Abstract
The invention discloses a bearing component and a manufacturing method thereof. The bearing component comprises a ring and a bearing, wherein the bearing is positioned in the ring; the bearing and the ring are arranged in a concentric manner; and a layer of damping material is arranged between the bearing and the ring. The bearing component with the structure can support the transmission shaft of a balancing machine, and when the ring vibrates due to the unbalance of a rotating workpiece, the damping material between the ring and the bearing absorbs and damps certain vibration to reduce the impact of the ring on the bearing and consequently reduce the vibration amplitude of the transmission shaft on the bearing. Thus, the rotation and measurement of the balancing machine are more stable and reliable.
Description
Technical field
The present invention relates to a kind of bearing, particularly a kind of be used on the balancing machine transmission shaft bearing unit with and production method.
Background technique
Balancing machine is to be used for size and the special device of phase place of rotational workpieces (rotor) unbalancing value of measurement mechanical.According to the dynamic balancing machine measurement result amount of unbalance of rotor is proofreaied and correct, vibration that produces when making the rotor rotation or the vibration that acts on the bearing reduce in the scope of permission, to reach the purpose that reduces vibration, improves performance and improve the quality of products.Balancing machine in use influences the transmission shaft work of balancing machine sometimes because the unbalancing value of the rotational workpieces of test is big, make the transmission shaft of balancing machine produce vibration.If the vibration amplitude of balancing machine transmission shaft is excessive, then might have influence on the balancing machine maintainability, make balancing machine inaccurate to rotational workpieces unbalancing value measurement structure.
Summary of the invention
Deficiency to above-mentioned existing technology; The bearing unit that technical problem to be solved by this invention provides a kind of new structure with and production method; This bearing unit can reduce by the caused transmission shaft vibration amplitude of amount of unbalance effectively, and it is more steadily reliable that the balancing machine running is measured.
For solving the problems of the technologies described above, the present invention adopts following technological scheme:
A kind of bearing unit comprises a lasso and a bearing, and said bearing is positioned at said lasso, and said bearing and said lasso are provided with one heart, is provided with one deck damping material between said radial bearing and the said lasso.
Preferably, said bearing is a radial ball bearing.
A kind of method of making above-mentioned bearing unit, its step comprises:
A lasso and a bearing are provided, and the internal diameter of said lasso is greater than the external diameter of said bearing, and said lasso and said bearing are put with one heart;
Pour into a mould polymer binder in the space between said lasso and said bearing;
Said polymer binder is solidified.
Preferably, said polymer binder by 101 glue and polyurethane binding agent by weight being to form at 5: 1.
Preferably, said polymer binder also contains an amount of ethyl acetate.
Preferably, it is to realize that through a frock said frock is provided with a circular groove that said lasso and said bearing are put with one heart, and the internal diameter of said circular groove equates basically that with the internal diameter of said bearing the external diameter of said circular groove equates with the external diameter of said lasso basically.
Preferably, said frock bottom is provided with aperture, and said aperture is communicated with said circular groove, and the bearing unit that said polymer binder solidifies back formation can take out from said frock through said aperture.
Beneficial effect of the present invention is: the transmission shaft that adopts the bearing unit balance support machine of this structure; When the amount of unbalance of rotational workpieces causes the lasso vibration; Damping material between lasso and the bearing can have and must absorb and cushion vibration; Lasso is reduced the impact of bearing, and then make the transmission shaft amplitude on the bearing reduce, can guarantee that therefore balancing machine running measurement is more steadily reliable.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the structural representation of frock in the embodiment of the invention method.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are carried out detailed introduction:
See also Fig. 1, this bearing unit comprises a radial ball bearing 1 and a lasso 2, and radial ball bearing 1 is positioned at lasso 2, and radial ball bearing 1 is provided with lasso 2 with one heart, is provided with one deck damping material 3 between radial ball bearing 1 and the lasso 2.
The manufacturing step of above-mentioned bearing unit comprises: a lasso 2 and a radial ball bearing 1 at first are provided, and the internal diameter of lasso 2 is placed on lasso 2 and radial ball bearing 1 in the special frock 4 greater than the external diameter of radial ball bearing 1 then.See also Fig. 2, frock 4 is provided with a circular groove 5, and the internal diameter of circular groove 5 equates basically that with the internal diameter of radial ball bearing 1 external diameter of circular groove 5 equates basically that with the external diameter of lasso 2 bottom of frock 4 is provided with aperture 6, and aperture 6 is communicated with circular groove 5.With radial ball bearing 1; Lasso 2 is put into circular groove 5; A kind of polymer binder of cast in the space between lasso 2 and radial ball bearing 1; This polymer binder includes anchor 101 glue, polyurethane binding agent and an amount of ethyl acetate, and wherein the weight ratio of anchor 101 glue and polyurethane binding agent is 5: 1.After pouring, wipe the polymer binder that overflows with rag, and keep making in 30 hours this polymer binder to solidify at normal temperatures, this polymer binder solidifies the back and forms the vibration damping layer, and available then screw ejects the bearing unit that makes through aperture 6.Use for ease, can process further this bearing unit, as this bearing unit is placed on the external cylindrical grinding machine, the excircle cylindrical grinding to this bearing unit has reached corresponding drawing requirement.
Adopt the transmission shaft of the bearing unit balance support machine of this structure; When the amount of unbalance of rotational workpieces causes lasso 2 vibrations; Damping material 3 between lasso 2 and the radial ball bearing 1 can have and must absorb and cushion vibration; The impact of 2 pairs of radial ball bearings 1 of lasso is reduced, and then make the transmission shaft amplitude on the radial ball bearing 1 reduce, can guarantee that therefore balancing machine running measurement is more steadily reliable.
More than a kind of bearing unit and production method thereof that the embodiment of the invention provided have been carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the embodiment of the invention, the part that on embodiment and application area, all can change, in sum; This description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
