Abstract
The utility model discloses a simple single screw compressor which comprises a shell used for containing a screw rotor and a motor used for driving the screw rotor to rotate, wherein the shell is internally provided with a star wheel meshing with the screw rotor by a driving way, the screw rotor is arranged on a motor shaft at the output end of the motor, and the shell is connected to an end housing flange of the motor through a contact flange. The utility model directly fixes and arranges the screw rotor on the motor shaft, overcomes the additional radial force action brought by the belt driving and the installation disalignment of a coupler, improves the service life of the compressor, and reduces the energy consumption of the compressor. Meanwhile, because the motor shaft is changed, the utility model reduces raw materials, lightens the weight, reduces the processing of parts, has simple structure, improves the installation efficiency, and greatly lowers the manufacture cost of the single screw compressor.
Description
Technical field
The utility model relates to a kind of air compressor, is a kind of easy single screw compressor specifically.
Background technique
Single screw compressor on the prior art, head are independently parts, connect with motor by direct connection or belt transmission.When being direct connection, need a cover coupling, main frame is connected with head by coupling; When being belt transmission, need a cover drive pulley and a belt.No matter be that direct connection or belt connect, the screw rotor of its compressor has independently main shaft, bearing and bearing block bearing, and screw rotor is fixed on the casing.Like this, be connected with coupling or belt pulley and belt thereof, main frame has main shaft, axle, bearing support, and part is many, and processing cost is also high naturally, and assembling difficulty is big, and its man-hour is also many, and cost is also high naturally.When coupling is installed decentraction, bring extra radial force effect can for the main shaft of main frame and motor, also to the load of the bearing on the main shaft of motor and main frame, bearing life is shortened.When being belt transmission, because belt transmission has very big radial force effect, the load extra to bringing of the bearing on the main shaft of motor and main frame shortens life-span of bearing greatly, promptly shortens the life-span of motor and main frame.And coupling and belt pulley transmission have the transfer efficiency waste, increases the energy consumption of compressor.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, use and to receive a mandate long and effectively reduce the easy single screw compressor that cost drops into.
Goal of the invention of the present utility model is achieved in that a kind of easy single screw compressor, comprise the housing that is used for ccontaining screw rotor and be used for the motor of drive screw rotor rotation, be provided with the star-wheel that rotates with the screw rotor engagement in the housing, it is characterized in that: described screw rotor is installed on the motor shaft of motor output end.
Described housing is connected on the end housing flange of motor by adpting flange.
Described adpting flange independently is installed on the housing or with housing and is integrated.
Described adpting flange is provided with the recessed edge of seam, and the end housing flange of motor is provided with the seam convex edge of mating mutually with the recessed edge of seam, and is concentric with the screw of housing to guarantee motor shaft.
Described motor shaft is a multidiameter shaft, and its outermost axle head runs through the screw rotor center hole and extends the end of screw rotor, and the tail end that motor shaft stretches out screw rotor is provided with locking element, on the outermost axle head that screw rotor is fixed on motor shaft.
Be provided with the sleeve that is loaded on the motor shaft between the flange of described screw rotor and motor.
The utility model improves the easy single screw compressor of prior art, and motor shaft is prolonged, and screw rotor directly is fixed on the axle of motor motor and the running of screw host common motor axle.Because it is stress balance that single screw compressor has the advantage of self, so screw rotor is not subjected to the external force effect when work, promptly its motor shaft there is not the additional force effect, motor shaft only needs the driving torque effect, overcome because coupling is installed the additional radial power effect that decentraction and belt transmission are brought, the working life of having improved compressor.Because of motor shaft runs through the screw rod center hole, and have locking element that motor shaft and screw rod are carried out fixed-site at the screw rod end, transmission efficiency height like this reduces the energy consumption of compressor.While is because of the change of motor shaft, original coupling or belt drive system have been save, the bearing at screw rotor main shaft and two ends thereof, therefore bearing support reduces raw material, has alleviated weight, reduce the processing of part, simple in structure, improved the installation efficiency height, greatly reduce the manufacture cost of single screw compressor.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Accompanying drawing 2 is another embodiment's of the utility model a structural representation.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
With reference to the accompanying drawings 1 and shown in Figure 2, easy single screw compressor described in the utility model, comprise the housing 2 that is used for ccontaining screw rotor 1 and be used for the motor 3 that drive screw rotor 1 rotates, be provided with the star-wheel 4 that rotates with screw rotor 1 engagement in the housing 2, screw rotor 1 cooperates two star-wheel 4 meshing runnings usually, two star-wheels 4 are as the criterion with the axis of screw rotor 1 and are symmetrical distribution, constitute screw rod star-wheel 4 pairs.Screw rotor 1 described in the utility model is installed on the motor shaft 31 of motor 3 output terminals.Be that motor shaft 31 stretches out, screw rotor 1 can be flush-mounted on the motor shaft 31 fully, the main shaft that motor shaft 31 becomes screw rotor 1 simultaneously drives screw rod run-in synchronism.Simultaneously, housing 2 is connected in by adpting flange 21 on the end housing flange 32 of motor 3, and this adpting flange 21 independently is installed on the housing 2, as shown in Figure 2, perhaps adpting flange 21 is integrated with housing 2, and as shown in Figure 1, adpting flange 21 is together cast with housing 2 and formed.Motor shaft 31 is a multidiameter shaft, its outermost axle head runs through screw rotor 1 center hole and extends the end of screw rotor 1, the tail end that motor shaft 31 stretches out screw rotor 1 is provided with locking element 5, screw rotor 1 is fixed on the outermost axle head of motor shaft 31, this locking element 5 can be the bearing pin that inserts motor shaft 31, perhaps is used with shaft end ring and bolt.During this time, be provided with the sleeve 6 that is loaded on the motor shaft 31 between the flange 32 of screw rotor 1 and motor 3, can utilize sleeve 6 and locking element 5 screw rotor 1 to be positioned at the stepped end of motor shaft 31 ends on the one hand, on the other hand also can be by abrasive sleeve 6 adjusting the axial position of screw rotor 1, in ideal range, overlap with center between the star-wheel 4 to guarantee screw slot.Simultaneously, it is recessed along 7 that adpting flange 21 is provided with seam, and the end housing flange 32 of motor 3 is provided with seam recessed along the 7 seam convex edges 33 of mating mutually, and is concentric with the screw of housing 2 to guarantee motor shaft 31.
