Abstract
The utility model relates to a double-pipe upright worm and worm wheel lift for lifting a load, comprising a box body, an input flange, a worm wheel, a lifting screw rod and a double-lead worm, wherein the input flange is arranged on one side of the box body, the worm wheel and the double-lead worm are arranged in the box body, the worm is meshed with the double-lead worm, and the lifting screw rod is meshed with a middle through hole of the worm wheel; one end of the double-lead worm is arranged in the input flange through the box body, and the other end of the double-lead worm is connected with the inner wall of the box body through a first bearing; and two ends of the lifting screw rod extend out of the box body. The double-pipe upright worm and worm wheel lift disclosed by the utility model carries out transmission by utilizing the double-lead worm so as to effectively control the meshing interval between the worm and the worm wheel and enable a lift to stably run; when in use, if the transmission interval is increased due to abrasion, the worm and worm-wheel transmission pair can be recovered to be an initial lead and original precision as long as the axial position of the worm is regulated, so that the double-pipe upright worm and worm wheel lift is very economical and practical and reaches effects of low cost and long service life.
Description
Technical field
The utility model relates to the worm and wormwheel elevator structure, is specifically related to a kind of worm and wormwheel elevator of two-tube vertical type.
Background technology
The worm and wormwheel elevator of present two-tube vertical type is a kind of compact conformation that has, and transmitting ratio is big, and the gearing that has auto-lock function under certain condition, is one of the most frequently used reductor.But, be unfavorable for mechanical circular movement precision drive owing to after the worm and wheel wearing and tearing, can cause the increasing of worm and wheel back lash.
The utility model content
In order to overcome the deficiency of prior art, the purpose of the utility model has been to propose that a kind of cost is low, the worm and wormwheel elevator of the two-tube vertical type that is used for the lifting load of long service life.
In order to achieve the above object, the technical scheme that the utility model adopted is following:
A kind of worm and wormwheel elevator that is used for the two-tube vertical type of lifting load; It comprises casing, input flange, worm gear, elevating screw and two helical pitch worm screw; Input flange is installed in a side of casing; Worm gear, two helical pitch worm screw all are positioned at casing, worm gear and two helical pitch worm meshs, the middle through hole engagement of elevating screw and worm gear; The end of two helical pitch worm screws passes casing and is installed in the input flange, and the other end of two helical pitch worm screws is connected with the inwall of casing through clutch shaft bearing; Stretch out outside the casing at the two ends of elevating screw.
As preferred construction, the two ends of elevating screw are installed in respectively in casing and the following casing.
As preferred construction, clutch shaft bearing is a tapered roller bearing.
The utility model compared with prior art adopts two helical pitch worm drive, controls the back lash of worm and wheel effectively; Make elevator steady in the running, if cause drive gap to increase because wear and tear in the use, as long as at this moment adjust the axial location of worm screw; Can make the Worm and Worm Gear Driving pair return to initial helical pitch and revert to original precision; Do not need the worm screw, the worm gear that more renew, very economic, practical, cost is low, the effect of long service life thereby reach.
Description of drawings
Fig. 1 is the structural representation of the worm and wormwheel elevator of the two-tube vertical type that is used for the lifting load of the utility model preferred embodiment;
Fig. 2 is that the A-A of Fig. 1 is to scheme drawing.
Reference numeral: 1, worm gear; 2, two helical pitch worm screws; 3, elevating screw; 4, input flange; 5, clutch shaft bearing; 6, casing; 7, go up casing; 8, following casing.
The specific embodiment
Below, in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.
As depicted in figs. 1 and 2, a kind of worm and wormwheel elevator that is used for the two-tube vertical type of lifting load, it comprises casing 6, input flange 4, worm gear 1, elevating screw 3 and two helical pitch worm screw 2.
As preferred construction, the two ends of elevating screw 3 are installed in respectively in casing 7 and the following casing 8.
As preferred construction, clutch shaft bearing can be tapered roller bearing.
Present embodiment also has following characteristics:
1, casing adopts the HT250 material of band muscle, through the finite element analysis principle, makes product rigidity good, and intensity is high, compact mechanical structure, and the life-span is long;
2, install simple and easy, adopt hollow output shaft, make connect pattern flexibly, superior performance, be easy to Maintenance and Repair;
3, operate steadily, noise is little, durable in use;
4, worm gear adopts split type the connection with output shaft, and employing and iron core are integrated poured during cast copper, have reduced manufacturing cost widely;
Tolerance on fit adopted interference fit when 5, worm gear connected with working machine with hollow output shaft and hollow output shaft, and are steady in the time of can making the working machine running, avoid working machine when stopping and causing bench board " to rock ";
6, worm screw and one-level gear material all adopt 20CrMnTi, and heat treatment is whole carbonitriding, and gear and worm screw thread are after grinding, and precision can reach 6 grades; Worm gear adopts the stronger KK copper of resistance to abrasion simultaneously, and driving efficiency, service life and load-carrying capacity are improved greatly;
7, worm and gear adopts two helical pitch transmissions, can be through axially adjustment worm gear and worm mesh gap, and it is big to adjust the back lash of causing because of worm gear wearing and tearing when the work effectively, realization " Zero clearance engagement ";
8, when the design worm and gear, lead angle is little, can realize complete self-locking, avoids working machine in operation process, to have the phenomenon of counter-rotating to take place;
9, because the sideshake of worm and wheel can be controlled within the reasonable range effectively, remain correct meshing relation; And compact conformation, easy to adjust, thereby in the structure that requires continuously accurate calibration, extensively adopted, applicability is strong, and safe reliability is big.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
