Description
Technical field
The utility model relates to the angled type reciprocating-piston compressor that a kind of balance of shaking force is optimized.
Background technique
Existing angled type reciprocating-piston compressor (hereinafter referred to as compressor), its balance of shaking force situation is all the best level reaching and can reach in theory, and namely rotating inertia force and the first order reciprocating inertia force, all obtain complete equilibrium.The first order reciprocating inertia force, refers to the reciprocal inertia force that forcing frequency is identical with compressor rotary speed.Two-stage reciprocating inertia force, refers to that forcing frequency is the reciprocal inertia force of a times of compressor rotary speed.Second order and high-order reciprocal inertia force, because of its value less and balance technology too complicated, generally all do not consider.In compressor, rotating inertia force and the first order reciprocating inertia force, by means of the balancer weight quality on bent axle, can obtain the balance of varying degree.Existing compressor inertia equilibrium of forces the optimum state is---rotating inertia force complete equilibrium, the first order reciprocating inertia force only obtains seventy percent balance.Like this, what about the first order reciprocating inertia force of three one-tenth caused disturbs power, causes the vibration of compressor.This kind of vibration, comprise compressor main body vibration, pressurized gas pipeline, cooling water pipeline, lubricating oil pipeline, instrument and pilot line vibrate, the vibration of foundation, factory vibration, miscellaneous equipment vibration in factory building.Vibration is association noise also, the added value power of the parts of association simultaneously and power loss.
Model utility content
The purpose of this utility model, fail to reach the compressor inertia equilibrium of forces the optimum state that can reach in theory exactly for prior art, namely fail to realize rotating inertia force and the first order reciprocating inertia force all complete equilibriums, and propose the new method implementing balance of shaking force optimization.Make compressor rotating inertia force and the first order reciprocating inertia force all complete equilibriums, thus the parts additional stress, noise etc. that make the vibration of compressor, basis, equipment etc. and bring out thus, all reach minimum degree.
To achieve these goals, the utility model adopts following technological scheme.
The angled type reciprocating-piston compressor that balance of shaking force is optimized, comprise bent axle, described bent axle comprises main journal, crank and crank pin; Described main journal is connected with crank by circular cone, and described crank is provided with balancer weight away from main journal side, and described balancer weight exceeds crank in nearly main bearing side, thus the physical dimension of balancer weight and quality is all obtained increase considerably.
Described compressor is V-type, W type or inverted T shape compressor.
Improvement of the present utility model is, the balancer weight of bent axle, surmounts crankshaft handle plane and close to main bearing in nearly main bearing side, and the main journal of bent axle is connected by the circular cone of large-size and crank.
The beneficial effects of the utility model are, the utility model makes the physical dimension of balancer weight and quality all obtain to increase considerably, meet the balancer weight quality needed for balance of shaking force the optimum state (rotating inertia force and the first order reciprocating inertia force all complete equilibriums) that compressor can reach in theory.The utility model is while acquisition balance of shaking force the optimum state, and the intensity of bent axle, stiff super, vibration, noise etc. are all down to minimum, realize sledge and fill compressor bank and be floated on ground oepration at full load and but do not see vibration.

Embodiment
Below in conjunction with drawings and Examples, set forth the utility model further.In the following detailed description, the mode only by illustrating describes some one exemplary embodiment of the present utility model.Undoubtedly, those of ordinary skill in the art can recognize, when not departing from spirit and scope of the present utility model, can revise by various different mode to described embodiment.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.
Existing compressor, the abatement of its inertial force be the quality of the balancer weight 4 at crank 2 place by means of bent axle, and balancer weight 4 is at the centerline direction of bent axle, does not exceed the plane of crank 2 both sides, and the main journal 1 of bent axle is directly connected with crank 2, as shown in Figure 1.
As shown in Figure 2, the angled type reciprocating-piston compressor of the balance of shaking force optimization of the present embodiment, comprise bent axle, described bent axle comprises main journal 1, crank 2 and crank pin 3; Described main journal 1 is connected with crank 2 by circular cone 5, and described crank 2 is provided with balancer weight 4 away from main journal 1 side, and described balancer weight 4 exceeds crank 2 plane in nearly main bearing side, thus the physical dimension of balancer weight 4 and quality is all obtained increase considerably.
The utility model indication compressor, comprises V-type, W type and inverted T shape compressor, and the angled relationships of its each row centreline space is specific, respectively as in Figure 3-5.V-type compressor, the
row cylinder centerline and
the angle of row cylinder centerline is 90 °, W type compressor, the
row cylinder centerline and
the angle, of row cylinder centerline
row cylinder centerline and
the angle of row cylinder centerline is 60 °, inverted T shape compressor, the
row cylinder centerline and
the angle, of row cylinder centerline
row cylinder centerline and
the angle of row cylinder centerline is 90 °.
The utility model changes bent axle in the past, and its balancer weight 4, in crankshaft axis direction, does not exceed the design of the plane of crank 2 both sides.But main journal 1 is connected by the circular cone 5 of large-size and crank 2, balancer weight 4 is made to surmount crank 2 plane in nearly main bearing side and close to main bearing, thus the physical dimension of balancer weight 4 and quality are all obtained increase considerably, to meet under the prerequisite meeting each row centerlines relation shown in Fig. 3-5, reach balancer weight 4 quality all needed for complete equilibrium by rotating inertia force and the first order reciprocating inertia force in theory.Meanwhile, the intensity of bent axle and stiff super.
For reaching the utility model by the object of compressor rotating inertia force and the first order reciprocating inertia force all complete equilibrium, each row reciprocating mass also must meet the following conditions:
A.V type and W type compressor, its each row reciprocating mass equal;
B. inverted T shape compressor, of its horizontal arrangement
row and the
row reciprocating mass is equal, and vertical
row reciprocating mass, be arranged horizontally
row (or the
row) 2 times.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
