Description
Technical field
The utility model relates to a kind of speed reducer, relates in particular to a kind of RH harmonic reduction machine.
Background technique
Speed reducer generally is used for the transmission device of low rotation speed large torque; Motor. the power that internal-combustion engine or other run up reaches the purpose of deceleration through the gearwheel on the few gear engagement output shaft of the number of teeth on the input shaft of speed reducer; Common speed reducer also has and several the same principle gear is reached desirable deceleration effect; The ratio of the number of teeth of big small gear is exactly a velocity ratio.
Its motion principle all is that the small column in interior wheel chamber moves in a circle, and the poor tooth engagement of external gear makes it motion, thereby carries out being meshing with each other of tooth and tooth with foreign steamer in can realizing.Because small column revolution one whole circle, corresponding point just reaches an extreme value, promptly walks a tooth, thereby reaches the effect of deceleration.
The model utility content
The purpose of the utility model is exactly the problems referred to above that exist in the existing technology in order to solve, and a kind of RH harmonic reduction machine is provided.
The purpose of the utility model realizes through following technological scheme:
RH harmonic reduction machine; Include central axis component; Wherein: the peripheral working surface of said central axis component is arranged with the internal gear assembly through the main bearing assembly; The peripheral working surface of described internal gear assembly is arranged with external gear, and the front end of said central axis component is connected with integrated type criss-crossing bearing, and the tail end of said central axis component is connected with the auxiliary bearing assembly.
Further, above-mentioned RH harmonic reduction machine, wherein: described main bearing assembly is a deep groove ball bearing.
Further, above-mentioned RH harmonic reduction machine, wherein: described internal gear assembly is by having at least two identical internal gears to rearrange side by side.
Further, above-mentioned RH harmonic reduction machine, wherein: described auxiliary bearing assembly is a four-point contact ball.
Further, above-mentioned RH harmonic reduction machine, wherein: described central axis component tail end is provided with keyway.
Further, above-mentioned RH harmonic reduction machine, wherein: be provided with the quill shaft passage in the described central axis component.
Again further, above-mentioned RH harmonic reduction machine, wherein: the inwall of described quill shaft passage is provided with the linking screw thread.
The advantage of the utility model technological scheme is mainly reflected in: through the existence of quill shaft passage, and machining accuracy is guaranteed, and makes the more compact structure of whole part, and precision is higher.Simultaneously, considered client end, not only convenient and practical, can also on this basis, optimize whole structure, make compact more with accurately, export more stablely, speed reducer work is more steady.

Embodiment
The RH harmonic reduction machine shown in Figure 2 like Fig. 1 includes central axis component 1, and its unusual part is: the peripheral working surface of the central axis component 1 that the utility model adopted is arranged with internal gear assembly 2 through the main bearing assembly.Simultaneously, consider carrying out smoothly of slow down transmitting, be arranged with external gear 3 at the peripheral working surface of internal gear assembly 2.And the front end of central axis component 1 is connected with integrated type criss-crossing bearing 4, makes that the structure of speed reducer is compact more, and rigidity strengthens.Corresponding with it is, is connected with the auxiliary bearing assembly at the tail end of central axis component 1.
With regard to the utility model one preferred implementation, consider to let the rotation of main bearing assembly more smooth and easy that play the effect of dual-support structure, the main bearing assembly of employing is a deep groove ball bearing 5.Like this, the integrally-built couple that makes speed reducer is balance more, and intensity is higher, exports more stablely, and speed reducer work is more steady.
Further, accurately whenever walk a tooth, thereby reach the effect of deceleration in order to realize the smooth and easy of moderating process, the internal gear assembly 2 of employing is by having at least two identical internal gears to rearrange side by side.
Simultaneously, consider and need bear radial load and thrust load simultaneously, also can bear pure thrust load, can under high rotational speed, work, the auxiliary bearing assembly that the utility model adopted is a four-point contact ball 6.
Again further, considered the connection of client end, central axis component 1 tail end is provided with keyway 7.Simultaneously, pass in the centre, be provided with quill shaft passage 8 in the central axis component 1 for making things convenient for client's cable etc.And the inwall of quill shaft passage 8 is provided with the linking screw thread, is convenient to the installation of other assemblies.Like this, can satisfy under equal specification employed space and raw material more saves.
Can find out through above-mentioned character express, adopt the utility model after, through the existence of quill shaft passage, and machining accuracy is guaranteed, and makes the more compact structure of whole part, precision is higher.Simultaneously, considered client end, not only convenient and practical, can also on this basis, optimize whole structure, make compact more with accurately, export more stablely, speed reducer work is more steady.
