Abstract
The invention discloses a bevel gear elastic meshing device for a roller shutter door, which comprises a rotating shaft, a bevel gear and a connecting part for connecting the rotating shaft with the bevel gear, wherein an elastic device, which can cause the bevel gear to elastically rotate around the rotating shaft so as to form a turning angle along a peripheral direction, is arranged between the rotating shaft and the bevel gear. The bevel gear elastic meshing device provided by the invention can cause the bevel gears which are axially intersected to more effectively mesh; the tooth breaking phenomenon is avoided; and the service life of the bevel gears is prolonged.
Description
Technical field
The present invention relates to rolling shutter door technical field, relate in particular a kind of elastic engaged device intermeshing for rolling shutter door roller blind device umbrella gear time.
Background technique
At present, what a lot of StoreFronts, garage adopted is all rolling shutter door, and especially door opening is larger, the place of inconvenient installation ground door body, and rolling shutter door can play convenient, fast unlatching effect.Rolling shutter door is divided into two kinds of hand rolling door and electric rolling doors, hand rolling door is as the term suggests be exactly to adopt Manual curtain rolling device to realize the unlatching of rolling shutter door, close, the utility model patent that for example patent No. is ZL200820115109.X, disclose a kind of Manual curtain rolling device, hand curtain rolling takes time and effort, speed is slow, so a lot of people adopt electric rolling door, for example patent No. ZL2010206655803, the applying date is a kind of electric rolling door described in 17 days December in 2010, it drives roller shutter central shaft to rotate with rolling motor, realize the switch of roller shutter, open, close very quick.The roller blind device of rolling shutter door, adopts intermeshing umbrella gear as power transmission, still sometimes, when existing umbrella gear is intermeshing, can produce the phenomenon of beating tooth, the not only normal engagement of impact, also umbrella gear has been caused to damage, reduced its working life.
Summary of the invention
The object of the invention is for the deficiencies in the prior art part, a kind of umbrella gear elastic engaged device for rolling shutter door is provided, in engaging with the umbrella gear of concurrent aces, umbrella gear of the present invention can carry out the flexible rotation of several angle, being convenient to two umbrella gear is meshed, reduce and beat tooth phenomenon, extend the working life of umbrella gear.
In order to solve the problems of the technologies described above, technological scheme of the present invention is as follows: a kind of umbrella gear elastic engaged device for rolling shutter door, comprise running shaft, umbrella gear and the joint that described running shaft, umbrella gear are coupled together, between described running shaft and described umbrella gear, be provided with the elastic device that can make described umbrella gear produce a circumferencial direction corner around described running shaft elastic rotary, the corner that described umbrella gear carries out elastic rotary around described running shaft is 1-3 °.
The applicant is through repeatedly studying, testing, when finding that umbrella gear is intermeshing, its generation beat tooth phenomenon, because two axially intersect the umbrella gear of engagement, all rigidly fixed, and being only theory, the engagement of umbrella gear calculates, in actual processing, because the many reasons such as technique, process equipment and assembling, cause between two complete umbrella gear of practical set and theoretical value and have difference, and all fixing by rigidity of two gears, this difference cannot compensate, the difficulty that this just causes two gear engagements, produces and beats tooth phenomenon.Therefore, the applicant is between umbrella gear and running shaft, be provided with elastic device, make umbrella gear to rotate a corner around running shaft, like this, when the umbrella gear crossing with axle center is meshed, umbrella gear in the present invention can the flexible rotation of carrying out a minute angle, and tooth phenomenon is not just beaten in the engagement of being more convenient for yet, avoid the damage of umbrella gear, extended its working life.
As preferably, described elastic device comprises a torsion spring, is arranged on the chute along circumferential extension on described umbrella gear or described running shaft, described torsion spring one end acts on described running shaft, and the other end acts on described umbrella gear, and described joint one end is stretched in described chute.
As preferably, described torsion spring set is contained on described running shaft.
As preferably, described elastic device comprises elastomer, is arranged on the arc groove along circumferential extension on described umbrella gear or described running shaft, described joint one end is stretched in described arc groove, described at least one end face of arc groove is provided with installation cavity, described elastomer is arranged in described installation cavity, and described elastomer at least a portion stretches in described arc groove.
As preferably, described elastomer is spring or elastic caoutchouc.
As preferably, two end faces of described arc groove are all provided with installation cavity.
As preferably, described joint is pin or key.
As preferably, the corner that described umbrella gear carries out elastic rotary around described running shaft is 1-2.0 °.
As further preferred, the corner that described umbrella gear carries out elastic rotary around described running shaft is 1.5 °.
Beneficial effect of the present invention is:
Umbrella gear elastic engaged device of the present invention, can better engage axially crossing umbrella gear, avoids beating the generation of tooth phenomenon, has extended the working life of umbrella gear.
