described flat-bottom slot is parallel to each other.
Wherein, the quantity of described flat-bottom slot is six, and six flat-bottom slot annulars are distributed in the outer wall of splined shaft.
Wherein, also comprise spline housing, the inwall of this spline housing is provided with the embedding key of at least three projectioies, and at least three embedding key annulars are distributed in the inwall of spline housing; The cross-sectional sizes of embedding key matches with the cross-sectional sizes of flat-bottom slot; When spline housing and described splined shaft socket, an embedding key is embedded in the flat-bottom slot.
Wherein, the number of the quantity of described embedding key and described flat-bottom slot is six; When spline housing and described splined shaft socket, six embedding keys are embedded at respectively in six flat-bottom slots.
Wherein, the number of the quantity of described embedding key and described flat-bottom slot is 12; When described spline housing and described splined shaft socket, 12 embedding keys are embedded at respectively in 12 flat-bottom slots.
The beneficial effects of the utility model are: the utility model provides a kind of embodiment one of modified model spline pair, comprises splined shaft, and the outer wall of splined shaft offers at least three flat-bottom slots, and at least three flat-bottom slot annulars are distributed in the outer wall of splined shaft; The bottom surface of the equal flat-bottom slot in two side of described flat-bottom slot is vertical mutually; The two side of described flat-bottom slot is parallel to each other.The splined shaft that adopts the technical program is in the manufacturing of spline, need not special profile cutter, also need not gear machining apparatus, with conventional complex milling machine tool or be with C axle machining center can carry out the manufacturing of flat-bottom slot by specialties such as the gear shaping machine of specialty or gear hobbing machines; Be applicable to numerically controlled automatic production, machining accuracy improves greatly, can realize interworking; And the distance of spline back-up ring one processing, by original wide half of keyway that shorten to more than 30 millimeters, can arrive 0.5 millimeter recently, its difficulty of processing is identical with the difficulty of processing of flat key groove, thereby greatly reduce the difficulty of processing of described modified model spline pair, reduced the generation manufacture cost of spline, the economic benefit height; The use principle of this modified model spline pair is the same with traditional spline pair with transmission efficiency, and applicability height, practical is easy to apply.
