Description
Technical field
The present invention relates to cogwheel gearing field, particularly a kind of gearing of servo turntable.
Background technology
Servo turntable, as a kind of important loading platform, is all widely used with civil area military.Gearing occupies critical role in servo turntable, directly affects the performance of servo turntable.
The servomotor of current servo turntable and reductor are generally fixed on base or revolving dial, and in order to reduce the impact being subject to rugged surroundings, generally be arranged on the inside cavity of sealing, dismounting needs first to remove some external units with when safeguarding, time-consuming longer and workload is larger.And because servomotor can not be separated with revolving dial or base with reductor, the centre distance and the engaged transmission sideshake that make to be arranged on pinion wheel on speed reducer output shaft and swing bearing outer rotor can not adjust, and the transmission accuracy of servo turntable is also wayward.
Summary of the invention
In order to overcome prior art Problems existing, the invention provides a kind of separate type servo turntable gearing of adjustable backlash, this gearing is convenient to safeguard, transmission accuracy is easy to control, and structure is reliable.
A separate type servo turntable gearing for adjustable backlash, comprises base, revolving dial, erecting frame, servomotor, gearing, and gearing comprises the swing bearing of pinion wheel, reductor and band external tooth.Base upper bottom surface is fixed in the outer ring of swing bearing; Revolving dial upper end is provided with loading platform, and bottom surface is provided with groove, is provided with window between groove and outer wall; Revolving dial to cover on swing bearing and is connected with swing bearing inner ring; Erecting frame is connected with revolving dial by hinge axis, and its inside is provided with reductor, pinion wheel and servomotor; Reductor is connected with servomotor; Pinion wheel is located on the output shaft of reductor, and pinion wheel engages in window place with the external tooth of swing bearing.
Revolving dial is provided with pad in the sidewall of window surrounding, adjusts the quantity of pad thus the distance between adjustment erecting frame and revolving dial, and then the centre distance of adjustment swing bearing outer rotor and pinion wheel.
The present invention compared with prior art, have the following advantages: during (1) service equipment, erecting frame can around hinge axis, and drive pinion wheel to be separated with swing bearing outer rotor, under servomotor power-off is in band-type brake state, servo turntable have gentle hands can be enable easily to promote; (2) after erecting frame rotation, servomotor, reductor and pinion wheel expose, and are easy to carry out dismounting and maintenance to it; (3) be furnished with pad between erecting frame and revolving dial faying face, drive centre distancc and the gears meshing sideshake of pinion wheel and swing bearing outer rotor can be adjusted by increase and decrease pad quantity, improve transmission accuracy.
Below in conjunction with Figure of description, the present invention is described further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the partial sectional view of gearing of the present invention;
Fig. 3 is the structural representation of the present invention under released state.
Embodiment
Composition graphs 1, a kind of separate type servo turntable gearing of adjustable backlash, comprises base 1, revolving dial 2, erecting frame 3.
Composition graphs 2, device also comprises gearing, and gearing comprises pinion wheel 5, reductor 6 and the swing bearing 4 being with external tooth.
Revolving dial 2 upper end is provided with loading platform 2-2, loading platform 2-2 is connected with revolving dial 2 sidewall by reinforcement, revolving dial 2 bottom surface is provided with groove, is provided with window 2-1 between the outer wall of groove and revolving dial 2, and revolving dial 2 bottom surface and base 1 upper bottom surface are connected by screw.Swing bearing 4 is positioned at the groove of revolving dial 2, and its outer ring is connected with base 1 upper bottom surface by screw, and inner ring is connected with revolving dial 2 by screw, and revolving dial 2 can by relatively rotating between swing bearing 4 and base 1.
Erecting frame 3 is arranged at revolving dial 2 side, is connected with revolving dial 2 by hinge axis 9, is fastenedly connected under servo turntable duty by screw and revolving dial 2, erecting frame 3 and revolving dial 2 can be considered as one.Its inside is provided with reductor 6, pinion wheel 5 and servomotor 7; Reductor 6 is connected with servomotor 7; Pinion wheel 5 is located on the output shaft of reductor 6, and pinion wheel 5 engages in window 2-1 place with the external tooth of swing bearing 4.Servomotor 7 passes through reductor 6 driving pinion 5 around the rotation of reductor 6 output shaft, pinion wheel 5 engages with the outer rotor of swing bearing 4 simultaneously, because the outer ring of swing bearing 4 is fixed, meshed transmission gear can make pinion wheel 5 around the revolution of swing bearing 4 center, drives erecting frame 3 and revolving dial 2 around swing bearing 4 center rotating.
Revolving dial 2 is provided with pad 8 in the sidewall of window 2-1 surrounding, adjusts the quantity of pad 8 thus the distance between adjustment erecting frame 3 and revolving dial 2, and then the centre distance of adjustment swing bearing 4 outer rotor and pinion wheel 5.
When servo turntable needs to safeguard, unclamp the trip bolt of erecting frame 3, pull erecting frame 3 to rotate around hinge axis 9, erecting frame 3 is separated with revolving dial 2, servomotor 7, reductor 6 are in pinion wheel 5 etc. the state of exposing, and conveniently can overhaul it, safeguard and change.By the quantity of pad 8 between adjustment erecting frame 3 and revolving dial 2, the distance between erecting frame 3 and revolving dial 2 can be adjusted, namely the centre distance of swing bearing 4 outer rotor and pinion wheel 5 is adjusted, the change of centre distance can change the sideshake of gears meshing, and meshing backlass directly affects gear-driven precision.Adjust pad 8 quantity by several times, meshing backlass can be made to reach optimum, and transmission accuracy reaches requirement.
