Abstract
The utility model relates to a two-stage harmonic-gear speed-reducing device, which is composed of a motor, a first-stage harmonic drive mechanism, a second-stage harmonic drive mechanism, an input shaft, an output shaft and a machine base. The two-stage harmonic-gear speed-reducing device is characterized in that the cam (11) of the second-stage drive mechanism is supported on the end cover (7) of the machine base (13), and the cam (11) is supported on the end cover (7) of the machine base (13) by a radial adjustable safety clutch for the occasion with the safety clutch. The clutch is composed of a clutch body, a support bearing of the body, a steel ball seat, a steel ball, a guide column, a spring and an adjusting screw. Compared with the existing two-stage harmonic-gear speed-reducing device, the utility model has the advantages of favorable system rigidity, strong overload protection ability, convenient adjustment, installation and use, etc.
Description
The utility model relates to gear drive, a kind of twin-stage harmonic gear reducer.
Advantages such as the twin-stage harmonic gear reducer has simple in structure, and bearing capacity is strong, motion is steady, noise is low, transmission efficiency is high, and velocity ratio is big, volume is little are widely used on the mechanical transmission.But existing twin-stage harmonic gear reducer adopts the kind of drive shown in Figure 1.This kind of drive has two shortcomings: the one, and the cam of second level driving mechanism is bearing on the input shaft, and make input shaft elongated, the transmission system poor rigidity, the 2nd, it obviously is impossible installing adjustable overload clutch between first order transmission and second level transmission additional.Someone also once was placed on clutch before the first order transmission, but can not play overload protective function, also had the people that clutch is placed on after the transmission of the second level, because of moment of torsion can't be realized greatly.
The utility model purpose is to change the kind of drive of twin-stage harmonic gear reducer in the past, realizes two purposes, and the one, strengthen the rigidity of transmission system, the 2nd, make and between the first order and second level transmission, install clutch additional and become possibility.
The utility model twin-stage harmonic gear reducer adopts the kind of drive shown in the accompanying drawing 2, the rigidity ， And that this kind of drive has been strengthened transmission system greatly make install that overload clutch had additional may.
Detailed technology content of the present utility model in conjunction with the embodiments and accompanying drawing further specified.
Fig. 1 is the transmission sketch of prior art twin-stage harmonic gear reducer.
Fig. 2 is the transmission sketch of the utility model twin-stage harmonic gear reducer.
Fig. 3 for embodiment not with the structural representation of the twin-stage harmonic gear reducer of overload clutch.
Fig. 4 is the structural representation of the twin-stage harmonic gear reducer of embodiment's band overload clutch.
Fig. 5 is the structural representation of overload clutch.
The utility model is made up of motor (6), first order harmonic drive mechanism, second level harmonic drive mechanism, input shaft (5), output shaft (1) and support (13), and first order harmonic drive mechanism comprises flexbile gear (2), firm wheel (3), flexible bearing (4), cam (5); Second level harmonic drive mechanism comprises flexbile gear (12), firm wheel (10), flexible bearing (9), cam (11).The cam (11) that it is characterized in that second level driving mechanism is bearing on the end cap (7) of support (13), promptly use end cap (7) supporting second level harmonic generator, this structure solves the problem of the system rigidity deficiency of former twin-stage harmonic speed reducer, as long as parameter is selected rationally, also can exempt the mechanism collapse that other reason causes, make simultaneously and install safety clutch (in case of necessity) additional and become possibility.Fig. 3 has shown not the structure with the twin-stage harmonic gear reducer of safety clutch, the firm wheel (3) of cam (11) the double as first order driving mechanism in the second level driving mechanism in this structure, and promptly both are one.
For installing the safety clutch occasion additional, feature of the present utility model is that cam (11) is bearing on the end cap (7) of support (13) by safety clutch.This clutch is a radially adjustable safety clutch (8), form by clutch body (14), body block bearing (15), steel ball seat (16), block bearing (17), steel ball (18), guide pillar (19), spring (20) and adjustment screw (21), clutch body (14) is connected with the cam (11) of second level harmonic drive mechanism, and the steel ball seat (16) of clutch is connected with the firm wheel (3) of first order harmonic drive mechanism.The first order is just taken turns the connected steel ball seat of moving through of (3) (16), until driving second level cam (11) motion, adjusts screw (21) by steel ball (18) drive clutch body, can adjust the protection moment of safety clutch.Owing to adopt the safety clutch of radial regulation, thereby mechanism size is little, And and because clutch between the I and II harmonic drive mechanism, thereby has the overload protection ability.Adopt sturdy input shaft (5) double as first order cam And among the embodiment and in the no-clutch occasion, the firm wheel of the first order is integrated with second level cam, just taken turns the structure that respectively becomes individual part with second level cam than the input shaft that existing harmonic speed reducer is elongated with the first order, system rigidity is strengthened greatly, and mechanism also simplifies greatly.
The output shaft of present embodiment (1) is the quill shaft of a wounded in the battle keyway or common keyway, this axle is bearing on the retarder body by bearing, this structure is applicable to the input shaft that is sleeved on driven-mechanism, can omit existing retarder connects with driven-mechanism by a coupling, this mode is used, material is saved in installation, ， And easy to adjust.If the output end face of retarder body is processed into the flange plate pattern, can make retarder realize the suspension type installation, can save and take up an area of the space, be applicable to the retarder of using such as traveling-grate stoker.
To do one with the working procedure of the twin-stage harmonic gear reducer of adjustable clutch radially below simply describes: first order harmonic drive mechanism is with rotating speed of motor, by the steel ball seat of adjustable clutch radially, steel ball passes to second level harmonic drive mechanism, second level harmonic drive mechanism passes to output shaft output with moment of rotation, because output sleeve is contained in the input shaft of driven-mechanism, thereby make the driven-mechanism running.When driven-mechanism transships; because clutch body (14) is connected with the cam (11) of second level harmonic drive mechanism; at this moment; the steel ball of clutch (18) can not bear overload power with the contact force of steel ball seat (16); steel ball (18) skids; thereby protected first order harmonic drive mechanism and motor, played the system overload protective action.
Summarize above-mentionedly, the utility model has the following advantages than existing twin-stage harmonic speed reducer, the one, system rigidity is strong, the 2nd, the overload protection ability is strong, the 3rd, adjustment, installation, easy to use, especially be applicable to overload after slip big, the occasion that the clutch frequency is higher.
