Abstract
The invention discloses a plastic hub vacuum coating technology for a baby carriage. The plastic hub vacuum coating technology comprises a wheel housing, a wheel core which is in clamping connection to the wheel housing and can rotate around the wheel housing, and a roller mounted on the wheel core through a rotating shaft. According to the plastic hub vacuum coating technology for the baby carriage, disclosed by the invention, the contact area of the roller and the ground is large, so that high stability is realized, the centre of gravity is low, torque is small, working is reliable, the structure is simple, and the processing and assembling are convenient.
Description
Technical field
The present invention relates to castor, be especially arranged on the plastic wheel hub technique for vacuum coating needing the perambulator under the equipment of frequent shift position.
Background technology
Castor is the conventional refrigerator of thing, such as household electrical appliance, washing machine, the utility cart of hotel's food delivery, and the swivel chair of domestic etc. is required to use, after installing the plastic wheel hub technique for vacuum coating of perambulator, mobile convenient.
The plastic wheel hub technique for vacuum coating of common perambulator is generally divided into two big modules, steering module and roller module.The former make castor can 360 ° rotate, make mobile device can turn to any direction without a hitch；The latter makes mobile device to move freely.Prior art castor center of gravity is higher, and wheel seat is amesiality, and therefore Moment is relatively big, is easily damaged；Structure is loaded down with trivial details, needs assembly many, and such as rotating shaft needs nut to fix, and annexation is the most complicated, and processing increases therewith with assembly process, the most relatively costly.
Summary of the invention
The invention provides a kind of center of gravity low, structure is very simple, the plastic wheel hub technique for vacuum coating of the perambulator that reliability is high.
The present invention provides following technical scheme:
A kind of plastic wheel hub technique for vacuum coating of perambulator, it is applicable to various mobile device, it includes hub, is connected in hub the core wheel that can rotate around hub, and it is eccentrically mounted in the roller of core wheel by rotating shaft, ball is set between hub and core wheel, and can be with coating lubricating oil, to help rotating against of hub and core wheel.
The centrally disposed card article of described hub, described card article end is provided with projection, and described card article stretches into the centre bore of described core wheel, and described projection is stuck on the inner bottom surface of described core wheel, and described core wheel is connected in described hub.Making owing to described hub and core wheel are plastics, therefore access section friction is less, does not affect both and rotates against.
The inner bottom surface of described hub respectively has, with the outer bottom of described core wheel, the annular groove that position is corresponding, arranges ball in described chute.Ball is steel ball, and its quantity and size take the circumstances into consideration to arrange.
The inner bottom surface of described core wheel arranges eccentric draw-in groove, and described rotating shaft snaps in the draw-in groove on described core wheel through the centre bore of described roller.Described rotating shaft is steel, and the friction of the roller made with plastics is less, does not affect the rolling of roller.
Described hub is more than height, in flat with the diameter of described core wheel.The plastic wheel hub technique for vacuum coating device center of gravity of the most whole perambulator is relatively low.
Described roller is the cylinder with centre bore, and length is more than diameter, and therefore roller and ground are linear contact lay, and stress is more uniformly distributed.
The described little body of card notch is big, and oral area is slightly less than shaft diameter, and body portion is slightly larger than roller bearing diameter, will not self falling after therefore rotating shaft snaps in draw-in groove.
Described hub is provided with centre bore, and the support of mobile device can stretch into described centre bore, is coupled together with mobile device by the plastic wheel hub technique for vacuum coating of the perambulator of the present invention.Can not also possess centre bore, for example with bonding or any suitable mode, the plastic wheel hub technique for vacuum coating of the perambulator of the present invention be coupled together with mobile device.
The plastic wheel hub technique for vacuum coating of the perambulator of the present invention, its roller is relatively big with the contact area on ground, the most relatively stable；Center of gravity is relatively low, and Moment is less, therefore reliable operation；And simple in construction, process and assemble is very convenient, and therefore cost is relatively low.

Detailed description of the invention
Accompanying drawings detailed description of the invention.
A kind of plastic wheel hub technique for vacuum coating of perambulator, it is applicable to various mobile device, it includes hub 1, is connected in hub 1 core wheel 2 that can rotate around hub 1, and it is eccentrically mounted in the roller 4 of core wheel 2 by rotating shaft 3, ball 5 is set between hub 1 and core wheel 2, and can be with coating lubricating oil, to help rotating against of hub 1 and core wheel 2.The described centrally disposed card article of hub 1 12, described card article 12 end is provided with protruding 121, and described card article 12 stretches into the centre bore 27 of described core wheel 2, and described protruding 121 are stuck on the inner bottom surface 24 of described core wheel 2, and described core wheel 2 is connected in described hub 1.The inner bottom surface 13 of described hub 1 respectively has annular groove corresponding to position 131 and 231 with the outer bottom 23 of described core wheel 2, arranges ball 5 in described chute 131 and 231.Ball 5 is steel ball, and its quantity and size take the circumstances into consideration to arrange.
The inner bottom surface 24 of described core wheel 2 arranges eccentric draw-in groove 22, and described rotating shaft 3 snaps in the draw-in groove 22 on described core wheel 2 through the centre bore 42 of described roller 4.Described hub 1 is more than height, in flat with the diameter of described core wheel 2.Roller body 41 profile of described roller 4 is cylindrical, is provided with centre bore 42, and the length of roller body 41 is more than diameter.
