Abstract
The utility model discloses an omnibearing elastic support member for a motor bearing, relating to a mechanical component. The utility model aims at providing the omnibearing elastic support member, and a rigidity or part of an elastic supporting mode is replaced by the bearing mode. The omnibearing elastic support member is composed of an inner strutting piece (8) and an outer strutting piece (5), and rings are evenly made of a spring steel band. One side of the ring (1) is provided with a reed (2) which turns down rims in the same direction, and the reep is in an elastic unguiform structure. 3-12 small mouths (3) are arranged between the reed, and the size of inner and the outer strutting pieces can be the same or different. The utility model has strong antivibration ability and aligning ability, and is especially suitable for the motor which has high speed and can bear shock load and high-frequency vibration.
Description
The utility model relates to mechanical parts, furthermore, relates to spring support member.
Generally, the bearing of motor all is to adopt rigidity supporting structure or part elastic support structure.Can normally move for a long time under the situation that these two kinds of structures are lower in motor rotation speed, vibration is less, the operation of bearing " life-span " is also long.Yet when motor speed up to more than the 12000rpm, simultaneously when bearing load, particularly rotating speed and load rapid change, bearing is subjected to be subjected to the influence of motor rotatable parts precision to very big impact in addition, the rotation of bearing " life-span " sharply descends.Sometimes bearing several hrs that can only turn round will damage, and people are forced to change bearing again.This is the consumable part material both, can influence production again.Tracing it to its cause, all is because the rigidity supporting structure or the elastic support structure of bearing cause.And adopt the motor up-to-standard rate of former supporting structure low, can only reach 50% usually.Therefore, for high-speed electric expreess locomotive, must change the supporting structure of bearing.But there are not up to now, the report of comprehensive supporting structure and product to come out as yet.
Purpose of design of the present utility model, just be to provide a kind of comprehensive spring support member of motor bearings, its supporting structure is changed, thereby replace rigid support mode or part elastic support structure, to prolong the use " life-span " of bearing with comprehensive elastic support mode.
For reaching this purpose, the designer is by observing and practice, design the comprehensive spring support member of motor bearings, this member still is made up of an interior supporting element and an outer support member, but they are with having the ring that the favorable elasticity metallic material is made, the i.e. reed of flange radially of oriented same direction on one side of this ring, and reed is designed to the claw type structure, promptly stress and the suitable elasticity of maintenance in order to disperse generation in service has 3～12 osculums between the reed.The size of inside and outside supporting element can be identical, also can be different.
Usually the material of used elastic metallic is a Spring Steel Band.When assembling, interior supporting element is contained in the inside of bearing support, and reed is inside; Laid after the bearing, outer supporting element then is contained in the outside of bearing support, and reed is outside; The bearing that relies on bearing cap will be with felt gasket is clipped in the middle of two supporting elements.
Because comprehensive spring support member has stronger buffer capacity for impulsive load, so it has stronger antivibration ability and aligning ability, is specially adapted to high rotating speed and the motor of withstand shocks load and dither.The comprehensive spring support member that high-revolving motor uses the utility model to provide, its bearing operation " life-span " improves 5～10 times than original bearing; All one's effort position spring support member that the motor of the load that withstands shocks and dither adopts the utility model to provide can guarantee that the up-to-standard rate of motor is higher than the up-to-standard rate of original motor, reaches 98%.
Accompanying drawing 1 is the structural representation of comprehensive spring support member, accompanying drawing 2 be the A-A of accompanying drawing 1 to view, 1 is ring among Fig. 1 and Fig. 2,2 is reed, 3 is osculum; Accompanying drawing 3 is for using the erection drawing of comprehensive spring support member, and 4 is bearing support among the figure, and 5 is outer supporting element, and 6 is bearing, and 7 is felt gasket, and 8 is interior supporting element.
Embodiment: the mowing machine that the U.S. orders goods exchanges series excited machine with HC62 series, rotation speed n＞12000rpm, and its rotating shaft diameter is 8mm; Used D bearing (6) is " Bao Laide " iron-based oil-impregnated bearing, external diameter 15.9mm, internal diameter 8mm.The spring support member that adopts as shown in drawings, the ring that system is made by Spring Steel Band (1), comprise that external diameter is that 21.8mm, thickness are that interior supporting element (8) and the external diameter of 3.2mm is that 22mm, thickness are the outer supporting element (5) of 3.7mm, they respectively have 6 osculums (3) and 6 reeds (2); Interior supporting element is contained in the inside of bearing support, and reed is inside, and outer supporting element then is contained in the outside of bearing support, and reed is outside; The bearing (6) that bearing cap will be with felt gasket (7) is clipped in the middle of inside and outside two supporting elements.Motor up-to-standard rate with this spring support member reaches 98%, and bearing operation " life-span " reaches 80～180h.
Claims (2)
- The comprehensive spring support member of 1 motor bearings, form by an interior supporting element and an outer support member, it is characterized in that this member is the ring (1) that the flexible metallic material of apparatus is made, the reed (2) of oriented same direction flange is the claw type structure on one side of this ring (1); Have 3～12 osculums (3) between the reed (2).
- 2 comprehensive spring support members as claimed in claim 1 is characterized in that described elastic metallic material is a Spring Steel Band.
