Abstract
A kind of scroll compressor combination type pad eccentric bushing of energy improve mechanical strength, is characterized in that it by eccentric disc（1）And straight pin（2）Composition, described straight pin interference fit are fitted in eccentric disc（1）On pin-and-hole（3）In.This utility model is by being changed to the high intensity straight pin with special process process by the stalklet of original integral type eccentric bushing, stress at this is optimized for straight pin with eccentric bushing contact surface entirety stress by original knuckle stress, stress concentration is reduced, durability is improved.
Description
Technical field
This utility model is related to a kind of screw compressor technology, especially a kind of structure of scroll compressor eccentric bushing,
Specifically a kind of scroll compressor combination type pad eccentric bushing of energy improve mechanical strength.
Background technology
At present, the eccentric shaft 4 on the eccentric bushing of scroll compressor mostly with eccentric bushing be monolithic construction, this structure
When machining is carried out, can there is knuckle 5 in the root of eccentric shaft, this knuckle can produce stress concentration, shadow
The mechanical strength of eccentric shaft is rung, or even off-axis phenomenon occurs, to this at present in addition to reducing knuckle, the solution that there is no
Certainly scheme.
Utility model content
The purpose of this utility model is there is eccentric shaft root bad mechanical strength for existing monoblock type eccentric bushing structure
The problem of easy fracture, designs and a kind of can eliminate stress concentration phenomenon so as to providing the scroll compressor Combined press of mechanical strength
Pin eccentric bushing.
The technical solution of the utility model is：
A kind of scroll compressor combination type pad eccentric bushing of energy improve mechanical strength, is characterized in that it by eccentric disc 1
Constitute with straight pin 2, described straight pin interference fit is fitted in the pin-and-hole 3 on eccentric disc 1.
The length in pin-and-hole on the described insertion eccentric disc 1 of straight pin 2 is not less than the length for exposing eccentric side surface.
The beneficial effects of the utility model：
This utility model is by being changed to the high intensity cylinder with special process process by the stalklet of original integral type eccentric bushing
Stress at this is optimized for straight pin and eccentric bushing contact surface entirety stress by original knuckle stress, is reduced by pin
Stress concentration, improves durability.
Description of the drawings
Fig. 1 is the structural representation of existing eccentric bushing.
Fig. 2 is the structural representation of eccentric bushing of the present utility model.
Fig. 3 is that eccentric bushing of the present utility model acts on schematic diagram within the compressor.
Specific embodiment
With reference to the accompanying drawings and examples this utility model is further described.
As shown in Figure 2.
A kind of scroll compressor combination type pad eccentric bushing of energy improve mechanical strength, it is by eccentric disc 1 and straight pin 2
Composition, described straight pin interference fit are fitted in the pin-and-hole 3 on eccentric disc 1, the pin-and-hole on the insertion eccentric disc 1 of straight pin 2
In length not less than the length of eccentric side surface is exposed, as shown in Figure 2.Eccentric bushing of the present utility model peace within the compressor
Holding position is as shown in Figure 3.This utility model is not only easy to process, and eliminates application concentration, moreover it is possible to mitigate the whole of eccentric disc
Body weight.
This utility model is not directed to partly same as the prior art or can be realized using prior art.
