Abstract
The utility model relates to a worm wheel lead screw lift that lead screw does not rotate, including box, worm wheel, worm, lead screw, workstation, left end lid, right-hand member lid, top cap, the workstation is connected with the lead screw upper end, the lead screw passes the top cap and constitutes screw drive with the worm wheel, and the top cap is installed at the box upside, and the worm wheel teeth of a cogwheel contact with the worm screw and constitute worm gear, and the left end lid is passed on the worm left side, and the right-hand member lid is passed on the worm right side, and the left end lid is installed in the box left side. In the lifting process of the existing worm lifter, the screw rod can generate rotary motion to damage production. The invention has the advantages that: the outer surface of the screw rod and the inner surface of the middle hole of the top cover are changed into incomplete cylindrical surfaces, so that the screw rod and the top cover can only move relatively and can not rotate relatively in the matching process, and the screw rod can not generate rotary motion in the lifting process. The utility model discloses simple structure, the function is reliable and stable, convenient operation.
Description
Technical Field
The utility model relates to a jacking equipment, especially a worm wheel lead screw lift that lead screw is irrotational.
Background
In the existing worm wheel screw rod lifter, a worm rotates to drive a worm wheel to rotate, and then the worm wheel rotates to drive a screw rod to move up and down. Such elevators have been mass produced on the market. However, the elevator has the defect that when the worm wheel drives the screw rod to move up and down, the screw rod generates the torque which is the same as the rotation torque of the worm wheel, so that the screw rod has a tendency of rotation, the tendency is useless in the lifting process, and even the lifted object generates rotation movement, so that the safety production is adversely affected.
Disclosure of Invention
In order to overcome prior art, the defect that worm lift produced rotary motion at the in-process lead screw that lifts, the utility model provides a change the lift of lead screw and top cap appearance to the restriction is lifting the rotation of in-process lead screw.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a worm wheel lead screw lift that lead screw is irrotational, includes box, worm wheel, worm, lead screw, workstation, left end lid, right-hand member lid, top cap, upside thrust ball bearing, downside thrust ball bearing, left side deep groove ball bearing, right side deep groove ball bearing, its characterized in that: the workbench is connected with the upper end of a screw rod, the screw rod passes through a top cover to be in threaded connection with a worm wheel, the top cover is arranged on the upper side of a box body, the worm wheel, an upper thrust ball bearing, a lower thrust ball bearing, a left deep groove ball bearing and a right deep groove ball bearing are arranged in the box body, the lower thrust ball bearing is arranged below the worm wheel, the lower thrust ball bearing is simultaneously arranged at the bottom in the box body, the upper thrust ball bearing is arranged above the worm wheel, the upper thrust ball bearing is simultaneously arranged at the top in the box body, the teeth of the worm wheel are in contact with the threads of the worm to form worm wheel transmission, the left deep groove ball bearing is arranged on the left side of the worm, the left deep groove ball bearing is simultaneously arranged in a left bearing hole of the box body, the right deep, the right end cover is arranged on the right side of the box body.
The worm lifting device with the irrotational screw rod is characterized in that a through hole is formed in the center of the worm wheel, trapezoidal threads are arranged on the inner side of the through hole, a thrust bearing is arranged on the upper side of the worm wheel, a top cover is arranged on the upper side of the thrust bearing, and the thrust bearing is arranged on the lower side of the worm wheel and fixed on the box body.
According to the worm wheel screw rod lifter with the non-rotating screw rod, the circumference of the screw rod is provided with trapezoidal threads, the screw rod is matched with a threaded hole in the center of the worm to form thread transmission, and the appearance of the screw rod is an incomplete cylinder as shown in figure 2.
According to the worm wheel screw rod lifter with the irrotational screw rod, the through hole is formed in the center of the top cover, the appearance of the through hole is an incomplete cylindrical surface, and the screw rod penetrates through the top cover to be matched with the through hole of the top cover.
According to the worm wheel screw rod lifter with the irrotational screw rod, the deep groove ball bearings are mounted in the box body to support the worm, and the left end cover and the right end cover are respectively fixed with the deep groove ball bearings on two sides.
According to the worm wheel and screw rod lifter with the non-rotating screw rod, the worm is mounted on the deep groove ball bearing and meshed with the worm wheel, the worm transmits the rotary motion to the worm wheel, the worm wheel transmits the rotary motion to the screw rod, and the screw rod moves up and down.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic view of the present invention;
in the figure, the device comprises a left end cover 1, a left deep groove ball bearing 2, a left deep groove ball bearing 3, a worm, 4, a box body 5, an upper thrust ball bearing 6, a top cover 7, a screw rod 8, a workbench 9, a worm wheel 10, a right end cover 11, a right deep groove ball bearing 12 and a lower thrust ball bearing.
Fig. 2 is an outline view of the present invention.
FIG. 3 is a transmission schematic diagram of the present invention;
in the drawing, a worm is a driving part and drives a worm wheel to rotate, the worm wheel and a screw rod form a spiral transmission mechanism, and the worm wheel rotates to drive the screw rod to move up and down, so that the workbench is driven to move up and down.
FIG. 4 is an exploded view of the present invention;
in the figure, the assembly relation of each part is clear.
FIG. 5 is a view of the screw rod of the present invention; fig. 6 is an outline view of the top cover of the present invention.
Fig. 7 is an assembly view of the screw rod and the top cover of the present invention.
Detailed Description
The worm is a driving part, when the worm is rotated, the worm drives the worm wheel to rotate, the worm wheel and the screw rod form a spiral transmission mechanism, and the worm wheel rotates to drive the screw rod to move up and down, so that the workbench is driven to move up and down. The turbine rotates and also can produce the torque and lead to the lead screw to rotate when driving the lead screw and reciprocate, but the rotation of lead screw is harmful in the use, thereby the utility model discloses a thereby change the appearance restriction lead screw of lead screw and top cap and rotate, like figure 5, figure 6, the assembly relation of lead screw and top cap is like figure 7.
