Description
Technical field
The utility model belongs to mechanical field, and especially a kind of silent ratchet is applied to the rotatingshaft of rotating machinery to lock and separation.
Background technique
In production application at present, locking device to rotatingshaft kind equipment, normally by installing perpendicular to the brake wheel of rotatingshaft and along brake wheel, band-type brake be radially installed in rotary shaft end, surface friction drag when holding tightly between brake wheel and band-type brake prevents from becoming flexible, realize rotating machinery brake and keep rotatingshaft to fix, when rotatingshaft driving torque is greater than reverse resistive torque, occur that rotatingshaft rotates.There is at present the locking mechanism of other form, but action principle is all to increase a counter-rotational moment of torsion of prevention equipment, stop equipment moving, other locking mechanism has bolt-type, when equipment moving arrives a certain position, need just to fix and with latch, equipment is locked, but this kind equipment is because having relatively high expectations lockhole position and coordinating of lock pin, can not realize arbitrary position and lock at random.
Model utility content
The purpose of this utility model provides a kind of silent ratchet, for locking the rotatingshaft of rotating mechanism, when equipment rotatingshaft will move, it is separated that locking mechanism and rotatingshaft are easy to, and the not motion of interference rotation axle, when rotatingshaft will be locked, discharge locking mechanism, realize rotatingshaft and locking mechanism is connected, the special design by locking mechanism produces along the axial resistance to rotatingshaft of rotatingshaft, realizes locking and prevents from becoming flexible.
The technological scheme of model utility:
A silent ratchet, it comprises rotatingshaft, lock shaft, friction pin, locking nut, handle with sleeve, fixed base, and locking nut is connected with fixed base, and lock shaft, friction pin, handle with sleeve are connected, and rotatingshaft, lock shaft are flexibly connected.
Locking end and the lock shaft of described rotatingshaft are connected by hexahedron.
Described locking nut and fixed base are realized friction lock by the clamping to friction pin.
1, by rotatingshaft multiaspect is connected, prevent that rotatingshaft is under torsional interaction, overcome coupling mechanism force and rotate.
2,, by six contacts of spring pressure and fitting surface, realize fitting surface centering in locking process, and fully contact coordinates.
3, by locking nut is screwed, to realize friction pin is increased to axial pressure, pressure changes the surface friction drag to friction pin into, stops friction pin motion, realizes and prevents from becoming flexible, and increase with the power that screws of locking nut, and surface friction drag trend is infinitely great.
4, locking nut is realized locking mechanism and is easy to separated and locking with rotatingshaft.
5, when locking mechanism is separated, friction pin is in safety groove position, and separated failure phenomenon appears in the equipment of preventing, increases safety in utilization.
6, there is coupling mechanism force large, be difficult for the features such as loosening.
Accompanying drawing explanation
Fig. 1 a is the locking state three-dimensional view of silent ratchet;
Fig. 1 b is the separated state three-dimensional view of silent ratchet;
Fig. 2 a is the locking state structural representation of silent ratchet;
Fig. 2 b is the locking state sectional view of silent ratchet;
Fig. 3 is the separated state structural representation (comprising broken section) of silent ratchet.
In figure, rotatingshaft 1, lock shaft 2, friction pin 3, locking nut 4, handle with sleeve 5, fixed base 6.
Embodiment
The utility model is by the particular design of locking mechanism, realize by increasing the axial pressure of rotatingshaft, the friction lock of realization to rotatingshaft kind equipment, overcome the deficiency of the band brake type locking existence of traditional locking mechanism, realize rotating shaft locking at an arbitrary position, be a kind of novel locking mechanism, be applied to the locking of rotatingshaft kind equipment, there is larger marketing using value.
As Fig. 1 a, 1b, shown in Fig. 2 a, 2b, a kind of silent ratchet, it comprises rotatingshaft 1, lock shaft 2, friction pin 3, locking nut 4, handle with sleeve 5, fixed base 6, locking nut 4 is connected with fixed base 6, lock shaft 2, friction pin 3, handle with sleeve 5 are connected, and rotatingshaft 1, lock shaft 2 are flexibly connected.
Locking end and the lock shaft 2 of described rotatingshaft 1 are connected by hexahedron.
Described locking nut 4 and fixed base 6 are by realizing friction lock to the clamping of friction pin 3.
application Example:
Locking mechanism separated state as shown in Figure 3, rotatingshaft 1 is separated with locking mechanism, now friction pin 3 is in the safety groove of locking nut 4, in the time of need to locking, handle with sleeve 5, friction pin 3 turns to locking nut 4 axial groove positions from the position of safety groove shown in Fig. 3, lock shaft 2 moves upward under spring pressure effect, realizing rotatingshaft 1 contacts with lock shaft 2, under spring pressure effect, lock shaft 2 rotates centering voluntarily, realize locking mechanism and rotatingshaft 1 is connected, when friction pin moves up to fixed base 6 screw bottom surface, stop motion, realizing rotatingshaft 1 fully coordinates and contacts with lock shaft 2, now rotation lock nut 4, when turning to several angle, realize 6 pairs of friction pin 3 friction grip of locking nut 4 and fixed base, under locking nut 4 and the locking drag effect of fixed base 6 matching thread, the locking of realization to rotatingshaft 1.After locking, state is shown in shown in Fig. 2 a, 2b.
