Description
Technical field
This utility model relates to a kind of mechanical transmission mechanism, a kind of changeable gearing mechanism of spherical gear of angle of power shaft and output shaft when transmitting power.
Background technology
Existing gear drive is usually used in transmitting the gyration of between centers, and common roller gear transmission power, power shaft must be arranged in parallel with output shaft；Angular wheel can realize the power transmission of power shaft and output any angle of between centers.But above two gear transferring structure, the angle between power shaft and output shaft must be changeless, cannot change the angle between power shaft and output shaft in the course of the work.The gear drive that can change power shaft at any time with the angle of output shaft is it is frequently necessary in industrial robot arm joint and other Universal drive speed adjusting gears.My another Chinese patent 2013205872680 discloses one " pivoted axle gear drive ", and it is variable with the angle of output shaft that it uses the gear of special gear teeth structure to achieve power shaft in power train process, has expanded the application of gear mechanism.But the angle that this pivoted axle gear drive also can only realize power shaft and output shaft changes at grade, it is impossible to realize three-dimensional motion change.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in construction, power shaft can change gearing mechanism of spherical gear with the angle of output shaft, can realize the variable angle of power input shaft and output shaft in three-dimensional space.
This utility model be the technical scheme is that by solving technical problem
Gearing mechanism of spherical gear described in the utility model includes fixing intermeshing parts one and parts two, described parts one and parts two are constituted by tooth engaging piece and mastoid process engaging piece, described tooth engaging piece is the top hemispherical configuration with platform, multiple engaging tooth it is uniformly distributed on the circumference of tooth engaging piece, described mastoid process engaging piece is arranged on the platform on tooth engaging piece top, multiple papillary that one of them mastoid process engaging piece of parts one and parts two is generally evenly distributed on tooth engaging piece tip platform are protruding, another mastoid process engaging piece in parts one and parts two is provided in the column on tooth engaging piece tip platform, the pit that coupling papillary is protruding it is provided with on the end face of described column.
The plurality of papillary protruding one of them be positioned at the center of tooth engaging piece tip platform, other papillary protruding ring is uniformly distributed around center；The bottom surface of described tooth engaging piece is fixedly connected with axostylus axostyle, and described axostylus axostyle is arranged on base by bearing.
Described bearing is self-aligning bearing.
Owing to have employed said structure, this utility model simple in construction, power shaft can change with the angle of output shaft, have wide range of applications, in addition to being favorably improved robot arm work efficiency and optimizing the advantages such as original drive mechanism, apply also for the variable change speed gear box of outbound course improve and simplify the drive mechanism of a lot of engineering goods, improve transmission efficiency, reduce product cost, also can support the use with variator as single Universal drive speed adjusting gear, there is the highest using value and economic benefit.

Detailed description of the invention
As shown in drawings, gearing mechanism of spherical gear described in the utility model includes that fixing intermeshing parts 1 and parts 22, described parts 1 and parts 22 are constituted by tooth engaging piece and mastoid process engaging piece.As shown in Figure 3, Figure 4, described tooth engaging piece is the top hemispherical configuration with platform, multiple engaging tooth it is uniformly distributed on the circumference of tooth engaging piece, described mastoid process engaging piece is arranged on the platform on tooth engaging piece top, multiple papillary projections 3 that one of them mastoid process engaging piece of parts 1 and parts 22 is generally evenly distributed on tooth engaging piece tip platform, another mastoid process engaging piece in parts 1 and parts 22 is provided in the column on tooth engaging piece tip platform, and the end face of described column is provided with the pit 4 of coupling papillary projection 3.
The plurality of papillary protruding 3 one of them be positioned at the center of tooth engaging piece tip platform, other papillary protruding 3 is uniformly distributed around centers, and its top is the most outward-dipping, in order to realize effectively engagement in the biggest angular range；As shown in Figure 1 and Figure 2, the bottom surface of described tooth engaging piece is fixedly connected with axostylus axostyle 5,6, and described axostylus axostyle 5,6 is arranged on base 7,8 by bearing.Described base 7,8 can make parts 1 and parts 22 be maintained in effective engagement range to use various structures form.
As in figure 2 it is shown, described bearing is self-aligning bearing, makes the end face of bearing can be in non-parallel state with the end face of parts 1 and parts 22, and keep running well.It is of course also possible to use cylindrical bearing as shown in Figure 1, the support of a fixed structure is coordinated to realize the end face angle of parts 1 and parts 22 variable.
During use, base 7,8 can arbitrarily swing in effective engagement range and rotate, as shown in Figure 5, parts 1 and parts 22 all can effectively engage, and engage, the when that its end face being parallel to each other when parts 1 are relative with parts 22, papillary protruding 3 embeds in pit 4, it is achieved effectively engage；Angle when between the two becomes larger, and the engagement between parts 1 and parts 22, gradually by engaging each other that mastoid process engagement is converted between engaging tooth, still can realize power transmission.
