Abstract
Self regulating shock rubber parts, comprises cylindrical, through hole, it is characterized in that: described cylindrical more intermediate annular is provided with rectangular recess, is provided with annular boss between cylindrical and rectangular recess; Described through hole two ends are provided with conical bore, and through hole two ends and conical bore intersection are provided with annular muscle.The utility model is simple and reasonable, makes motor position free adjustment among a small circle, thus makes mounting position of motor reasonable, reduces the vibration of motor, reduces the generation of the bad noise of air-conditioning.
Description
Technical field
The utility model relates to vibration isolation rubber structure, particularly relates to a kind of Self regulating shock rubber parts for ceiling type central air-conditioning air supply motor.
Background technology
Air-conditioning motor, when being installed on air-conditioning, can use rubber parts between, and object reduces motor oscillating.Due to motor, this has electric and magnetic oscillation and mechanical oscillation generation in operation process, is generically and collectively referred to as motor oscillating.Motor oscillating can be delivered on air-conditioning by installation foot, and because the mounting panel material of air-conditioning is steel plate, steel plate can amplify the vibration of motor, and in operation of air conditioner process, these vibrations will produce abnormal sound.The rubber parts used between the two can slow down motor oscillating, plays buffering obstruct motor oscillating and is delivered on air-conditioning.Rubber parts generally makes cylindrical shape, circumferentially slots in the middle part of external cylindrical surface, and motor installation foot is stuck in groove, and such rubber parts is arranged on motor by this groove.Be provided with through hole in the inside of rubber parts, bolt couples together motor and air-conditioning through this through hole.The weight of general central air-conditioning motor is large, needs the thickness increasing damping ring just can reach the object of slowing down vibration.Which adds the length that bolt coordinates with rubber parts, a motor generally uses 3 ~ 4 rubber parts, uniform at circumferencial direction, when motor is installed, is difficult to ensure coordinating all in desirable state of all rubber parts and screw.When motor installation site slightly deviation time, easily stuck between bolt and rubber parts, there is the problems such as motor inclination, make air-conditioning fan operate uneven and produce noise.
Summary of the invention
The purpose of this utility model aims to provide a kind of vibration isolation rubber part, motor position free adjustment among a small circle can be made, thus make mounting position of motor reasonable, reduce the generation of the bad noise of air-conditioning, can be good at the vibration reducing motor, overcome weak point of the prior art.
The utility model patent is achieved in that Self regulating shock rubber parts, comprises cylindrical, through hole, it is characterized in that: described cylindrical more intermediate annular is provided with rectangular recess, is provided with annular boss between cylindrical and rectangular recess; Described through hole two ends are provided with conical bore, and through hole two ends and conical bore intersection are provided with annular muscle.
Described annular muscle is set to semicircle shape, and radius is R0.5 ~ 1mm.
Width 0.8 ~ the 1.2mm larger than the thickness of motor installation foot of described rectangular recess.
The width 1mm larger than the thickness of motor installation foot of described rectangular recess.
The utility model is simple and reasonable, makes motor position free adjustment among a small circle, thus makes mounting position of motor reasonable, reduces the vibration of motor, reduces the generation of the bad noise of air-conditioning.

In figure 1, rectangular recess, 2, annular boss, 3, through hole, 4, conical bore, 5, annular muscle, 6, cylindrical.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
With reference to accompanying drawing, Self regulating shock rubber parts, comprises cylindrical 6, through hole 3, it is characterized in that: described cylindrical 6 more intermediate annular is provided with rectangular recess 1, is provided with annular boss 2 between cylindrical 6 and rectangular recess 1; Described through hole 3 two ends are provided with conical bore 4, and through hole 3 two ends and conical bore 4 intersection are provided with annular muscle 5.Described annular muscle 5 is set to semicircle shape, and radius is R0.5 ~ 1mm.Width 0.8 ~ the 1.2mm larger than the thickness of motor installation foot of described rectangular recess 1.The width 1mm larger than the thickness of motor installation foot of described rectangular recess 1.
During concrete enforcement, Self regulating shock rubber parts entirety sees it is cylindrical, be used for matching with motor installation foot in the middle recessing of external cylindrical surface, annular boss is designed in the top and bottom of groove, object is the contact area both having increased vibration isolation rubber part and motor, noncontact face portion additionally reduces the wall thickness of vibration isolation rubber part, and wall thickness reduces the elasticity that can increase vibration isolation rubber part.Matched in clearance between vibration isolation rubber part and motor installation foot, double-faced clearance can adopt 0.8mm or 0.9mm or 1mm or 1.1mm or 1.2mm, object be vibration isolation rubber part with motor installation foot coordinate the surplus leaving automatic position adjusting function, when uniform 3 ~ 4 the vibration isolation rubber part installation sites of motor circumferencial direction slightly deviation time, motor position automatically can regulate and make the elasticity of vibration isolation rubber part be in best state, there will not be stuck between vibration isolation rubber part and motor installation foot and make vibration isolation rubber part be extruded elasticity by transition to be deteriorated, thus air conditioner noises is increased.The indoor design of vibration isolation rubber part has through hole and screw fit, is designed to cone hole at the two ends of through hole, with the length of reduce orifice and screw fit.Through hole and conical bore intersection, be designed with the annular muscle of radius R 0.5 ~ 1mm, namely an annular muscle is respectively had at the through hole two ends with screw fit, it is matched in clearance between screw and vibration isolation rubber part, the object of such design allows coordinating of screw and endoporus can automatic position adjusting function state, namely screw has certain adjustment surplus in vibration isolation rubber part, like this when circumferencial direction 3 ~ 4 vibration isolation rubber parts of a motor are installed, and can not because of position slightly deviation and occur stuck phenomenon.By the process of above vibration isolation rubber part endoporus and cylindrical, ensure that motor is arranged on after on air-conditioning, motor position can in operation process automatic capturing, reduce the vibration passing of motor on air-conditioning, and then effectively avoid the generation of air-conditioning resonance noise.
