Embodiment
The present invention is described in further detail below in conjunction with Figure of description and embodiment.
Fig. 1 and Fig. 2 show respectively structure front view and the side view of a kind of clutch relay apparatus of the present invention, this clutch relay apparatus mainly comprises gear 1, spring case 2, live axle 3, plane scroll spring 4 and axle key 5, gear 1 is arranged on live axle 3, the side direction of gear 1 is provided with spring case 2, be provided with plane scroll spring 4 between live axle 3 and spring case 2, the inner of plane scroll spring 4 is wound on live axle 3, and the outer end is connected with spring case 2.In present embodiment, live axle 3 and gear 1 rely on the transmission that cooperatively interacts of the internal tooth 6 of axle key 5 and gear 1 on live axle, gear 1 passes through the connecting sleeve cylinder base on rolling bearing, rolling bearing is installed on live axle 3, and gear 1 is meshed with tooth bar on travelling bogie, drives the dolly advance and retreat.Plane scroll spring 4 maintains pretightening force under unloaded state, utilize the control of the setting angle of spring case and gear, adjusts the pretightening force of volute spring and the elastic force of limit position, and gear is set back, and guarantees the reliability reset.In the course of the work, can utilize automatical control system to the control of motor-driven axle position, reset in an angle on target scope when making gear unloaded, can not produce the dead point in the engagement of this angular range internal tooth wheel and rack.Utilize in addition pin that plane scroll spring 4 is hinged in live axle, means of fixation is simple and reliable.
Below in conjunction with embodiment, device of the present invention is further detailed.
Embodiment
In the present embodiment, the clutch relay apparatus is installed on the bottom driving mechanism of fuel transfer device (reactor building and fuel factory building both sides install respectively), as Fig. 5, Fig. 6 and shown in Figure 7, driving mechanism gets off the motor torque transmission through coupling, umbrella gear, live axle 3, gear 1 passes through the connecting sleeve cylinder base on the rolling bearing of live axle 3, gear 1 is meshed with tooth bar on travelling bogie, drives the dolly advance and retreat.In relay driving process, in most situations, tooth bar is to move under the driving of a gear, only when travelling bogie is about to by fuel transfer tube (two-way), just has the situation of a toothed rack while and two Gear Contacts.
In the present embodiment, the process of the driving transfer device work of clutch relay apparatus can be divided into one of four states basically, and is specific as follows:
(1) gear rack Contact
One side drive axle rotates, driving tooth bar by this side gear advances, to the moment that contacts the opposite side gear tooth, as shown in Figure 8, when travelling bogie passed through fuel transfer tube, the right side drive shaft turns drove tooth bar by this side gear and advances, to contacting the left side gear gear teeth, tooth bar needs simultaneously the Gear Contact with both sides.The gear rack Contact, when contact action power is pointed to the Gear center axis, stressed stuck phenomenon namely appears, in the present embodiment, stressed two stuck limit positions as shown in Figure 9 and Figure 10: gear teeth right side seamed edge contact situation in Fig. 9, Figure 10 gear teeth left side seamed edge contact situation, when tooth bar contacts with left side gear, can control by the stop angle of controlling live axle the stop angle of unloaded gear (the present embodiment is left gear), make unloaded gear remain on desired location shown in Figure 4, can make the gear teeth avoid meshing the dead band with contacting of tooth bar.The every 24 ° of non-engagement dead angles that possess 21.13 ° of Fig. 9 and Figure 10 middle gear in the present embodiment, the engagement dead angle of 2.87 °, as long as the deviation of gear stop position and desired location be no more than ± 10.565 °, all can successfully avoid meshing the dead band.
(2) enter complete engagement process
When tooth bar and left side gear initial contact avoided the engagement dead band after, both enter good engagement in order to allow, an adaptive process need to be arranged, be that tooth bar promotes the gear rotation, in this adaptive process, require that only left side gear is driven, the live axle of left side gear inside is static.Tooth bar under the driving of right side gear to the left gear advance, do being rotated counterclockwise under left side gear after contact will the drive at tooth bar, the hyperspace of the plane scroll spring of left side clutch has guaranteed carrying out smoothly of engagement process.In the present embodiment, the clutch relay apparatus provides clockwise, amounts to the hyperspace of 290 ° on counter clockwise direction: as reference point, the angle from the axle teeth to the wheel teeth is in the counterclockwise direction with axle teeth (axle key)
Be clutch hyperspace in the counterclockwise direction, as shown in figure 11.Angle from the axle teeth to the wheel teeth is in the clockwise direction
Be clutch hyperspace in the clockwise direction.
According to the directional characteristic of clutch, in conjunction with the direction of advance of tooth bar, select suitable clutch setting, the hyperspace of respective direction is provided.Select being set to of left side clutch: volute spring is rotated counterclockwise, and unloaded wheel teeth will be close to the counter clockwise direction side (left side) of live axle, at this moment,
When under the drive of gear at tooth bar, the position during with respect to zero load has rotated 140 °, can be considered and enter complete engagement, this moment, the live axle of left side gear started, and the live axle on right side is still kept original rotating speed, enters two drive conditions.
(3) two driving processes
After entering two driving processes, the left side live axle begins startup and is rotated counterclockwise, and rotating speed is higher than the right side live axle, in this process, keep right side drive shaft right side gear, right side gear to drive tooth bar, rack drives left side gear, the counterclockwise hyperspace of left side clutch
Reduce, until become 0.After an of short duration transient time, higher than the right side drive shaft speed, complete the switching of drive condition, that is: due to the left side drive shaft speed
Right side drive shaft right side gear, right side gear drive tooth bar, rack drives left side gear →
Left side drive shaft left side gear, left side gear drives tooth bar, rack drives right side gear;
Counterclockwise hyperspace when the left side clutch
Become at 0 o'clock, left side gear changes left side gear into by rack drives and drives.In process, keep left side drive shaft left side gear, left side gear to drive the state of tooth bar, rack drives right side gear afterwards.Simultaneously, right side clutch
Constantly increase by 0 °,
Constantly reduce by 290 °, until tooth bar breaks away from right side gear.
(4) tooth bar disengaging gear → preparation next time enters engagement
After tooth bar broke away from right side gear, the right side live axle continued rotation, stops to desired location.In this process, due to the active force of volute spring, gear will be done with respect to live axle and be rotated counterclockwise, and complete to reset.After live axle was static, the clutch after resetting was that tooth bar engagement again from left to right is ready.
Obviously, those skilled in the art can carry out various changes and modification and not break away from the spirit and scope of the present invention the present invention.Like this, if within of the present invention these are revised and modification belongs to the scope of claim of the present invention and equivalent technology thereof, the present invention also is intended to comprise these changes and modification interior.
