Abstract

The utility model discloses an automatic centering sliding bearing of ceiling fans which is arranged on the head of a ceiling fan, comprising a bearing lining 1, a casing 2, a clamp spring 3, and an oil storage chamber. The utility model can automatically adjust the center of an axle hole and reduce the requirements of the machining accuracy and the installation accuracy of a motor shaft. Compared with the bearing of the traditional ceiling fan motor, the utility model has the advantages that the cost is reduced, the machine installing efficiency is improved, the noise is reduced, and the operational reliability improved.

Description

A kind of ceiling fan self-aligning bearing

The utility model relates to a kind of bearing, is a kind of self-aligning sliding bearing that is installed on the ceiling fan head specifically.

The bearing of ceiling-fan motor is a strength member.Present ceiling-fan motor all uses traditional ball bearing basically, this bearing cost height, and noise is big.Part producer once tried out the powder metallurgy oil-impregnated bearing of ring in recent years, but center, the bearing of ring non-adjustable bearing hole, therefore the machining accuracy to motor shaft requires very high, very inconvenient during installation, and functional reliability is poor, in case voltage is lower than voltage rating, starting is just very slow, even can't start.

The bearing sleeve that a kind of sphere was arranged on desk fan, but there is not special shell supporting with it, but directly match with support, make manufacturing, install and keep in repair all cumbersome.

The purpose of this utility model is that the bearing to ceiling-fan motor is improved, and the central shaft hole of bearing can be adjusted automatically, thereby reduces production costs, improves efficiency of installing software, reduces noise, strengthens functional reliability, prolongs the ceiling fan life-span.

For achieving the above object, the scheme that the utility model proposes is: but ball bearing that ceiling-fan motor is original or annular oil-impregnated bearing change the spherical bearing of self-aligning into, and this spherical bearing is made up of bearing sleeve 1, shell 2, jump ring 3 and oil storage storehouse.Bearing sleeve 1 and shell 2 cooperate for sphere, in the end face of shell 2 concave surface are arranged, in put jump ring, to finish the function of self-aligning.Also have an oil storage storehouse below the jump ring, play lubricating bearings.

The advantage of this bearing is: 1. cost is low, compares with the ball bearing that ceiling fan is commonly used, and cost reduces by 40%～70%, and processing and also greatly reduction of installation precision requirement to motor shaft have improved efficiency of installing software; 2. noise is little; 3. strengthened functional reliability, move 5000 hours continuously after, use the 40V voltage starting again, still meet start request fully.

Further specify below in conjunction with drawings and Examples.

Fig. 1 is the erection drawing of self-aligning spherical bearing.

Fig. 2 is the structural drawing of bearing sleeve.

Fig. 3 is the structural drawing of shell.

Fig. 4, Fig. 5 are the structural drawing of jump ring.

Embodiment as shown in Figure 1, bearing is assembled by shown position successively by bearing sleeve 1, shell 2, jump ring 3 and malthoid 4, wherein bearing sleeve 1 and shell 2 fuse by modes such as punching presses before being installed to ceiling-fan motor, so very convenient when installing.Jump ring 3 is positioned at one of the shell 2 end faces circular concave surface with the shell coaxial line, and jump ring has 8～16 knuckle-tooth v notch vs and same number of reed, and outstanding reed all curves certain radian to cooperate with the bearing sleeve of sphere.Also have a concave surface that radius is a little bit smaller slightly in the jump ring bottom, inside is placed with the malthoid of an annular, forms an oil storage storehouse, plays lubricating bearings when bearing rotates.

In each part of bearing, the material of jump ring is 65Mn, and the material of shell is the Fe-C alloy then, and processes by powder metallurgical technique.

Claims

1. self-aligning sliding bearing that is installed on the ceiling fan head, form by bearing sleeve 1, shell 2, jump ring 3 and oil storage storehouse, it is characterized in that the face that bearing sleeve 1 contacts with shell 2 is that sphere cooperates, jump ring 3 is positioned at the circular concave surface of shell 2 one ends and shell coaxial line, the outstanding reed of jump ring props up bearing sleeve 1 realizing the function of self-aligning, also has an oil storage storehouse below the jump ring.

2. bearing as claimed in claim 1 it is characterized in that a radius slightly little circular concave surface of described oil storage position in storehouse below jump ring 3, and inside is placed with malthoid 4.

3. bearing as claimed in claim 1 is characterized in that jump ring 3 has the crenation breach and the same number of reed of several symmetrical distributions, and outstanding reed all curves certain radian, cooperates with the sphere with bearing sleeve 1.

4. bearing as claimed in claim 1 is characterized in that the material of shell 2 is the Fe-C alloy through powder metallurgical technique processing.
