Description
Technical field
The utility model is related to Castor structure technical fields, specifically, it shows a kind of shock resistance universal wheel.
Background technology
Universal wheel is the common accessory in the equipment such as moving trolley, wherein there is swing mechanism, allows lower part wheel support etc.
Around 360 ° of continuous rotations of the centre of gyration, the direction of travel for changing castor can be coordinated.The steering of existing caster bracket mostly uses rolling
Bead, does raceway respectively on mounting plate and wheel support, on raceway after grease arrangement ball with axis pin by mounting plate and wheel branch
Frame rivets, and swing mechanism is constituted by ball and upper and lower raceway at middle part；Caster bracket not only carry it is small, it is complicated, and
It will appear after long-time use and turn to situations such as clamping stagnation is laborious.
Therefore, it is necessary to provide a kind of shock resistance universal wheel to solve the above problems.
Utility model content
The purpose of this utility model is to provide a kind of shock resistance universal wheel.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of shock resistance universal wheel, including universal wheel mounting plate assembly, universal wheel lower bracket assembly, wheel shaft, wheel assembly, wheel
Axis nut；The universal wheel mounting plate assembly is formed by fixedly connecting by universal wheel mounting plate and bearing inner race, the universal wheel
Lower bracket assembly is formed by fixedly connecting by bearing outer ring and universal wheel lower bracket；It is right between the bearing inner race and the bearing outer ring
It should be provided with several groups pearl slot, bearing ball is provided in one group of corresponding pearl slot.
Further, it is provided on the bearing outer ring and fills out the hole of bead, described fill out in the hole of bead is provided with bearing obturator.
Further, the pore size between pearl slot described in one group be correspondingly arranged is the sphere diameter of the bearing ball
103%-105%.
Further, the further fit sealing of colloid can be added outside the bearing obturator again.
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, steering positioning, universal is provided on the universal wheel mounting plate assembly or universal wheel lower bracket assembly
Wheel brake or shock-damping structure.
Further, several wheel bodys are provided on the wheel assembly.
Compared with prior art, the utility model between the fixed body and rotor of caster bracket by being respectively welded
The Internal and external cycle of swing mechanism, and two total members after welding can be dismounted easily, and rolling element is installed to swing mechanism
Inner ring, behind outer ring, the reliable swing mechanism of connection can be formed, the function of revolution and bearing is realized, larger load can be born
And impact, and rotate flexibly, it is durable.It can be widely used in the equipment such as various loading platforms and moving trolley, have
The advantages that high-mechanic, impact resistance, rotation are flexible, and service life is long.
Description of the drawings
Fig. 1 is one of structural schematic diagram of the embodiments of the present invention.
Fig. 2 is the second structural representation of the embodiments of the present invention.
Specific implementation mode
Embodiment：

Bearing outer ring 4.1 and universal wheel lower bracket 4.2 are formed by fixedly connecting；Several groups are correspondingly arranged between bearing inner race and bearing outer ring
Pearl slot is provided with bearing ball 2 in one group of corresponding pearl slot.
It is provided on bearing outer ring and fills out the hole of bead, filled out in the hole of bead and be provided with bearing obturator 3.
3 outside of bearing obturator can add the further fit sealing of colloid again.
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.
It is provided with steering positioning, universal wheel brake on universal wheel mounting plate assembly 1 or universal wheel lower bracket assembly 4 or subtracts
Shake structure.
Several wheel bodys are provided on wheel assembly 6.
Bearing ball 2 between device enters the gap between group pearl slot one by one, is waited after being attached to suitable quantity, with obturator 4
It will be sealed into the hole of bead.
Pore size between one group of pearl slot being correspondingly arranged is the 103%-105% of the sphere diameter of bearing ball 2.
Compared with prior art, the utility model between the fixed body and rotor of caster bracket by being respectively welded
The Internal and external cycle of swing mechanism, and two total members after welding can be dismounted easily, and rolling element is installed to swing mechanism
Inner ring, behind outer ring, the reliable swing mechanism of connection can be formed, the function of revolution and bearing is realized, larger load can be born
And impact, and rotate flexibly, it is durable.It can be widely used in the equipment such as various loading platforms and moving trolley, have
The advantages that high-mechanic, impact resistance, rotation are flexible, and service life is long.
The above are merely some embodiments of the utility model.For those of ordinary skill in the art, not
Under the premise of being detached from the concept of the present invention, various modifications and improvements can be made, these belong to the utility model
Protection domain.
