Description
Technical field
The utility model is related to Castor structure technical fields, specifically, it shows a kind of shock resistance caster bracket.
Background technology
Ball-type is mostly used using trundle bracket steering at this stage, does raceway, raceway respectively on mounting plate and wheel support
Mounting plate and wheel support are riveted with axis pin after upper grease arrangement ball, turn-around machine is constituted by ball and upper and lower raceway at middle part
Structure；Trundle bracket not only carry it is small, it is complicated, and will appear after long-time use turn to clamping stagnation it is laborious situations such as.
Therefore, it is necessary to provide a kind of shock resistance caster bracket to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of shock resistance caster bracket.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of shock resistance caster bracket, including universal wheel mounting plate assembly, universal wheel lower bracket assembly；The universal wheel
Mounting plate assembly is formed by fixedly connecting by universal wheel mounting plate and bearing inner race, and the universal wheel lower bracket assembly is by bearing outer ring
It is formed by fixedly connecting with universal wheel lower bracket；It is provided with several groups ball grooves between the bearing inner race and the bearing outer ring, one
It is provided with bearing ball between the ball grooves that group is correspondingly arranged.
Further, it is provided on the bearing outer ring and fills out the hole of bead, described fill out on pearl sky is provided with obturator.
Further, the pore size between ball grooves described in one group be correspondingly arranged is the sphere diameter of the bearing ball
103%-105%。
Further, the upper surface of the bearing inner race is higher than the upper surface of the bearing outer ring, under the bearing outer ring
End face is less than the lower face of the bearing inner race.
Further, the colloid for further fit sealing is provided with outside the obturator.
Compared with prior art, the utility model between fixed body and rotor by being respectively welded in swing mechanism
Outer ring, and two total members after welding can be dismounted easily, and rolling element is installed to inner ring, the outer ring of swing mechanism
Afterwards, the reliable swing mechanism of connection can be formed, the function of revolution and bearing is realized, larger load and impact can be born, and
Rotation is flexible, durable；Can be widely used in the universal wheel of various structure and sizes, for replace now it is complicated or
The bearing capacity of universal wheel can be improved in the caster bracket of person's fragility, and impact resistance, rotation are flexible, and service life is long.
Description of the drawings
Fig. 1 is the structural schematic diagram of the embodiments of the present invention.
Fig. 2 is the structural schematic diagram of the embodiments of the present invention.
Specific implementation mode
Embodiment：
Refering to fig. 1-2, the present embodiment shows a kind of shock resistance caster bracket：
Including universal wheel mounting plate assembly 1, universal wheel lower bracket assembly 4；1 assembly of universal wheel mounting plate is installed by universal wheel
Plate 1.1 and bearing inner race 1.2 are formed by fixedly connecting, and universal wheel lower bracket assembly 4 is by bearing outer ring 4.1 and universal wheel lower bracket
4.2 being formed by fixedly connecting；Several groups ball grooves, one group of rolling being correspondingly arranged are provided between bearing inner race 1.2 and bearing outer ring 4.1
Bearing ball 2 is provided between pearl slot.
It is provided on bearing outer ring 4.1 and fills out the hole of bead, filled out on pearl sky and be provided with obturator 3.
Bearing ball 2 between device enters the gap between group ball grooves one by one, is waited after being attached to suitable quantity, uses obturator
4 will seal into the hole of bead.
Pore size between one group of ball grooves being correspondingly arranged is the 103%-105% of the sphere diameter of bearing ball 2.
The upper surface of the bearing inner race 1.2 is higher than the upper surface of the bearing outer ring 4.1, under the bearing outer ring 4.1
End face is less than the lower face of the bearing inner race 1.2.
The colloid for further fit sealing is provided with outside obturator 3.
Compared with prior art, the utility model between fixed body and rotor by being respectively welded in swing mechanism
Outer ring, and two total members after welding can be dismounted easily, and rolling element is installed to inner ring, the outer ring of swing mechanism
Afterwards, the reliable swing mechanism of connection can be formed, the function of revolution and bearing is realized, larger load and impact can be born, and
Rotation is flexible, durable；Can be widely used in the universal wheel of various structure and sizes, for replace now it is complicated or
The bearing capacity of universal wheel can be improved in the caster bracket of person's fragility, and impact resistance, rotation are flexible, and service life is long.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this practicality
Novel protection domain.
