Abstract
The utility model proposes a kind of while steady devices for pre-tightening second belt, increase rubber column driving to be connected in the mobile slide block mechanism of body, the hysteresis loop of rubber keeps consistent with the hysteresis loop of belt.Ensure belt in the moment of commutation by rubber column, the spring energy of rubber column effectively makes up commutation moment slack list and pilled-in selvedge mutually converts the mutation of bring transmission force, so that the power of motor transmitting smoothly passes through belt and is transmitted to movement mechanism, midway, which does not increase, is not also reduced.Combination according to angular bisector theorem, rubber column buffering and adjusting slider mechanism, simplify pre-tightening mechanism, the influence of the power transmitted by spring pre-tightening bring mutation power to belt is avoided, while also reducing cost of manufacture, improves the working efficiency of transmission ratio accuracy and transmission.
Description
Technical field
The utility model relates to a kind of while steady devices for pre-tightening second belt, belong to belt transmission field, especially
Second belt deceleration transmission field.
Background technique
In the application of existing second belt deceleration transmission, setting up has three groups of wheels to form an angle, a respectively step cone,
The structure type of two step cones and gear set.Generally two wheels are fixed, using a wheel group tightening belt, commonly use intermediate gear
Group is adjusted and (also has and be adjusted using non-gear set).Gear set fixing seat conventional arrangement is strip-shaped hole (linear regulation)
Or waist-shaped hole (arc adjusting), then cooperate certain mechanical tensile forces, by belt tension.Part design can be in the base of mechanical tensile forces
On plinth, addition spring auxiliary guarantees the tensile force ratio of belt smoothly.
Such as the Chinese patent 201610594786.3 of applicant's earlier application, proposes a kind of while pre-tightening two-stage belt
Device passes through adjusting using angular bisector theorem (both sides at any point to this angle on angular bisector are equidistant)
The shaft position mode of level-one bull wheel solve the problems, such as and meanwhile uniformly pre-tighten two-stage belt, simplify pre-pressing structure, eliminate because
Tensioning wheel or pinch roller squeeze influence of the bending to belt life caused by belt, while also improving the accuracy of transmission ratio
With the working efficiency of transmission.
But applicant has found in actual use, and for belt in prolonged operating, spring will appear fatigue, exist
The possibility of structural failure；And when motor commutation, that is, the slack list for belt transmission occur becomes pilled-in selvedge, and pilled-in selvedge fluffs process wink on side
Between, the size and Orientation moment of power occurs reversed on driving belt, and it is unfavorable that transmission stability and service life to belt have
It influences.Especially in some fields for needing accurately to control, as boat-carrying communication in moving system ACU antenna control unit in, due to antenna
It is directed toward and needs to be controlled to satelloid, so control motor is frequently necessary to commutation control, belt traditional at this time in stormy waves
Transmission just may require that forward and reverse commutation.Due to the hysteresis attribute of belt own material, when only with pretightning force device cooperation spring
When, the transmission force that will cause belt mutates, it cannot be guaranteed that the transmitting of the stationarity of power, the prolonged power that is mutated will reduce skin
The service life of band, and it is unable to satisfy the control accuracy requirement of accurate control equipment.
