Slot, above-mentioned shielding part lower end are embedded in groove.
Such structure can cover precision ball bearings completely, and impurity is avoided to enter at precision ball bearings.
Certainly, groove can also stablize shield lower end of the inside, avoid generating ratio between shield lower end and plate body two
Larger gap.
In the above-mentioned steering wheel group with precision ball bearings, the shield is rubber material.
Shield is flexible rubber material.
In the above-mentioned steering wheel group with precision ball bearings, the quantity of the connection sheet is set for two and symmetrically
In two lower part of plate body, above-mentioned rollers are connected between two connection sheets.
In the above-mentioned steering wheel group with precision ball bearings, the connection sheet is an integral structure with plate body two.
In the above-mentioned steering wheel group with precision ball bearings, the shield is connected in by glue on plate body one.
There is the importing seamlessly transitted in the above-mentioned steering wheel group with precision ball bearings, at the port of the groove
Portion.
In the above-mentioned steering wheel group with precision ball bearings, the introduction part is the fillet at groove port.
In the above-mentioned steering wheel group with precision ball bearings, the introduction part is the chamfering at groove port.
The setting of introduction part can make that shield lower end stablizes embedded in groove.
Compared with prior art, this steering wheel group with precision ball bearings is due to complete by precision ball bearings by shield
It covers entirely, effectively impurity can be avoided to enter at precision ball bearings, therefore, stability is higher.
Simultaneously as precision ball bearings are covered completely by shield, therefore, structure is also compact, has very high
Practical value.
