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 realized using common wrench rotation droop adjustment screw at present,
It is time-consuming and laborious when being adjusted and inaccurate, increase many difficulties to the working service in outfield.With governor technology
Development, governor flight-line service is simple and convenient to wait requirements so that governor structure tends to simplify, this device can make governor
Accurate quick feature is required in terms of outer field control.
Invention content
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 of the present invention：A kind of rotation device for precisely regulating, which is characterized in that including shell, 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 connect with shell, and adjustment worm screw 2 is mounted in the stepped hole of shell, and pacifies
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 shell, with
It adjusts worm screw 2 to be intermeshed, 5 upper end of adjustment screw is machined with square pole 9, matches with the square hole 7 of adjustment gear 3, lower end
It is machined with external screw thread and (is fixed on shell) internal thread by pin with nut below and connect, adjustment screw 5 can be with adjustment
Gear 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 adjustment worm screw is machined with rectangular foot piece 10, and is machined on the multi-diameter shaft below rectangular foot piece 10
Through-hole, the symmetrical card slot equipped with spherical backing pin 8 and adjusting nut 1 in hole coordinate.
The spherical shape backing pin 8 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 quickly adjustment
The rated speed of product.

Specific implementation mode
Present invention is further described in detail with embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 2, the present invention includes shell, 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 shell 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 speed regulation device adjustment worm screw 2 rectangular foot piece 10 when, adjustment worm screw 2 drive
The adjustment gear 3 that is engaged with rotates, to make 5 side of the adjustment screw rotation edge being mounted in adjustment gear square hole 7 its
The screw thread of lower square nut (being fixed on shell by pin) moves up and down, and changes the governor spring of 5 lower section of adjustment screw
The decrement of (not marked in diagram) achievees the purpose that change rotating speed.Worm screw 2 is adjusted in this structure to turn around, and adjusts 3 turns of gear
1 tooth is crossed, adjustment screw 5 moves 0.05 millimeter of distance, scaling or compression governor spring, its corresponding rotating speed up or down
The rotating speed for adjusting terminal changes 0.2%~0.3%；
As shown in Figure 3, Figure 4, it is machined with through-hole on the multi-diameter shaft of 2 rectangular foot piece of adjustment worm screw, 10 lower section, equipped with spherical gear
Pin 8, spherical backing pin 8 are made of spring and two balls, and two balls are mounted in the both ends of spring, adjust the multi-diameter shaft of worm screw 2 with
The centre bore that adjusting nut 1 is equipped with symmetrical card slot coordinates, when adjustment worm screw 2 rotates in the centre bore of adjusting nut 1, adjustment
Two balls of worm screw 2 and its both ends of spring compression of spherical backing pin 8 enclose for every turn 1/6, the two of spherical backing pin 8 when adjustment worm screw 2
A ball can be stuck in the symmetrical card slot of adjusting nut 1, auto lock so that can be clearly when rotation adjusts worm screw 2
The number of turns for feeling rotation maintains easily user of service's memory, and achievees 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 8 of change
The quantity of 1 card slot of whole nut achievees the purpose that different accuracy is adjusted, and 1 card slot 11 of adjusting nut of the present apparatus is 6 uniformly distributed
What its segment design can also be adjusted, keep its regulating degree more accurate by slot by the corresponding combination at.
