Abstract
A double-journal flexible universal shaft includes a torque power device, an input shaft head, a front flexible shaft journal, a rigid shaft, a rear flexible shaft journal, an output shaft head and a screw rotor, wherein an output shaft of the power device is connected with the left end of the input shaft head; the right end of the input shaft head is connected with the left end of the front flexible shaft journal; the right end of the front flexible shaft journal is connected with the left end of the rigid shaft; the right end of the rigid shaft is connected with the left end of the rear flexible shaft journal; the right end of the rear flexible shaft is connected with the left end of the output shaft head; and the right end of the output shaft head is connected with the screw rotor. In the utility model, the two flexible shafts are separated by the rigid shaft, so as to meet requirements for torque and axial force transmission, and the flexibility of the entire device is excellent; as no force is remained between the input shaft and the output shaft, the equipment operates stably, consumes less energy, and has high efficiency, low noise, long service life, long production period and remarkable economic benefit.
Description
Technical field
The utility model is the member on the single-screw machine tool equipment, is a kind of pair of flexible cardan shaft of neck.
Background technique
In the existing single-screw machine tool, generally adopt joint cardan shaft alive between input shaft and the rotor or scratch a transmitting torque and axial force with the footpath.The shortcoming of joint cardan shaft of living is that the joint component wearing and tearing are big, and it is poor to bear axial force; The shortcoming of scratching axle with the footpath is but that the big words of the diameter of axle are born the strong flexible variation of axial force ability, and the words that the diameter of axle is little are flexible to improve but bear the axial force variation.The former is fragile, and the life-span is short, and is with short production cycle, and equipment needs frequent repair and replacement, and the equipment off-time is many, and management difficulty is big, and maintenance expenses is high, deficiency in economic performance.Latter's poor practicability.
Summary of the invention
The purpose of the utility model is a kind of pair of flexible cardan shaft of neck of design, overcomes the deficiency of existing technology, and it is operated steadily, and the life-span is long.
The purpose of the utility model is achieved in that and comprises torque power device, input spindle nose, preceding flexible axle journal, rigidity axle, the flexible axle journal in back, output shaft head, screw rotor; The output shaft of power plant is connected with input spindle nose left end; Input spindle nose right-hand member with before flexible axle journal left end be connected; Before flexible axle journal right-hand member be connected with rigidity axle left end; Rigidity axle right-hand member is connected with the flexible axle journal left end in back, and the flexible axle journal right-hand member in back is connected with the output shaft head left end, and the output shaft head right-hand member is connected with screw rotor.
The beneficial effect of the utility model is: two flexible axle journals are connected by the rigidity axle, can satisfy the requirement of transmitting torque and axial force, and single unit system are flexible good; The strength of not spraining during the screw rotor planetary motion, equipment operation is steady, less energy consumption; Efficient is high, noiseless, long service life; Manufacture cycle is long, has remarkable economic efficiency.
Description of drawings
Fig. 1 is the erection drawing of the utility model.
Embodiment
Below in conjunction with Fig. 1 the embodiment of the utility model is described.Can know that by figure the embodiment of the utility model comprises the flexible axle journal of torque power device 1, input spindle nose 2, preceding flexible axle journal 3, rigidity axle 4, back 5, output shaft head 6, screw rotor 7.The output shaft of power plant 1 is connected with input spindle nose 2 left ends; Input spindle nose 2 right-hand members with before flexible axle journal 3 left ends be connected; Before flexible axle journal 3 right-hand members be connected with rigidity axle 4 left ends; Rigidity axle 4 right-hand members are connected with flexible axle journal 5 left ends in back, and flexible axle journal 5 right-hand members in back are connected with output shaft head 6 left ends, and output shaft head 6 right-hand members are connected with screw rotor 7.
During work, screw rotor 7 is put into stator, power plant 1 outputting power; Drive 2 rotations of input spindle nose, thereby drive screw rotor 7 rotations, screw rotor 7 and stator auxiliary work; Realize the conveyance fluid medium, though screw rotor 7 is done planetary motion, equipment operation is steady.
If the utility model is used for down-hole oil production, will between torque power device 1, input spindle nose 2, connect drive link with the dark equal length of pump.
