Abstract
The utility model relates to a bearing floating mounting structure, which comprises an end cover and a bearing base. The bearing base is provided with a bearing mounting hole and a positioning claw, the end cover is equipped with a positioning hole corresponding to the positioning claw, and after the positioning claw and the positioning hole are fittingly mounted, a clearance along a radiating direction of a bearing is formed. After the positioning claw and the positioning hole are engaged, the clearance along the radial direction of the bearing is formed, and the bearing at one end of equipment which is floated can realize automatic alignment, thereby guaranteeing fine straightness and coaxiality between axles of a front bearing and a rear bearing, and reducing friction force among the front bearing, the rear bearing and a shaft. Therefore, the bearing floating mounting structure can be started and operated by low power, and then power of a motor can be reduced greatly.
Description
Technical field
The utility model relates to a kind of bearing floating mounting structure.
Background technique
Prior motor, motor, in the equipment such as water pump, be used to install rotor before, rear bearing all is hard-wired, after rotor is packed into, because the existence of bearing machining error and assembly error, before, be difficult to protect just well straightness accuracy and coaxality between the rear bearing axle, cause bearing to have bigger surface friction drag, make equipment in running, just need more wattless power and produce, both electric efficiency was not high, energy consumption is big, simultaneously because before, be difficult between the rear bearing axle guarantee good straightness accuracy and coaxality, the wearing and tearing of bearing and axle are accelerated, so just increased maintenance cost, product actual life is reduced.
The model utility content
The utility model has overcome above-mentioned shortcoming, and a kind of bearing floating mounting structure that can automatic capturing is provided.
The technical scheme in the invention for solving the technical problem is: a kind of bearing floating mounting structure, comprise end cap and bearing support, described bearing support has bearing mounting hole, described bearing support is provided with positioning pawl, described end cap is provided with and described positioning pawl corresponding positioning hole, described positioning pawl cooperates installation with positioning hole after, have along the gap of bearing radial direction.
Described positioning pawl be with the coaxial same circumference of bearing mounting hole on equally distributed at least two, corresponding, described positioning hole be with the coaxial same circumference of bearing mounting hole on equally distributed at least two.
The front end of described positioning pawl is provided with barb.
Described positioning pawl and positioning hole are respectively four.
After the utility model adopts positioning pawl and positioning hole cooperates, there is the gap along the bearing radial direction, one step bearing of equipment is floated, can realize automatic capturing, good straightness accuracy and coaxality between the forward and backward bearing shaft have so just just been protected, make forward and backward bearing and the axle between friction reduce, very little power just can start and work, power of motor has reduced a lot.Since forward and backward bearing respectively with forward and backward bearing support between cooperation contact by line and becomes face contact, so wear resistance well improved, carry greatly and do working life, need not safeguard and clean, user cost is reduction greatly also.
Description of drawings
Fig. 1 is a decomposition texture schematic representation of the present utility model;
Fig. 2 is a package assembly sectional view of the present utility model.
Embodiment
Mounting structure with condenser type motor and water pump fore bearing is an example below, and the utility model is described in detail.
As shown in Fig. 1,2, the utility model comprises end cap and bearing support, corresponding in the present embodiment being front end gland 2 and front-end bearing pedestal 3, have on the described front-end bearing pedestal 3 and be used for bearings mounted bearing mounting hole (figure indicates), described front-end bearing pedestal 3 is provided with positioning pawl 31, described front end gland 22 is provided with and described positioning pawl 31 corresponding positioning hole 21, described positioning pawl 31 be with the coaxial same circumference of bearing mounting hole on equally distributed four, accordingly, described positioning hole be with the coaxial same circumference of bearing mounting hole on equally distributed four.Described positioning pawl 31 cooperates installation with positioning hole 21 after, has gap 23 along the bearing radial direction.The front end of described positioning pawl 31 is provided with barb 32.
During installation, earlier fore bearing 4 is embedded in the front-end bearing pedestal 3, then front-end bearing pedestal 3 is pressed in the front end gland 2, has the gap, make front-end bearing pedestal 3 and front end gland 2 can relatively move diametrically along the bearing radial direction, constitute floating bearing, thereby realize the automatic capturing of bearing, so just guaranteed between the forward and backward bearing shaft well straightness accuracy and coaxality, make forward and backward bearing with spool between friction reduce, very little power just can start and work, and power of motor has reduced a lot.Described positioning hole 21 is coaxial setting with positioning pawl 31, and positioning pawl 31 front ends have back-off 32, positioning pawl 31 is inserted positioning holes 21 after, can make front-end bearing pedestal 3 hold front end gland 2 tightly and can not come off.
The utility model is easy to assembly, and the component precision requirement is low, so cost is relatively low, because the assurance of coaxality and straightness accuracy, makes that friction reduces between motor shaft and the cover, and merit is decreased reduction.Reduce maintenance frequency, product is increased working life.
More than bearing floating mounting structure provided by the utility model is described in detail, used specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
