Abstract
The invention discloses a kind of constant temperature structure of belt transmission main shaft, including the first transmission main shaft, the second transmission main shaft, belt, casing, the first belt pulley and the second belt pulley；The first belt pulley is installed on first transmission main shaft, the second belt pulley is installed on second transmission main shaft, connected between first belt pulley and the second belt pulley by belt transmission, first belt pulley, the second belt pulley and belt are respectively positioned in casing, air is injected into casing by the way that fan air inlet is lasting during belt transmission, air is quickly moved to exhaust outlet with belt transmission direction, exhaust fan is connect on the outside of air exhaust box to extract air in casing out, while the heat produced during taking away belt transmission.The present invention increases by a casing to belt transmission part, and air is injected into casing, and takes air away by air draft, so that the heat produced during taking away belt transmission, reduction temperature rise influences on main shaft, improves main shaft stable accuracy performance.
Description
Technical field
The invention belongs to mechanical manufacturing field, and in particular to a kind of constant temperature structure of belt transmission main shaft.
Background technology
Main shaft of numerical control machine tool power transmission typically uses belt wheel belt transmission structure, and this structure has easy for installation, transmission
The features such as abnormal impact influences small, but because the heat that belt and belt wheel friction and stress and deformation are produced can make the temperature of drive disk assembly
Quick rise, because temperature rise causes the drive disk assemblies such as main shaft to deform, passes through actual measurement, it has been found that main transmission box is in 30 minutes
2000 temperature changes in the case of speed of walking around reach 10 DEG C.
The main shaft deformation quantity brought by difference variation reaches 0.04mm, the temperature rise speed when machine tool spindle is cut
Faster temperature rise amplitude is bigger, because the deterioration that the deformation band of main shaft carrys out machine finish is easily produced when processing is compared with precision component
Substandard products.
The content of the invention
Goal of the invention：In order to solve the deficiencies in the prior art, the invention provides a kind of constant temperature knot of belt transmission main shaft
Structure.
Technical scheme：A kind of constant temperature structure of belt transmission main shaft, including the first transmission main shaft, the second transmission main shaft, skin
Band, casing, the first belt pulley and the second belt pulley；First belt pulley is installed, described second passes on first transmission main shaft
The second belt pulley is installed on dynamic main shaft, connected between first belt pulley and the second belt pulley by belt transmission, it is described
First belt pulley, the second belt pulley and belt are respectively positioned in casing, during belt transmission by fan air inlet continue to
Injection air in casing, air is moved on the outside of exhaust outlet, air exhaust box with the express delivery of belt transmission direction and connects exhaust fan by casing
Interior air is extracted out, while the heat produced during taking away belt transmission.
Beneficial effect：The present invention increases by a casing to belt transmission part, air is injected into casing, and take out by air draft
Air is walked, so that the heat produced during taking away belt transmission, reduction temperature rise influences on main shaft, main shaft precision stability is improved
Energy.
Air is injected into casing by the way that fan air inlet is lasting during belt transmission, air is with belt transmission direction
Express delivery is moved to exhaust outlet, and air exhaust box outside connects exhaust fan and extracts air in casing out, while during taking away belt transmission
The heat of generation.
Temperature after this structure is used to be fluctuated only in 2 DEG C by actual measurement, while not to the part outside transmission case body
Radiations heat energy, effectively prevent the deformation that part is brought by heat influence, it is ensured that the stabilization of main shaft precision.
Brief description of the drawings
Fig. 1 is the existing structure schematic diagram in the present invention；
Fig. 2 is the structural representation in the present invention；
Air circulation schematic diagram in Fig. 3 present invention.
Embodiment
With reference to specific embodiment, the invention will be further described.
Embodiment
As shown in figure 1, existing main shaft of numerical control machine tool power transmission uses belt wheel belt transmission structure, this structure has peace
Dress is convenient, the features such as abnormal impact influence of transmission is small, but because the belt pulley 11 of belt 3 and first and the second belt pulley 21 rub and by
The heat that power deformation is produced can be such that the temperature of drive disk assembly quickly raises, because temperature rise brings the deformation of the drive disk assemblies such as main shaft, funeral
Mistake precision itself.
To ensure that machine tool accuracy is stable, the precision change that main shaft is brought by thermal deformation is reduced, the structure to running part is entered
Row modification, specifically as Figure 2-3, a kind of constant temperature structure of belt transmission main shaft, including the transmission of the first transmission main shaft 1, second
Main shaft 2, belt 3, casing 4, the first belt pulley 11 and the second belt pulley 21；First skin is installed on first transmission main shaft 1
Second belt pulley 21 is installed on belt wheel 11, second transmission main shaft 2, the belt pulley 21 of the first belt pulley 11 and second it
Between be connected by belt 3, first belt pulley 11, the second belt pulley 21 and belt 3 are respectively positioned in casing 4, in belt 3
Air is injected into casing 4 by the way that the air inlet 7 of blower fan 5 is lasting in transmission process, air is moved to the transmission direction express delivery of belt 3
Exhaust fan 6 is connect on the outside of exhaust outlet 8, air exhaust box to extract air in casing out, while the heat produced during taking away belt transmission
Amount.
One casing is increased to belt transmission part, the note into casing is continued by fan air inlet during belt transmission
Enter air, air is moved to exhaust outlet with the express delivery of belt transmission direction, and air exhaust box outside connects exhaust fan and takes out air in casing
Go out, while the heat produced during taking away belt transmission.
Temperature after this structure is used to be fluctuated only in 2 DEG C by actual measurement, while not to the part outside transmission case body
Radiations heat energy, effectively reduces the deformation that part is brought by heat influence, it is ensured that the stabilization of main shaft precision.
The present invention is not limited to above-mentioned preferred forms, and anyone can show that other are various under the enlightenment of the present invention
The product of form, however, make any change in its shape or structure, it is every that there is skill identical or similar to the present application
Art scheme, is within the scope of the present invention.
