Abstract

The utility model discloses a machining-free oily bearing bracket which comprises a bracket body and an oily bearing. A bearing chamber is arranged on the bracket body. The oily bearing and the bearing chamber are in clearance fit connection. The exterior of the oily bearing and the bracket are in interference fit connection through a pressing ring. According to the utility model, the structure is simple and reliable; the oily bearing component is directly assembled without processing; the cost is low; the sizes of the bearing chamber, a rabbit and the like do not need processing, which saves the processing cost and turnover; the precision is high; directly through mould and die casting, the form and position tolerance of the bearing chamber and the cooperation rabbit is ensured; disqualification and waste, which are caused by processing, can be reduced; and a motor has the advantages of stable performance and great consistency.

Description

Exempt to process the oiliness bearing support

Technical field

The utility model relates to field of motor manufacturing, particularly relates to a kind of oiliness bearing support of exempting to process.

Background technology

Series excited machine is widely used in various electric tools, dust catcher, various occasions such as household electrical appliance; Oiliness bearing is a kind of lower cost solution that is used for substituting ball bearing.

For a long time all with the cooperation place of oiliness bearing electric machine support (aluminium alloy) all by the moulding of high precision numerical control machined into, and to be that benchmark is processed other positioning spigot and benchmark with the bearing chamber bearing of sphere, difficulty of processing is big, and waste time and energy, be the technical bottleneck of this lower cost solution always.

The utility model content

The technical problem that the utility model mainly solves provides a kind of oiliness bearing support of exempting to process, can directly guarantee the precision of bearing chamber with mould and design, and the form and position tolerance of bearing chamber and positioning spigot etc., accomplish real exempting from processing and reach design accuracy and instructions for use.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of oiliness bearing support of exempting to process is provided, comprise: rack body, oiliness bearing, offer bearing chamber on the described rack body, matched in clearance is connected between described oiliness bearing and the bearing chamber, and described oiliness bearing is outside to be connected with the support interference fit by a trim ring.

In preferred embodiment of the utility model, be provided with wool felt between described oiliness bearing outside and the trim ring.

In preferred embodiment of the utility model, described wool felt is the wool felt of immersion oil.

In preferred embodiment of the utility model, also fixedly connected by riveting between described trim ring and the support.

The beneficial effects of the utility model are: it is simple and reliable that the utility model exempts to process the oiliness bearing supporting structure, need not to process direct assembling oiliness bearing parts; Cost is low, and oiliness bearing chamber and seam equidimension all need not processing, save processing charges and turnover; Precision is higher, directly guarantees bearing chamber and the form and position tolerance that cooperates seam by mould and die cast, minimizing by processing cause defective with scrap, make motor performance more stable, consistency is better.

Description of drawings

Fig. 1 is the structural representation that the utility model exempts to process one preferred embodiment of oiliness bearing support;

The mark of each parts is as follows in the accompanying drawing: 1, rack body, 2, oiliness bearing, 3, bearing chamber, 4, trim ring, 5, wool felt.

Embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.

See also Fig. 1, the utility model embodiment comprises:

A kind ofly exempt to process the oiliness bearing support, comprising: rack body 1, oiliness bearing 2.

Offer bearing chamber 3 on the described rack body 1, matched in clearance is connected between described oiliness bearing 2 and the bearing chamber 3, and described oiliness bearing 2 is outside to be connected with the support interference fit by trim rings 4.

Cooperate and high-precision aluminium die casting by structural design and size, directly guarantee the precision of bearing chamber 3 with mould and design, and the form and position tolerance of bearing chamber 3 and positioning spigot etc., real exempting from processing and reach design accuracy and instructions for use accomplished.

Be provided with wool felt 5 between described oiliness bearing 2 outsides and the trim ring 4.Described wool felt 5 is the wool felt 5 of immersion oil.

Also fixedly connected by riveting between described trim ring 4 and the support, prevent from getting loose.

It is simple and reliable that the utility model exempts to process the oiliness bearing supporting structure, need not to process direct assembling oiliness bearing 2 parts; Cost is low, and bearing chamber 3 and seam equidimension all need not processing, save processing charges and turnover; Precision is higher, directly guarantees bearing chamber 3 and the form and position tolerance that cooperates seam by mould and die cast, minimizing by processing cause defective with scrap, make motor performance more stable, consistency is better.

The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.

Claims

1. exempt to process the oiliness bearing support for one kind, it is characterized in that, comprising: rack body, oiliness bearing offer bearing chamber on the described rack body, matched in clearance is connected between described oiliness bearing and the bearing chamber, and described oiliness bearing is outside to be connected with the support interference fit by a trim ring.

2. according to claim 1ly exempt to process the oiliness bearing support, it is characterized in that, be provided with wool felt between described oiliness bearing outside and the trim ring.
