There is the steel ball 311 for contacting ring hypomere madial wall, a steel ball part is in ball groove, steel ball remainder is in outside ball groove,
Steel ball level can be slided in ball groove, and the ball spring 312 of axis horizontal, ball spring one end contact steel ball, ball bullet are provided with ball groove
The spring other end is contacted with ball groove inwall, and the vertical spacing of adjacent clickly tooth is consistent.
During regulation, can be judged by listening sound, be realized accurate adjustment, be explained as follows.
The inner ring surface against one of internal gear is rectified in the collision of collision bar, it is assumed that the internal gear is the first internal gear,
When turn adjusting screw, fixed angle Y is often rotated, a collision tooth is just had on internal gear inner ring surface by collision end, touched
When tooth butt is by collision end, by collision bar towards pressing in chute, and can collide after tooth leaves collision end, in the work of impact spring
With lower collision bar again the outer bullet of meeting to contact ring internal gear inner ring surface, said process can send " clickly " sound.And if first
What the screw thread (pitch) of the number of teeth and adjusting screw on internal gear inner ring surface was to determine, just can determine that and often send " clickly " sound
Adjusting screw screws in the distance of (or screw out) afterwards, also just can determine that adjusting screw inwardly promote (or outwards avoiding) steering tube away from
From operator need not observe scale, just can directly know regulated quantity.Further, since " being collided on the first internal gear inner ring surface
The number of tooth, on the second internal gear inner ring surface collide tooth number, on the 3rd internal gear inner ring surface collide tooth number
Mesh is different ", thus when the collision of collision bar rectify to internal gear it is different when, turn adjusting screw (internal gear) allows collision
Tooth goes to contact, leave collision bar and send " clickly " after a sound, the angle that each internal gear is turned over is different.
So that " number that tooth is collided on the first internal gear inner ring surface is the collision tooth on the second internal gear inner ring surface
As a example by 1/2nd of number ":The collision of collision bar is rectified during against the first internal gear inner ring surface, and adjusting screw often rotates fixation
Angle Y, send " clickly " sound;The collision of collision bar is rectified during against the second internal gear inner ring surface, and adjusting screw often rotates solid
Determine angle 2Y, can just send " clickly " sound.That is, often send " clickly " sound, in the later case (just in second
Ring gear inner ring surface) adjusting screw screws in (or screw out) distance is (just to the first internal gear inner ring surface) adjusting screw under former case
Screw in the twice of (or back-out) distance.Above two mode, it is necessary to relatively significantly be adjusted in practical operation
When, the latter can be used, regulation can faster, be more easily realized, improving regulation efficiency and simple operation (comparatively can recognize
To be quick significantly to adjust);When needing to carry out the regulation of relatively small amplitude, the former can be used, degree of regulation is higher (relative
For be regarded as accurate slightly regulation).And when internal gear number is more, selectivity also just more (each internal gear inner ring
Collision number of teeth mesh on face needs difference, if if identical, regulating effect is repeated).More conducively user is selected, and is ensured various
There is relatively reasonable, suitable regulative mode under situation.
Epimere describes different internal gears and possesses different adaptability and regulating effects, and how rapidly and accurately this section is introduced
Realize the switching (ring epimere how being moved up and down, so as to allow different internal gears to go collision bar of aliging) of each internal gear.First turn
Lower adjusting handle, because screw thread coordinates between lower adjusting handle and ring hypomere lateral wall, and ring hypomere can only move up and down (ring
Hypomere is set in fixed seat and ring hypomere is slidably connected with fixed seat, and slidably direction and the adjusting screw axis of ring hypomere are put down
OK), so can be moved up and down with rotating ring hypomere by adjusting handle under turn, so as to also drive each clickly tooth to move up and down.Often
When a clickly tooth is by steel ball, all can be by steel ball towards pressing in ball groove, and after clickly tooth leaves steel ball, in ball spring
The lower steel ball of effect again can outer bullet to contact ring hypomere madial wall, so as to sending " clickly " sound, and whenever clickly a tooth process
Steel ball, then illustrate ring hypomere rise (decline) fixed range S (S can be designed as the integral multiple of internal gear height, when S with it is each
When internal gear etc. is high, sent per adjusting handle under turn " clickly " as soon as sound, have switched an internal gear up or down),
I.e. each internal gear rises (decline) fixed range S.
The calibration structure also includes adjusting handle 5 on, and upper adjusting handle is consolidated by attachment screw with clickly linkage seat
It is fixed.The upper adjusting handle includes top cover 51, outer barrel 52, and outer barrel is vertically and outer barrel upper end is connected with top cover, in a calibration knot
In structure, outer barrel is coaxial with adjusting screw, and outer barrel covers ring epimere lateral wall.It is slidably matched between outer barrel and ring epimere lateral wall.
It is fixedly connected by screw thread between the hole wall of the fixed seat lower end and regulation fixing hole.Between fixed seat and regulating bolt
It is provided with sealing ring 6.Each structure is driven using adjusting handle carries out turn and regulation, can effectively lift regulation stability, reduces
Operation difficulty.And scale can be arranged on adjusting handle, regulation linkage ring, enhanced feature degree of integration is also convenient for auxiliary during regulation
Help observation.
