Abstract
The utility model relates to a fan transmission device used on an air compressor, which comprises a fan assembly and is characterized in that the fan assembly is fixedly arranged on a fan blade connecting plate; the fan blade connecting plate is arranged on a fan blade supporting frame through a fastener; the fan blade supporting frame is arranged on a machine head spindle through a key; and the fan blade connecting plate is connected with the machine head spindle through an axial positioning bolt. Due to the adoption of the structure, a machine head can indirectly drive fan blades to rotate; for preventing a fan from axially moving, the fan assembly is positioned by the axial positioning bolt; and in the structure, no devices such as a bearing, a gland, a seal and the like are arranged. Therefore, the fan transmission device has a simple structure, high reliability, zero maintenance cost, permanent design of all the parts and no any maintenance cost in the later period. The energy-saving effect is obvious. The fan adopts the motorless design and is not provided with any heating parts. The design is reasonable. The cooling air quantity can be changed with variation of the capacity of the air compressor. The fan transmission device is more suitable for stable operation of the air compressor.
Description
Technical field
The utility model belongs to air compressor manufacturing technology field, particularly relates to a kind of fan drive that is used on the air compressor.
Background technique
Air compressor in use can produce a large amount of heat of compression, for the accumulation that prevents heat causes local thermal distortion excessive, air compressor has adopted the lubricant oil cooling, in order to guarantee the long-time normal operation of air compressor, requirement must be cooled off lubricant oil, to guarantee that air compressor has subzero oil supply endlessly, and air compressor belongs to the equipment of varying capacity, tolerance can be intelligent automatic regulated, and the big and little change of tolerance can cause the big and little variation of the heat dissipating capacity that needs.
Air compressor generally adopts fan that heat sink arrangement is forced the air draft cooling, usually adopt independently blower fan, drive the flabellum rotation by fan electromotor after connecting power supply, produce cooling air, the problem that this structure exists is: blower fan takes up room greatly, running gear is many, rate of fault is high, fan electromotor needs frequent maintenance or the like a series of problems.The most important thing is that fan electromotor can not change rotation speed of the fan according to the variation of compressor capacity, satisfy the cooling air quantity demand under the different heat dissipating capacities of air compressor, can only be in the air quantity design point operation of maximum, power consumption is big.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, running gear is few, stable, rotating speed adjustable be used for fan drive on the air compressor.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of fan drive that is used on the air compressor, comprise fan assembly, it is characterized in that: described fan assembly is packed on the flabellum connecting plate, described flabellum connecting plate is installed on the flabellum supporting frame by fastening piece, described flabellum supporting frame is installed on the head spindle by key, and the flabellum connecting plate is connected with head spindle by the axially locating bolt.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, be that fan assembly passes through the flabellum connecting plate and forces fixing, to improve the intensity of flabellum, be fixed on the flabellum supporting frame by the flabellum connecting plate again, and flabellum supporting frame design key cooperates installation with head, makes head can drive the flabellum rotation indirectly, moves axially in order to prevent fan, by the axially locating bolt fan assembly is located, in this structure, do not have devices such as bearing, gland, sealing.Therefore the utility model is simple in structure, reliability is high, zero dimension is protected expense, and all parts all are permanent designs, and the later stage does not have any maintenance cost; Remarkable energy-saving performance, this blower fan is no design of electrical motor, does not have any heating component; Reasonable in design: cooling air quantity can change according to the variation of air compressor capacity, is more suitable for the stable operation of air compressor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, fan assembly; 2, flabellum connecting plate; 3, fastening piece; 4, flabellum supporting frame; 5, head spindle; 6, axially locating bolt.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, a kind of fan drive that is used on the air compressor comprises fan assembly 1, and described fan assembly 1 is packed on the flabellum connecting plate 2, described flabellum connecting plate 2 is installed on the flabellum supporting frame 4 by fastening piece 3, and described flabellum supporting frame 4 is installed on the head spindle 5 by key.In order to prevent that fan from moving axially, flabellum connecting plate 2 is connected with head spindle 5 by axially locating bolt 6.
The said structure fan assembly is forced fixing by the flabellum connecting plate, to improve the intensity of flabellum, be fixed on the flabellum supporting frame by the flabellum connecting plate again, and flabellum supporting frame design key cooperates installation with head, make head can drive the flabellum rotation indirectly, in order to prevent that fan from moving axially, by the axially locating bolt fan assembly is located, in this structure, there are not devices such as bearing, gland, sealing.Therefore the utility model is simple in structure, reliability is high, zero dimension is protected expense, and all parts all are permanent designs, and the later stage does not have any maintenance cost; Remarkable energy-saving performance, this blower fan is no design of electrical motor, does not have any heating component; Reasonable in design: cooling air quantity can change according to the variation of air compressor capacity, is more suitable for the stable operation of air compressor.
