Abstract
The utility model relates to a zero sliding friction one-way driving clutch, which belongs to the technical field of machines. The utility model is mainly composed of an outer sleeve, ratchet pawls and an inner shaft sleeve, wherein, the inner well of the outer sleeve is provided with ratchets, and the ratchet pawls are arranged on the inner shaft sleeve. Under the free state, at least one ratchet pawl is always in the trend of meshing with the ratchet under the action of gravity, which can ensure that the inner shaft sleeve is driven by the outer sleeve to rotate slowly by the ratchet pawls during barring. During normal running, the inner shaft sleeve rotates at high speed, the pawl ends of the ratchet pawls are separated from the ratchets under the action of the centrifugal force, the other ends are not contacted with the ratchets, and the zero friction of the ratchet pawls and the ratchets can be achieved. The utility model has the advantages that the ratchet pawls and the ratchets are in the zero friction state during normal running, and the service life of the clutch can be increased; the utility model also has the advantages of simple structure, easy fabrication, low cost, and excellent market competitive power.
Description
(1) technical field: the utility model relates to field of mechanical technique, particularly a kind of zero sliding friction one-way drive clutch.
(2) background technique: unidirectional drive plate and car clutch are one of essential parts of chemical machine (centrifuge etc.), and internal axle sleeve runs up during normal operation, and overcoat does not change; During maintenance, drive internal axle sleeve slowly run (jiggering) by overcoat.
The jiggering clutch configuration complexity of external import costs an arm and a leg, and is made up of several voussoirs between the overcoat in it, and is full of lubricant oil, therefore requires clutch that reliable sealing must be arranged, and has increased the difficulty of processing of part.And during the internal axle sleeve high speed rotating, voussoir and overcoat still have friction, have quickened the wearing and tearing of voussoir and overcoat, finally cause the shortening of whole life of clutch.
(3) summary of the invention: for overcoming the above-mentioned defective of prior art, the technical solution that the utility model is taked is: this clutch mainly is made of overcoat, internal axle sleeve and ratchet, the inwall of overcoat is provided with ratchet, realizes the transmission of overcoat and internal axle sleeve by ratchet, ratchet.Ratchet is to be the asymmetrical shape of symmetry axis with the axle center, the quality of pawl end is less than the other end, during free state, have at least a ratchet to be in trend with ratchet engagement all the time under the effect of gravity, overcoat drives internal axle sleeve by ratchet and slowly rotates in the time of also guaranteeing jiggering; During normal the operation, the internal axle sleeve high speed rotating, the pawl end of ratchet separates with ratchet under action of centrifugal force, and the other end does not contact (by the structure shape decision) yet with ratchet, promptly realized zero friction of ratchet and ratchet.
Ratchet and ratchet zero friction when the beneficial effects of the utility model are normally to move, the working life of having improved clutch greatly.Because it is simple in structure, easily manufactured, cost is lower, and the very strong market competitiveness is arranged.
(4) description of drawings: Fig. 1 is a structural representation of the present utility model.
(5) embodiment: as can be known referring to Fig. 1, the utility model mainly is made of overcoat 1, internal axle sleeve 2 and ratchet 3, and the inwall of overcoat 1 is provided with ratchet 4, and ratchet 3 is to be the asymmetrical shape of symmetry axis with the axle center, the quality of ratchet end is less than the other end, and ratchet 3 is installed on the internal axle sleeve 2.
Claims (1)
1, a kind of zero sliding friction one-way drive clutch mainly is made of overcoat (1), internal axle sleeve (2) and ratchet (3), the inwall that it is characterized in that overcoat (1) is provided with ratchet (4), ratchet (3) is to be the asymmetrical shape of symmetry axis with the axle center, the quality of ratchet end is less than the other end, and ratchet (3) is installed on the internal axle sleeve (2).
