Abstract

Disclosed is a double-rotor centrifugal fanner, both ends of whose principal shaft are provided with rotors. The utility model is characterized in that the principal shaft of the fanner is supported by two sets of shaft block assemblies with oil tanks; a triangular belt pulley gear is arranged at the middle to drive; triangular belt storage tanks are arranged at the two sides of the triangular belt pulley to store spare triangular belts; the whole body of the fanner is supported by a steel bracket with a vibration decreasing leather cup; two ends of the principal shaft of the fanner are provided with matching shells and rotors with the same specification, the same diameter and opposite rotation directions. The utility model solves the problem that axially parallel air draft needs two current centrifugal fanners and the size is too big, thus the utility model is particularly suitable to be matched with a fanner in occasions that axially parallel air draft or small-sized and light fanner is needed.

Description

The double rotor centrifugal fan
Affiliated technical field
The utility model relates to a kind of ventilating machinary device that makes gas produce flow and pressure, double rotor centrifugal fan that especially can axial air draught in parallel.
Background technique
At present, the air draught mode of known centrifugal fan has one-sided air draught 1, and 2 three kinds of bilateral air draught 0 and two-stage tandems do not have air draught mode in parallel; The supporting kind of drive has the direct drive A formula of motor, and the cantilever support belt pulley is located at the B formula of transmission in the middle of two bearing supports, and the cantilever support belt pulley is located at the C formula of bearing support outside transmission and suspended wall supporting with totally four kinds of the D formulas of coupling transmission; No matter which kind of the air draught mode and the supporting kind of drive all are that fan rotor is located at a side, opposite side is established the supporting transmission device.For example one-sided air draught, the centrifugal fan of the C formula supporting kind of drive is an end that fan rotor is contained in main shaft, is furnished with corresponding casing, with conjuncted bearing support assembly supporting, establish the transmission of vee-pulley transmission device at the other end of main shaft, the integral body of blower fan is by the supporting of band vibration damping leather cup steelframe.It is strong that this ventilator has integrity, vibrates little and the advantage such as steady that turns round, and the environment that is used for single air intake pipe is more satisfactory.But volume is bigger than normal, and particularly if this ventilator is used for two environment axially in parallel of needs, axial dimension is just bigger, in some particular environment, can't arrange at all.
Summary of the invention
Bigger than normal in order to overcome existing centrifugal fan volume, particularly need two excessive problems of axial axial dimension in parallel, the utility model provides a kind of double rotor centrifugal fan, this double rotor centrifugal fan has not only solved existing centrifugal fan volume problem bigger than normal, and makes things convenient for the specific environment layout that needs axial air draught in parallel at some especially.
The technological scheme that its technical problem that solves the utility model adopts is: blower fan main shaft is by two cover band fuel tank bearing support assembly supportings, the transmission of vee-pulley transmission device is established in the centre, the vee-pulley both sides of vee-pulley transmission device are provided with the vee belt container, the integral body of blower fan is by the supporting of band vibration damping leather cup steelframe, it is identical that model is equipped with at the two ends of blower fan main shaft respectively, equal diameters, fan rotor that rotation direction is opposite and supporting casing, drag the fan rotor rotation by transmission device during work, the constraint of casing, the pressure that gas is produced equals the pressure of former type, and the flow summation of generation equals the twice of former type.The vee belt container is a ring groove shape opening casing, is fixed on band vibration damping leather cup steelframe supporting strap fuel tank bearing support assembly place, is used to store standby vee belt.
The beneficial effects of the utility model are, conveniently need the specific environment of axial air draught in parallel to arrange at some, or are matched in other multitube multicell device systems, make airduct arrange become succinct and miniaturization, and the flow of gas and pressure are evenly distributed; Existing relatively centrifugal fan, an only many cover fan rotor and casings, simple in structure, and the gas flow summation that produces is exactly the twice of former type, therefore, produce the identical existing centrifugal fan of same gas flow fan rotor model relatively, volume is little in light weight.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model double rotor centrifugal fan structural representation
Fig. 2 is the centrifugal fan structural representation of the existing C formula supporting kind of drive, is a kind of supplemental instruction to background technique
Among the figure 1, casing, 2, fan rotor, 3, blower fan main shaft, 4, band fuel tank bearing support assembly, 5, the vee-pulley transmission device, 6, the vee belt container, 7, fan rotor, 8, casing, 9, band vibration damping leather cup steelframe.
Specific embodiments:
In Fig. 1, blower fan main shaft (3) is by two cover band fuel tank bearing support assembly (4) supportings, vee-pulley transmission device (5) transmission is established in the centre, the vee-pulley both sides of vee-pulley transmission device (5) are provided with vee belt container (6), the integral body of blower fan is by band vibration damping leather cup steelframe (9) supporting, it is identical that model is equipped with at the two ends of blower fan main shaft (3) respectively, equal diameters, fan rotor that rotation direction is opposite (2) and fan rotor (7), and be furnished with supporting casing (1) and casing (8) respectively, drag fan rotor rotation, the constraint of casing by transmission device during work, the pressure that gas is produced equals the pressure of former type, and the flow summation of generation equals the twice of former type.Vee belt container (6) is a ring groove shape opening casing, is fixed in band vibration damping leather cup steelframe (9) supporting strap fuel tank bearing support assembly (4) and locates, and is used to store standby vee belt, and its storage capacity equals component repairing or replacement cycle institute's requirement amount on the axle.

Claims (2)

1, a kind of double rotor centrifugal fan, it is that blower fan main shaft is by two cover band fuel tank bearing assembly supportings, vee-pulley transmission device and two vee belt containers are established in the centre, the integral body of blower fan is by the supporting of band vibration damping leather cup steelframe, it is characterized in that: it is identical that model is equipped with at the two ends of blower fan main shaft respectively, equal diameters, the fan rotor that rotation direction is opposite and supporting casing.
2, double rotor centrifugal fan according to claim 1 is characterized in that: the vee belt container is a ring groove shape opening casing, is arranged on the vee-pulley both sides of vee-pulley transmission device, is fixed on the band vibration damping leather cup steelframe.
