Abstract
The utility model discloses a chain anti-skidding device, which comprises a chain mounted on a sprocket. Guard wings preventing the chain skidding are arranged on lateral edges of two sides of the sprocket and combined with the sprocket to form a groove, and sprocket teeth arranged on the sprocket are arranged in the central position of the groove. When the chain normally runs, the clearances with same distances are formed between two-side guard wings and the chain. When the chain deviates from the normal running rail, the guard wings can retain the chain back, and then the chain is still engaged with the sprocket teeth normally, so that the chain-skidding process is broken, and the chain skidding is avoided radically.
Description
Technical field
The utility model relates to a kind of chain anti-skid device.
Background technology
Motor bike on the market, bicycle and the vehicle or the machinery that rely on chain gear in time do not tighten when the chain looseness is excessive, when perhaps engagement is tight after chain, the sprocket wheel wearing and tearing, the slot phenomenon take place easily.The mechanism of slot is: vehicle or machinery are in operational process, the chain that is positioned at sprocket wheel top is tensioned and stretches owing to bearing pulling force, make bottom chain sagging, when uneven or turning centre-of gravity shift and operation produce vibrations when the road surface, the sprocket wheel bottom is returned chain and is departed from normal orbit, chain can not with sprocket engagement, each bitch chain bar also and then breaks away from sprocket after causing, and slot takes place.Slot not only delays stroke, influences operation, and very easily produces danger, causes motor bike driver and crew's the person and property damage.The motor bike navigating mate has only the engagement of irregular adjustment chain and sprocket wheel in order to reduce slot, finds to change when chain and sprocket wheel do not conform to tooth chain and sprocket wheel at once.The non-skid feature stability of above-mentioned chain, poor reliability, it is entail dangers to driver and crew's life security that carelessness is arranged slightly, and the implementation process trouble, has quickened the loss of parts.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, safe and convenient to use and chain anti-skid device of prolonging the service life of parts greatly is provided.
Goal of the invention of the present utility model is achieved in that a kind of chain anti-skid device, comprise the chain that is installed on the sprocket wheel, it is characterized in that: described sprocket wheel both side edges is provided with the flap parallel with chain, and described flap and sprocket wheel form groove, and chain is installed in the groove.
Described flap is the cyclic metal piece concentric with sprocket wheel.
The described sprocket of being located on the sprocket wheel is positioned on the center of groove.
Described flap is installed on the sprocket wheel lateral margin by screw.
Described flap is installed on the sprocket wheel lateral margin by rivet.
Described flap is welded on the sprocket wheel lateral margin.
Described flap and sprocket wheel are by casting integrated moulding.
The utility model improves the chain anti-skid device of prior art, on the sprocket wheel lateral margin, be provided with the flap that prevents slot, this flap is positioned on the lateral margin of two sides of sprocket wheel, flap and sprocket wheel form groove, the flap outer rim is greater than the tip diameter of sprocket, and the sprocket of being located on the sprocket wheel is positioned on the center of groove.When chain normally moves, the gap of equidistance is respectively arranged, between two side flaps and the chain when chain departs from normal orbit, flap will go back the chain retaining, make still normal engaged of chain and sprocket, interrupt the process of slot, fundamentally avoid slot.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment;
Accompanying drawing 2 is the structural representation of the utility model side.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in Fig. 1 and 2, chain anti-skid device of the present utility model comprises the chain that is installed on the sprocket wheel 1, and sprocket wheel 1 is provided with the sprocket 2 with chain engages.Sprocket wheel 1 lateral margin is provided with the flap parallel with chain 3, and this flap 3 is the cyclic metal piece concentric with sprocket wheel 1.The thickness of flap 3 has guaranteed that flap 3 has enough mechanical strengths, this flap 3 usefulness steel plate punching presses or make with the material with sufficient mechanical strength.Flap 3 is positioned on the lateral margin of 1 two sides of sprocket wheel, and flap 3 forms groove with sprocket wheel 1, and the sprocket of being located on the sprocket wheel 12 is positioned on the center of groove, and the external profile diameter of flap 3 is greater than the tip diameter of sprocket 2, and the sprocket 2 in chain and the groove meshes.Between chain in groove and two flaps 3 equidistant gap is arranged, the gap of 0.9mm～1.1mm is respectively arranged between two side flaps 3 and the chain, avoid influencing the chain running velocity and increase wearing and tearing.When chain departed from normal orbit, flap 3 kept off back chain, makes chain and sprocket 2 normal engaged, interrupted the process of slot, fundamentally avoided the generation of slot.Flap 3 can be fastening by screw, the mode of welding manner or rivet clasp is fixed on sprocket wheel 1 both side edges, flap 3 also can with sprocket wheel 1 integral casting forming.Chain anti-skid device of the present utility model be installed on usually vehicle or machinery driven sprocket on (slot generally can not take place in the drive sprocket of vehicle, because returning chain part is sent by drive sprocket, again around last driven sprocket), but also can on the sprocket wheel of front and back, install simultaneously.Use chain anti-skid device of the present utility model, not only improve the safety of chain gear greatly, can also reduce the trouble that the user need adjust chain at any time, reduce psychological burden because of worrying that at any time slot occurs; Use chain anti-skid device of the present utility model, do not need often to tighten chain, can reduce the wearing and tearing of chain and sprocket wheel 1, prolong the service life of chain and sprocket wheel 1; Use chain anti-skid device of the present utility model, therefore the user has also saved the expense of parts maintenances.
