Abstract
The utility model relates to a meshing gear component for a harmonic reducing gear, comprising steel wheel concave teeth which are distributed on the inner side of a steel wheel and flexible wheel convex teeth which are distributed on the outer side of a flexible wheel; and the component is characterized in that contact circular arcs are distributed at the openings on the front ends of the steel wheel concave teeth, and the contact circular arcs form a main meshing area. The top ends of the flexible wheel convex teeth are provided with matched circular arcs, and the matched circular arcs form an auxiliary meshing area. When the steel wheel concave teeth and the flexible wheel convex teeth are mutually meshed, at least one surfaces of the main meshing area and the auxiliary meshing area are contacted, and the auxiliary meshing area is not contacted with the bottoms of the steel wheel concave teeth. Consequently, the overall flexible wheel convex teeth are quite short, so that processing and the design of a cutter are facilitated. Meanwhile, the deformation of a flexible wheel can be 40 percents less than that of traditional leading level in the world, so that the improvement of the service life is greatly facilitated. In addition, the existence of transition circular arcs can effectively reduce the risks of breakage and effect losing. Furthermore, after the meshing gear component for the harmonic reducing gear is adopted, the meshing error can be 0 theoretically.
Description
Technical field
The utility model relates to a kind of engaging tooth assembly, relates in particular to a kind of harmonic wave speed reducing machine gear engaging tooth assembly.
Background technique
The profile of tooth of harmonic wave speed reducing machine is a most crucial part in the design, directly has influence on the whole life-span of meshing error, output torque and harmonic wave speed reducing machine.But traditional profile of tooth is the displacement involute, and engagement is few, and output torque is poor, and precision can't guarantee, does not match with the harmonic wave theory of engagement, therefore, has not caught up with the need of work of various use occasions.
The model utility content
The purpose of this utility model is exactly in order to solve the above-mentioned problems in the prior art, and a kind of harmonic wave speed reducing machine gear engaging tooth assembly is provided.
The purpose of this utility model is achieved through the following technical solutions:
Harmonic wave speed reducing machine gear engaging tooth assembly, include steel wheel spill tooth that is distributed in the steel wheel inboard and the flexbile gear convex tooth that is distributed in the flexbile gear outside, wherein: the front opening punishment of described steel wheel spill tooth is furnished with the contact circular arc, and described contact circular arc constitutes main mesh regional; The top of described flexbile gear convex tooth is provided with fit circular arc, and described fit circular arc constitutes secondary mesh regional; When described steel wheel spill tooth and flexbile gear convex tooth were meshing with each other, main mesh regional had at least a face to contact with secondary mesh regional, and secondary mesh regional does not touch with the bottom connection of steel wheel spill tooth.
Above-mentioned harmonic wave speed reducing machine gear engaging tooth assembly, wherein: the degree of depth of described steel wheel spill tooth and flexbile gear convex tooth height ratio are 3: 4.
Further, above-mentioned harmonic wave speed reducing machine gear engaging tooth assembly, wherein: the tooth root of described flexbile gear convex tooth is provided with transition arc, and when steel wheel spill tooth and flexbile gear convex tooth were meshing with each other, main mesh regional did not contact with transition arc.
The advantage of technical solutions of the utility model is mainly reflected in: the whole profile of tooth of flexbile gear convex tooth is shorter, highly be at present external tooth depth about 80%, help processing and the design of cutter.Simultaneously, total number of teeth in engagement of the present utility model is about 30%, and the comparable present world lead level minimizing 40% of deformation of flexible wheel amount, greatly helps the raising in life-span.And, because the existence of transition arc can effectively reduce the risk that fracture failure takes place.Moreover, adopt the utility model after, meshing error can be 0 theoretically, and actually can be controlled at 1 ' and even 30 " in.
Description of drawings
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain.These embodiments use the prominent example of technical solutions of the utility model, and all technological schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the claimed scope of the utility model.In the middle of these accompanying drawings,
Fig. 1 uses steel wheel organigram of the present utility model;
Fig. 2 uses flexbile gear organigram of the present utility model;
Fig. 3 is the organigram of main mesh regional;
Fig. 4 is the organigram of secondary mesh regional;
Fig. 5 is the view that steel wheel spill tooth cooperates with flexbile gear convex tooth forward;
Fig. 6 is steel wheel spill tooth and the reverse view that cooperates of flexbile gear convex tooth.
The implication of each reference character is as follows among the figure:
1 steel wheel spill tooth, 2 flexbile gear convex teeth
3 main mesh regional 4 secondary mesh regionals
Embodiment
Harmonic wave speed reducing machine gear engaging tooth assembly shown in Fig. 1～6, include steel wheel spill tooth 1 that is distributed in the steel wheel inboard and the flexbile gear convex tooth 2 that is distributed in the flexbile gear outside, its unusual part is: the front opening punishment of the steel wheel spill tooth 1 that the utility model adopts is furnished with the contact circular arc, and this contact circular arc constitutes main mesh regional 3.Correspondence is with it, is provided with fit circular arc on the top of flexbile gear convex tooth 2, and this fit circular arc constitutes secondary mesh regional 4.Specifically, when steel wheel spill tooth 1 and flexbile gear convex tooth 2 were meshing with each other, main mesh regional 3 had at least a face to contact with secondary mesh regional 4, and secondary mesh regional 4 does not touch with the bottom connection of steel wheel spill tooth 1.
With regard to the utility model one preferred implementation, consider to obtain bigger mesh volume that the degree of depth of the steel wheel spill tooth 1 that the utility model adopts and flexbile gear convex tooth 2 height ratios are 3: 4.
Further, the tooth root of described flexbile gear convex tooth 2 is provided with transition arc, and when steel wheel spill tooth 1 was meshing with each other with flexbile gear convex tooth 2, main mesh regional 3 did not contact with transition arc.Thus, can form the tooth root of broad, and can directly increase the tooth root radian, reduce the risk that fracture failure takes place by transition arc.
In conjunction with actual use condition of the present utility model, as Fig. 5, with shown in 6.No matter be steel wheel spill tooth 1 and 2 both mutual forwards or reverse cooperations of flexbile gear convex tooth, all have a preferable engagement fit.And, do not need very dark engagement distance just can obtain bigger engagement.In other words, in real-world operation main mesh regional 3 and 4 of secondary mesh regionals need a face mutually separately contact get final product, do not need contact circular arc and the secondary mesh regional 4 affiliated fit circular arc under the main mesh regional 3 to contact fully.
By above-mentioned character express and in conjunction with the accompanying drawings as can be seen, adopt the utility model after, the whole profile of tooth of flexbile gear convex tooth is shorter, length is about 80% of at present external tooth depth, helps processing and the design of cutter.Simultaneously, total number of teeth in engagement of the present utility model is about 30%, and the comparable present world lead level minimizing 40% of deformation of flexible wheel amount, greatly helps the raising in life-span.And, because the existence of transition arc can effectively reduce the risk that fracture failure takes place.Moreover, adopt the utility model after, meshing error can be 0 theoretically, and actually can be controlled at 1 ' and even 30 " in.
