300kg, and can not be inverted carrying, safety coefficient is low, and during for heavy door, theft-resistant link chain, bearing installation need to be set on door body top
Precision is low, limits the decorative structure of door.And at present for hotel, banquet hall etc. some hide plates between door body, up to 9900mm, door
Body dead load reaches 490kg, and door leaf is designed with diamond cut face because of finishing requirements, and moulding protrudes door body 180mm, and door leaf will
Setting Reflecting light groove is sought, door body limited in rotation can not use traditional bearing.To solve the above problems, new-type heavy type need to be researched and developed again
Door eccentrically weighted shaft mechanism.
The content of the invention
Purpose in the utility model is to provide a kind of eccentrically weighted shaft mechanism for heavy door, to solve existing decoration
The problems of heavy door.
It is used for the eccentrically weighted shaft mechanism of heavy door in the utility model, for installing ultra-large type door body, it includes up and down
Two eccentrically weighted shaft mechanisms for being mirrored into installation, each eccentrically weighted shaft mechanism includes at the top of door body or bottom
Eccentric armshaft, the bearing base being connected with ceiling or ground, the eccentric armshaft are mirrored into by eccentric body shaft, upper and lower two
The SKF pressure bearings of installation are rotatablely connected with spring bearing, and one end of the spring bearing is fixedly connected with the bearing base,
The other end positions via stationary gland and fastening bolt to the eccentric body shaft, SKF pressure bearings, and the eccentric armshaft connects
Rotated together with the eccentric body shaft, but the eccentric body shaft and the eccentric armshaft are not in the same plane.
The spring bearing is integrally formed with the bearing base.
The eccentric body shaft is cylindrical, and centre is provided with the through hole for spring bearing insertion, and in two side ends
Through hole is respectively formed for placing the accommodating of the SKF pressure bearings formed with two-stage step in the eccentric body shaft two side ends
Space, the eccentric armshaft are fixedly connected with the columned eccentric body shaft.
The spring bearing is in one end of the close bearing base formed with for abutting the convex of the SKF pressure bearings
Ring.
The eccentric armshaft is L-shaped, is made up of orthogonal long-armed and galianconism, and long-armed fixed with the door body connects
Connect, tangent line of the galianconism along the eccentric body shaft and the eccentric body shaft are integrally formed.
Eccentrically weighted shaft mechanism in the utility model is by means of the low rolling resistance SKF of two between eccentric body shaft and spring bearing
The opposed installation of tapered pressure bearing, solves traditional bearing low bearing capacity, rolling hinders big and reverse mounted problem, single SKF bearings
27kn, dynamic 24.2kn can be reached by bearing static load, i.e., in the case where not using complex superposition to support, eccentric body shaft
Can load-bearing 2.4T weight.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in further detail.
It is big and eccentric that eccentrically weighted shaft mechanism in the utility model for heavy door is used to solving low bearing capacity, rotary resistance
Torsion problem.
As depicted in figs. 1 and 2, the eccentrically weighted shaft mechanism in the utility model for heavy door is used to install ultra-large type door body
1, upper and lower two top and bottoms installed in door body 1 for being mirrored into installation, when opening with closure heavy door, eccentrically weighted shaft machine
Structure rotates together with large-scale door body 1.So make to move outside the center of rotation of door body 1, door body 1 does not influence periphery decoration when rotating is made
The structure of type 10, surface layer structure, light trough structure conflict with base layer structure when solving the rotation of door body 1.
As shown in Figure 3 and Figure 4, each eccentrically weighted shaft mechanism includes the eccentric shaft installed in the top of door body 1 or bottom
Arm 2, the bearing base 4 being fixedly connected with ceiling or ground 3, eccentric body shaft 5, two SKF pressure bearings 6, spring bearings 7.
Eccentric armshaft 2 is L-shaped, is made up of orthogonal long-armed 20 and galianconism 21, and long-armed 20 are fixedly connected with door body 1, the edge of galianconism 21
The tangent line of eccentric body shaft 5 and eccentric body shaft 5 are integrally formed, can also be fixedly connected.Enable eccentric armshaft 2 with eccentric body shaft 5
Rotation and rotate.
In the centre of eccentric body shaft 5 formed with the through hole 22 worn for spring bearing 7, and respectively formed at the both ends of through hole 22
There is two-stage step 23, form the accommodation space for placing SKF pressure bearings 6, two SKF pressure bearings 6 in upper and lower mirror image
Install in the accommodation space, one end of spring bearing 7 is fixedly connected with ceiling or ground 3, and the other end is through first successively
With the 9 sealed fixation of stationary gland 8 and fastening bolt after 22, second SKF pressure bearings 6, through hole SKF pressure bearings 6.Support shaft
7 are held in one end of close bearing base 4 formed with the bulge loop 11 for abutting SKF pressure bearings 6.One end of spring bearing 7 with
Bearing base 4 is fixedly connected or integrally formed, the other end via stationary gland 8 and fastening bolt to eccentric body shaft 5,
SKF pressure bearings 6 are positioned.
In summary, the medium and heavy door pivot structure of the utility model is mirrored into installing for two up and down, and upper and lower two are divided respectively
The weight of door body 1 is carried on a shoulder pole, solves the problems, such as traditional bearing theft-resistant link chain, the door body weight that can be born reaches 4.8T, more than traditional rotating shaft
More than 10 times of load-bearing.Due to using SKF tapered pressure bearings so that broken away from the rotary resistance of conventional slip bearing by structure weight
The influence of power, it can accomplish to open 490kg door body using only more than ten Ns of strength.Simultaneously as used in eccentric body shaft 5
SKF tapered pressure bearings, the rotary resistance of bearing are far below conventional slip bearing.
