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 the rolling shutter door technical field, relate to a kind of elastic engaged device when being used for rolling shutter door roller blind device umbrella gear and being meshing with each other in particular.
Background technique
At present, what a lot of StoreFronts, garage adopted all is rolling shutter door, and especially door opening is bigger, and the place of ground door body is installed in inconvenience, and rolling shutter door can play convenient, fast unlatching effect.Rolling shutter door is divided into two kinds of manual rolling shutter door and electric rolling doors; Manually rolling shutter door is as the term suggests be exactly to adopt manual roller blind device to realize the unlatching of rolling shutter door, close, and for example the patent No. is the utility model patent of ZL200820115109.X, just discloses a kind of manual roller blind device; Manual roller shutter takes time and effort, speed is slow; So much human all adopts electric rolling door, for example patent No. ZL2010206655803, the applying date are described a kind of electric rolling door on December 17th, 2010, and it rotates with roller shutter driven by motor roller shutter central shaft; Realize the switch of roller shutter, open, close very fast.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 influence; Also umbrella gear is caused damage, reduced its working life.
Summary of the invention
The objective of the invention is deficiency to existing technology; A kind of umbrella gear elastic engaged device that is used for rolling shutter door is provided; When the umbrella gear with concurrent aces meshed, umbrella gear of the present invention can carry out the flexible rotation of several angle, is convenient to two umbrella gear and is meshed; Reduce and beat the tooth phenomenon, prolong the working life of umbrella gear.
In order to solve the problems of the technologies described above; Technological scheme of the present invention is following: a kind of umbrella gear elastic engaged device that is used for rolling shutter door; Comprise running shaft, umbrella gear and the joint that said running shaft, umbrella gear are coupled together; Be provided with between said running shaft and the said umbrella gear and can make said umbrella gear produce the elastic device of a circumferencial direction corner around the rotation of said running shaft elasticity, said umbrella gear is 1-3 ° around the corner that said running shaft carries out the elasticity rotation.
The applicant is through studying, test repeatedly, when finding that umbrella gear is intermeshing, its generation beat the tooth phenomenon; Be because two umbrella gear that axially intersect engagement are all rigidly fixed, and the engagement of umbrella gear only to be theoretical calculation come out; In the actual processing, because multiple reasons such as technology, process equipment and assemblings, between two umbrella gear that cause that practical set finishes and the theoretical value difference is arranged; And two gears fixing by rigidity all; This difference can't compensate, and this just causes the difficulty of two gear engagement, produces to beat the tooth phenomenon.Therefore, the applicant is provided with elastic device between umbrella gear and running shaft; Make umbrella gear to rotate a corner around running shaft, like this, with when the umbrella gear that intersects in the axle center is meshed; Umbrella gear among the present invention can the flexible rotation of carrying out a minute angle, and the tooth phenomenon is not just beaten in the engagement of being more convenient for yet; Avoid the damage of umbrella gear, prolonged its working life.
As preferably; Said elastic device comprises a torsion spring, is arranged on the chute along circumferential extension on said umbrella gear or the said running shaft; Said torsion spring one end acts on the said running shaft, and the other end acts on the said umbrella gear, and said joint one end stretches in the said chute.
As preferably, said torsion spring set is contained on the said running shaft.
As preferably; Said elastic device comprises elastomer, be arranged on said umbrella gear or the said running shaft arc groove along circumferential extension; Said joint one end stretches in the said arc groove; Said at least one end face of arc groove is provided with installation cavity, and said elastomer is installed in the said installation cavity, and said elastomer at least a portion stretches in the said arc groove.
As preferably, said elastomer is spring or elastic caoutchouc.
As preferably, two end faces of said arc groove all are provided with installation cavity.
As preferably, said joint is pin or key.
As preferably, said umbrella gear is 1-2.0 ° around the corner that said running shaft carries out the elasticity rotation.
Preferred as further, said umbrella gear is 1.5 ° around the corner that said running shaft carries out the elasticity rotation.
Beneficial effect of the present invention is:
Umbrella gear elastic engaged device of the present invention makes the umbrella gear that axially intersects better to mesh, and avoids beating the generation of tooth phenomenon, has prolonged the working life of umbrella gear.
