Description
Technical field
The utility model relates to mechanical transmission fields, and in particular to a kind of lightweight harmonic speed reducer.
Background technique
There are mainly two types of the speed reducers for being applied to robot field at present, and one is Japanese Nabtesco Di Renjing machine companies
Rotate Vector retarder (abbreviation RV retarder), another kind is the harmonic speed reducer of Japanese Harmonic Drive, he
Almost monopolized the whole world robot retarder.In joint of robot, due to RV retarder have higher rigidity and
RV retarder is generally placed on the heavy duty position such as base, large arm, shoulder by rotating accuracy, and harmonic speed reducer is placed
In forearm, wrist or hand.
The transmission of harmonic speed reducer is to realize that transformation of speed and power pass by the elastomeric radial of thin wall flexible gear
It passs, thin wall flexible gear capacity and transmission stiffness are relatively low, while flexible gear also easily occurs because of cyclic deformation
Fatigue damage, therefore the precision transmission system in being mainly used for, gently loaded, multi-purpose work industry robot wrist, the precision of hand subtract
Speed transmission.
However for being adopted in existing harmonic speed reducer frequently with firm gear and the integrated molding of flexbile gear set or firm gear and flexbile gear set
It is fixed with split type structure and by screw, integrated molding firm gear construction weight is larger and noise is extremely ear-piercing, split type knot
Structure is time-consuming during the installation process due to needing screw to be fixed, and the high-temperature vibrating ring in long-term operation process
Border, which easily loosens screw, causes retarder precision to change or even damage.For this reason, it is necessary to existing harmonic speed reducer
Structure advanced optimize, reduce noise and weight to realize, with easy to install and use.
Summary of the invention
It is small the purpose of the utility model is to overcome a kind of noise in place of the deficiencies in the prior art, is provided, it is light-weight and
Lightweight harmonic speed reducer easy for installation.
The purpose of this utility model is achieved through the following technical solutions:
A kind of lightweight harmonic speed reducer, including flexbile gear set, firm gear, flexbile gear, wave producer and flexible bearing, the flexbile gear
Each central axis is on one wire when assembling for set, firm gear, flexbile gear and wave producer；It is formed in the flexbile gear set for installing firm gear
Annular groove, annular groove upper inside wall is formed with internal thread, is also uniformly formed with multiple bottom surface pin holes on the boss of annular groove bottom surface；The firm gear outer wall
On be formed with outer silk compatible with the internal thread of annular groove inner wall, multiple firm gears compatible with bottom surface pin hole position are formed with inside firm gear
Longitudinal pin hole.
Moreover, being also compounded between the annular groove internal thread and bottom surface boss using noise reduction buffer layer made of rubber material.
Moreover, being also formed with multiple lateral pin holes being connected with longitudinal pin hole, the annular groove inner wall on the firm gear side wall
On be also formed with multiple mounting grooves compatible with lateral pin hole.
Moreover, also embedded with lateral pin in the transverse direction pin hole, and it is half that the pin, which is located at longitudinal one side end of pin hole,
It is spherical.
The preferred embodiment of the utility model is that the noise reduction buffer layer and lateral pin hole connection are formed with mounting hole.
The advantages of the utility model and economic effect are:
1, the utility model overcomes the technical problem that the assembly of conventional harmonic retarder is taken a lot of work, firm gear fixation is unstable, passes through
Using it is horizontal, indulge the lateral pin that two-way pin hole cooperation is formed with hemispherical plunger, will be horizontal when can be embedded in longitudinal pin when fixed
It is headed into mounting groove simultaneously to pin, achievees the effect that lateral, longitudinal while fixing, substantially reduce assembly period, simplify
Assembly technology, while improving the fixed effect of firm gear.
2, the utility model is by using the buffer layer being formed below annular groove internal thread in advance, the buffering when firm gear is screwed into annular groove
Layer achievees the effect that noise reduction, damping with firm gear interference fit.

Fig. 2 is the structural schematic diagram of the utility model firm gear；
Fig. 3 is the structural schematic diagram of the utility model flexbile gear set；
Fig. 4 is the structural schematic diagram (showing lateral pin) of the utility model firm gear.
Specific embodiment
For the contents, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates attached drawing
Detailed description are as follows.It should be noted that the present embodiment be it is descriptive, be not restrictive, cannot thus limit practical
Novel protection scope.
A kind of lightweight harmonic speed reducer, including flexbile gear set 2, firm gear 1, flexbile gear, wave producer and flexible bearing, it is described soft
Each central axis is on one wire when assembling for wheel case, firm gear, flexbile gear and wave producer；It is formed in the flexbile gear set for installing just
The annular groove of wheel, annular groove upper inside wall are formed with internal thread 9, are also uniformly formed with multiple bottom surface pin holes 7 on the boss of annular groove bottom surface；The firm gear
It is formed with outer silk 3 compatible with the internal thread of annular groove inner wall on outer wall, is formed with and multiple is adapted with bottom surface pin hole position inside firm gear
