Abstract
A kind of screw compressor built-up crankshaft being easily installed, it includes bent axle（1）, eccentric disc（2）And eccentric shaft（3）, bent axle（1）And eccentric shaft（3）It is separately fixed at eccentric disc（2）Both sides, it is characterized in that described eccentric disc cylindrical on be machined with installation bearing steel ball（4）Raceway, bearing steel ball（4）On outer ring is installed（6）, retainer（5）It is arranged on outer ring（6）And eccentric disc（2）Between make bearing steel ball（4）Move in raceway and form bearing arrangement, so that eccentric disc（2）Integral structure is formed with bearing.Original bent axle and two part designs of base bearing are integral type by this utility model, are reduced the installation step of crankshaft group, have been saved installation time, reduce assembly cost, while alleviating the overall weight of compressor on the premise of holding is durable.
Description
Technical field
This utility model is related to a kind of scroll compressor, especially a kind of crankshaft structure of scroll compressor, specifically
Say it is a kind of screw compressor built-up crankshaft being easily installed in ground.
Background technology
The crankshaft structure of traditional scroll compressor is as shown in figure 1, it is by bent axle 1, eccentric disc 2, eccentric shaft 3, bearing 7
Constitute with balancing disk 8, need first bearing 7 is fixedly mounted on eccentric disc during installation, then eccentric disc is installed before the compressor
Gai Zhong, the bent axle of this structure not only need first to install bearing, and operation is loaded down with trivial details, and the overall weight of bent axle is larger.
Utility model content
It is two individual components for the bent axle and bearing of existing scroll compressor that the purpose of this utility model is, peace
Need first to enter crank eccentric disc in bearing, then by crankshaft installed in fore shell during dress, not only installation steps are more, and bent axle
The problem that overall weight lays particular stress on, designs a kind of screw compressor use being easily installed that bearing and eccentric disc are integrally attached to structure
Built-up crankshaft.
The technical solution of the utility model is：
A kind of screw compressor built-up crankshaft being easily installed, it include bent axle 1, eccentric disc 2 and eccentric shaft 3, bent
Axle 1 and eccentric shaft 3 are separately fixed at the both sides of eccentric disc 2, it is characterized in that described eccentric disc cylindrical on be machined with installation axle
The raceway of steel ball 4 being held, outer ring 6 being installed on bearing steel ball 4, retainer 5 is arranged on and bearing steel is made between outer ring 6 and eccentric disc 2
Ball 4 is moved in raceway and forms bearing arrangement, so that eccentric disc 2 forms integral structure with bearing.
The beneficial effects of the utility model：
Original bent axle and two part designs of base bearing are integral type by this utility model, reduce the dress of crankshaft group
With step, installation time has been saved, assembly cost has been reduced, while the entirety of compressor is alleviated on the premise of holding is durable
Weight, eliminates balancing disk.
Description of the drawings
Fig. 1 is the structural representation of existing bent axle.
Fig. 2 is the structural representation of bent axle of the present utility model.
Fig. 3 position views that are bent axle of the present utility model in 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 screw compressor built-up crankshaft being easily installed, it include bent axle 1, eccentric disc 2 and eccentric shaft 3, bent
Axle 1 and eccentric shaft 3 are separately fixed at the both sides of eccentric disc 2, described eccentric disc cylindrical on be machined with bearing steel ball 4 be installed
Raceway, is provided with outer ring 6 on bearing steel ball 4, retainer 5 is arranged on and makes bearing steel ball 4 between outer ring 6 and eccentric disc 2 in raceway
Interior motion forms bearing arrangement, so that eccentric disc 2 forms integral structure with bearing, as shown in Figure 2.This structure will not
Installation step is reduced, and balancing disk can be saved, so that the overall weight of bent axle is reduced.Bent axle of the present utility model is in compression
In machine, position is as shown in Figure 3.
This utility model is not directed to partly same as the prior art or can be realized using prior art.
