Abstract
The utility model discloses a motive device for a long screw drill which is composed of a steel support frame, a reduction case connected with the steel support frame, two motors arranged on the case, and a speed reducing mechanism in the case. The two motors are arranged side by side, and the dynamic force is transmitted to two input wobble shafts of the speed reducing mechanism in the reduction case through a shaft connector. The two wobble shafts are arranged in parallel, and are connected as a whole by a gear toothed plate whose toothed ring is meshed with a hollow main shaft. The upper part and lower part of the hollow main shaft are connected with the case by a bearing support member. The utility model has simple structure, small size, and high impact resistance performance. The first level gear can satisfy speed ratio requirement of the drill, and the utility model is reliable and durable.
Description
The utility model belongs to the power set that use on the building machinery field, particularly auger machine.
Its power set of existing full screw earth auger adopt all the time traditional multistage kind of drive as: V-Belt Drive to bevel gear transmission, two-stage planet drives to column gear transmission, two grades of roller gear gear to column gear transmission or pinwheel cycloid drive to column gear transmission etc.Owing to be multistage transmission, the structure of power set certainly will be complicated, and the volume and weight of device must increase.In addition, its axial force of the main shaft of power set generally all is to pass to casing and case lid respectively by bearing, and case lid is relatively weaker, so stress is not good.In use not only vibration is big for this class device, noise is high, and maintenance and maintenance are also inconvenient.The utility model purpose is to propose the novel power device that full screw earth auger was improved and be exclusively used in to a kind of process at the problems referred to above.This apparatus structure is simple, transmission progression is few, hollow main shaft supporting force-bearing situation is good, noise is low, vibration is little, simple to operate, running steadily, maintenance conveniently.
The utility model is realized by following scheme.Use for reference China's No. 85106692.5 patents described " three-ring speed reducer ", the structural form of lacking the transmission of tooth difference tooth plate is organically combined with auger machine, make it to be fit to the specification requirement of bore operation.When these power set of design and manufacture, by measures such as entire arrangement and inside and outside connections necessary support component is set, to overcome drilling machine suffered load when the operation.The mud jacking again because full screw earth auger should be holed in operation is so the main shaft of rig also will connect center mud jacking swivel coupling except that possessing the hollow structure.In addition, the advancing brill power, pull out brill power and moment of torsion all passes through drilling rod reaction what main shaft of rig, so the structure setting of main shaft support then is a very important problem.In order to resolve the support problem, will few tooth difference tooth plate transmission mechanism be set on the reduction case that motor is fixed on steel frame connects and in casing, make transmission mechanism and casing and steel frame form an integral body.Its upper-lower position of the central principal axis of transmission mechanism is connected in the top and the bottom of casing respectively by bearing supports, main force part is placed on bottom half, improve the support structure form of device on the whole, make rig reach strong, the reliable and stable instructions for use of load-bearing capacity.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.Fig. 1 is a full screw earth auger novel power device organigram.Fig. 2 is the hollow main shaft support organigram of power set reducing gear.Fig. 3 is that hollow main shaft upper end is connected organigram with the mud jacking swivel coupling.Fig. 4, Fig. 5 are the shaft joint organigram.
With reference to accompanying drawing, the utility model mainly by steel bracing frame (1), the reduction case (5) that is connected with bracing frame (1) and be arranged on bi-motor (2) on the casing (5) and casing (5) in reducing gear etc. form.Bi-motor is set up side by side, two input eccentric shafts (8) in shaft joint (4) is passed to power reduction case (5).Two input eccentric shafts (8) be arranged in parallel, it are connected as a single entity in the mode that is connected by three tooth plates (9).Driving toothed plate (9) meshes with the gear (10) of hollow main shaft (7).Below the gear (10) of hollow main shaft (7) a pair of self-aligning thrust roller bearing of laying with back-to-back form (15) (17) is set, bearing also can be up big and down small tapered roller bearing.The outer ring of bearing (15) (17) cooperates installation with the endoporus of casing (5) bottom bearing cover for seat (16).Bearing sleeve (16) endoporus has the annular lip structure, is used to retrain the axial displacement of bearing (15) (17).Be to connect dish (6) below the bearing (15) (17).Connect and a big round nut (18) is set below the dish (6), the shaft shoulder of hollow main shaft is adjusted the end play of bearing (15) (17) below big round nut (18) and gear (10).Bearing (17) bears into brill power, and bearing (15) bears the brill power of pulling out.
On the gear (10) of hollow main shaft (7) self-aligning roller bearing (11) is set, its outer ring cooperates installation with bearing sleeve (14) endoporus of casing (5) loam cake.Between self-aligning roller bearing (11) and the upper ball cover space is arranged, can get rid of the axial constraint of bearing (11) with respect to casing (5) like this, make case lid not be subjected to the influence of axial force, structure can alleviate, attenuate.The installation position of self-aligning roller bearing (11) is lower than the upper box lid of casing (5), so that take flooding system lubrication, pasta top is still had living space, and the unlikely oil that causes is warm higher.The upper end of hollow main shaft (7) is connected with center (19) bolt of mud jacking swivel coupling (3).Be provided with O RunddichtringO (20) between the umbrella hood of center (19) and the oil seal cover (12), in case mud enters casing.Center (19) by sleeve (13) with self-aligning roller bearing (11) axial constraint on hollow main shaft (7).The bearing sleeve of box cover (14) is fastenedly connected with the overcoat (21) of swivel coupling (3).Overcoat (21) is connected with sealing shroud (22) again.In order to remedy the alignment error between motor and the power shaft, what the shaft joint in the transmission mechanism (4) adopted is single nylon pin shaft joint.It is made up of top shaft coupling (23) and bottom shaft coupling (24).Process some column pin holes at shaft coupling circumference faying face position up and down.In the hole, place nylon pin (25).The shaft joint of this structure is shorter than the double nylon pin shaft joint axial dimension of standard, can satisfy instructions for use.
The utility model is owing to adopted structural form and the necessary integrated support structure of the transmission of few teeth difference tooth plate, thereby make power set in use produce new effect as: 1. the one-level transmission just can be satisfied the speed ratio requirement of drilling machine, 2. the locus is left in hollow main shaft upper end, be fit to install the mud jacking swivel coupling of different instructions for uses, 3. hollow main shaft and casing are stressed simple, have improved the stress of case lid; 4. overload property, resistance to shock loads performance are good, reliability and durability, 5. simple structure, volume is little, one-time investment is low.
