Description
Technical field
The invention belongs to governor regulation technology fields, are related to a kind of rotation device for precisely regulating.
Background technology
Governor rotational speed regulation is usually to rotate speed adjusting lever or rotate droop adjustment screw using common wrench to realize at present,
It is time-consuming and laborious when being adjusted and inaccurate, add many difficulties to the working service in outfield.With governor technology
Development, governor flight-line service is simple and convenient to wait requirements that governor structure is caused to tend to simplify, this device can make governor
Requiring the characteristics of accurate quick in terms of outer field control.
The content of the invention
The purpose of the present invention：It is proposed that one kind is simple in structure, it is easy to operate, it can ensure the accurate rotational speed regulation work(of governor
Energy.
Technical scheme：A kind of rotation device for precisely regulating, which is characterized in that including housing, adjusting nut 1,
Adjust worm screw 2, adjustment gear 3, lock-screw 4 and adjustment screw 5；Adjusting nut 1 is locked by being threadably mounted at case top
Screw 4 is tightened in the external arc of adjusting nut 1 and is connected with housing, and adjustment worm screw 2 is mounted in the stepped hole of housing, and is pacified
In the centre bore of adjusting nut 1, with 1 axially position of adjusting nut, adjustment gear 3 is mounted in the gear grooved of housing, with
Adjustment worm screw 2 is intermeshed, and 5 upper end of adjustment screw is machined with square pole, is engaged with the square hole for adjusting gear 3, lower end adds
Work has external screw thread (to be fixed on housing) internal thread by pin with nut below to be connected, and adjustment screw 5 can be with adjustment tooth
Wheel 3 rotates together, and is turned and is converted into axial displacement.
The adjusting nut 1 is stepped cylindrical structure, and small end cylinder is machined with external screw thread, uniformly adds in big end outer circle
Work has arc groove, and symmetrical card slot is uniformly equipped in centre bore.
2 upper end of the adjustment worm screw is machined with square foot piece, and is machined with through hole on the multi-diameter shaft below square foot piece,
Symmetrical card slot equipped with spherical backing pin and adjusting nut 1 in hole coordinates.
The spherical shape backing pin is made of spring and two balls, and two balls are mounted in the both ends of spring.
Beneficial effects of the present invention：The present invention is relatively easy, easy to operate using structure, can guarantee the corresponding production of quick adjustment
The rated speed of product.

Specific embodiment
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 2, the present invention includes housing, adjusting nut 1, adjustment worm screw 2, adjustment gear 3,4 and of lock-screw
Adjustment screw 5 adjusts the structure of worm screw 2 referring to Fig. 2.
Adjusting nut 1 is tightened in by small end external screw thread in the threaded hole of housing upper end, and is installed in big end external arc
The angularly positioning and locking of lock-screw 4 in connected in star.
When it is inverse, rotate clockwise be exposed at outside arrangements for speed regulation adjustment worm screw 2 square foot piece when, adjustment worm screw 2 drive with
The adjustment gear 3 of engagement rotate so that 5 side of the adjustment screw rotation edge in adjustment gear square hole is below
The screw thread of nut (being fixed on by pin on housing) moves up and down, and changes the governor spring (diagram of 5 lower section of adjustment screw
In do not mark) decrement, achieve the purpose that change rotating speed.It adjusts worm screw 2 in this structure to turn around, adjustment gear 3 turns over 1
Tooth, adjustment screw 5 move 0.05 millimeter of distance, scaling or compression governor spring, its corresponding rotational speed regulation up or down
The rotating speed of terminal changes 0.2%~0.3%；
As shown in Figure 3, Figure 4, adjust and be machined with through hole on the multi-diameter shaft below 2 square foot piece of worm screw, equipped with spherical backing pin,
Spherical backing pin is made of spring and two balls, and two balls are mounted in the both ends of spring, adjusts the multi-diameter shaft of worm screw 2 and adjustment spiral shell
The centre bore that mother 1 is equipped with symmetrical card slot coordinates, and when adjustment worm screw 2 rotates in the centre bore of adjusting nut 1, adjusts 2 ball of worm screw
Two balls at its both ends of the spring compression of shape backing pin, when every turn 1/6 circle of adjustment worm screw 2, two balls of spherical backing pin can
It is stuck in the symmetrical card slot of adjusting nut 1, auto lock so that can clearly feel rotation when rotating and adjusting worm screw 2
The number of turns, maintain easily user of service's memory, and achieve the purpose that fine adjustment.
As shown in figure 5, simultaneously, the principle based on this structure can pass through the diameter and tune of ball in the spherical backing pin of change
The quantity of whole 1 card slot of nut come achieve the purpose that different accuracy adjust, also can by respective combination by its segment design into what
It adjusts, makes its regulating degree more accurate.
