Embodiment
Describe with reference to the accompanying drawings mode of execution of the present utility model in detail.Wherein, the directional terminology described in literary composition, such as " left side ", " right side ", " on ", D score, for drawing.
Fig. 1 is according to the sectional view of the hermetically sealed compressor of a kind of preferred implementation of the present utility model, shows in using the vibration damping structure of state.Hermetically sealed compressor 1 shown in Fig. 1 comprises: compressor housing 20; Be contained in the compressor movement 30 in compressor housing 20; And be contained in the compressor vibration damping structure 40 that compressor housing 20 inner supports compressor movement 30.Compressor vibration damping structure 40 comprises that according to compressor movement 30 weight distribution in compressor housing 20 sets several Compress Springs of specification.These Compress Springs of setting specification according to the weight distribution of compressor movement 30 are distributed in several corners of compressor movement 30, for supports compressor movement 30, the vibration while simultaneously reducing 30 work of compressor movement is delivered to the energy of compressor housing 20.
In the example embodiment shown in fig. 1, compressor vibration damping structure 40 comprises that according to compressor movement 30 weight distribution in compressor housing 20 sets four Compress Springs of specification.Certainly, it may occur to persons skilled in the art that, the quantity of Compress Spring is not limited to this, can increase and decrease as required.
In one embodiment, for example, at the free height H1 of the Compress Spring 42,43 of the larger wt part (left side in Fig. 1) of described compressor movement 30, be greater than for example, free height H2 at the Compress Spring of being made by identical springs silk 44,45 of the lower weight part (right side in Fig. 1) of described compressor movement, as shown in Figure 2.Liberty height, refers to height value when Compress Spring two ends are not applied in any external force.Like this, although the left side weight of the compressor movement 30 in Fig. 1 example is larger, right side weight is lighter, but because the free height H1 of Compress Spring 42,43 is greater than the free height H2 of Compress Spring 44,45, after assembling, described vibration damping structure still can guarantee the horizontal position of compressor movement.
In this example, if compressor movement 30 acts on Compress Spring 42, gravity on 43 is M1, compressor movement 30 acts on Compress Spring 44, gravity on 45 is M2, Compress Spring 42, 43 overall height, two Compress Springs 42 and 43 free height sum are L1, Compress Spring 44, 45 overall height, two Compress Springs 44 and 45 free height sum are L2, the elasticity coefficient of four Compress Springs is K, Compress Spring 42, 43 and Compress Spring 44, 45 height difference can calculate with formula below: (L1-L2)=and (M1-M2)/(2*K).
Certainly, these four Compress Springs 42,43,44 and 45 free height can be according to the weight distribution of described compressor movement 30 and are all not identical.When supports compressor movement 30, although the each several part weight distribution of compressor movement 30 is different, the height after being compressed is identical with 45 for these Compress Springs 42,43,44, thereby supports reposefully, as shown in Figure 1 like this.
In one embodiment, at the diameter D1 of the spring thread of the Compress Spring of the larger wt part of described compressor movement, be greater than the diameter D2 at the spring thread of the Compress Spring of the identical free height of the lower weight part of described compressor movement, as shown in Figure 3.Like this when supports compressor movement 30, although the each several part weight distribution of compressor movement 30 is different, these Compress Springs 42,43,44 are identical with the height after 45 be compressed, thereby reposefully compressor movement supported.
In one embodiment, in the free height of the Compress Spring of the larger wt part of described compressor movement, be greater than the free height at the Compress Spring of the lower weight part of described compressor movement, and be greater than the diameter at the spring thread of the Compress Spring of the lower weight part of described compressor movement at the diameter of the spring thread of the Compress Spring of the larger wt part of described compressor movement.Like this when supports compressor movement 30, although the each several part weight distribution of compressor movement 30 is different, these Compress Springs 42,43,44 are identical with the height after 45 be compressed, thereby support reposefully.
In one embodiment, in the elasticity coefficient of the Compress Spring of the larger wt part of described compressor movement, be greater than the elasticity coefficient at the Compress Spring of the lower weight part of described compressor movement.Like this when supports compressor movement 30, although the each several part weight distribution of compressor movement 30 is different, these Compress Springs 42,43,44 are identical with the height after 45 be compressed, thereby support reposefully.Wherein the formula of the elastic coefficient is: K=GD/8C3N, wherein: K is the elastic coefficient; G is the shear modulus of spring material; D is spring thread diameter; C is the ratio that curls up of spring; N is the number of active coils of spring.According to the formula of the elastic coefficient, by selecting the spring of different materials, adjust spring thread diameter D, select the elasticity coefficient of adjusting spring than the modes such as number of active coils N of C and spring of curling up of different springs, thereby set the specification of the Compress Spring in vibration damping structure.
The Compress Spring of above-mentioned vibration damping structure is made by material known in the art, and the cross section of making the spring thread of Compress Spring can be suitable shape arbitrarily, and Compress Spring integral body can be any suitable shape.
