Abstract
The utility model discloses a contactless wedge block type large coaster for speed reducer of loading machine belonging to the technical field of mechanical transmission device. The coaster is mainly characterized technically in that a centrifugal heterotype wedge block, a positioning column and a spring are arranged between an external ring and an internal ring of a gear; when the internal ring runs at a high speed and a speed difference is generated between the internal ring and the external ring of the gear, the centrifugal heterotype wedge block runs together with the internal ring. The external ring of the gear is separated from the internal ring of the gear after the centrifugal force overcomes the resisting force of the spring with generating the gap so as to lead the external ring not to contact with the internal ring. The utility model has a reasonable structure design and simple manufacturing technique. The centrifugal heterotype wedge block is used for replacing the original roller, thus enabling the coaster to flexibly work. Moreover, the coaster can bear larger torsion force and impact force and can work for a long time under the situations of high speed and large load.
Description
One, technical field
The utility model relates to a kind of clutch, relates in particular to a kind of loader speed reducer with the big free wheel device of non-contact wedge formula, belongs to mechanical transmission.
Two, background technique
Clutch has been widely used in the mechanical transmission technical field, can be mainly used in industry systems such as automatic production line, printing machinery, package packing machine, medical machinery, textile manufacturing machine, Hoisting Machinery, Transport Machinery, food machinery, automobile, lathe.The clutch that uses is of a great variety now, the clutch that specifically is applied in the engineering vehicle speed reducer mainly is the star wheel type free wheel device, the star wheel type free wheel device is that its periphery five equilibrium is processed into 20-24 roller working surface from its structural feature, and at each roller working surface by the fixing working position of roller in clutch of spring, guarantee the uniform and outer ring of roller, inner ring contacts with rolling, this star wheel type free wheel device has the characteristics such as flexible of using, but star wheel type free wheel device, the manufacturing process complexity, bearing torque is little, and working life is short.To be processed into 20-24 roller working surface to its circumferential surface five equilibrium, roller when work stressed simultaneously and in full accord be to be difficult to ensure, in use, along with various motions are inconsistent in the degree of wear under the different situations, the stationarity and the reliability of clutch work are a greater impact.
Three, summary of the invention
The purpose of this utility model just is to provide a kind of reasonable in design, manufacturing process is simple, functional reliability is strong, bearing torque is big, can realize that under surmounting state voussoir does not contact with the inside and outside ring working surface in the clutch, the loader speed reducer that the increases the service life big free wheel device of non-contact wedge formula.
For achieving the above object, the utility model can be realized by following scheme: the loader speed reducer big free wheel device of non-contact wedge formula, comprise gear outer ring and inner ring, between gear outer ring and inner ring one circumferential clearance, be provided with centrifugal special-shaped voussoir and reach to fixing the retainer and the spring of centrifugal special-shaped voussoir.The centrifugal special-shaped voussoir that is located between gear outer ring and the inner ring is the non-cylinder of band eccentric circle.Produce centrifugal special-shaped voussoir behind certain speed difference and together turn round with inner ring and be blocked in certain position after producing centrifugal force and overcoming the resistance of spring when the rotating speed of inner ring surpasses the gear outer ring, realize non-contact with gear outer ring and inner ring working surface.When dropping to certain numerical value rear spring, speed difference again centrifugal special-shaped voussoir is got back to the wedging state, and the beginning transmitting torque.
The utility model has the advantages that: reasonable in design, manufacturing process is simple, the strong bearing torque of functional reliability is big, especially can realize the non-contact of gear outer ring, inner ring working surface and centrifugal special-shaped voussoir when not needing bearing torque again, makes wearing and tearing reduce to zero when running up.Under the situation of high-speed overload, increase the service life.Centrifugal special-shaped voussoir is linked as a combiner with retainer and spring and locating column and can makes the utility model be in best working state and do not need to change intrinsic any relative dimensions.
The utility model changes former roller into behind the centrifugal special-shaped voussoir loader is used big free wheel device bearing torque and increases substantially, and the wearing and tearing of the nothing when having realized not transmitting torque, so prolong working life, fundamentally solved the problem that long-term puzzlement exists with big free wheel device at loader.
