Abstract
The utility model discloses a novel worm and gear lifting device which is characterized by comprising a box body and a worm and gear mechanism fixedly arranged in the box body, wherein a worm shaft head extends out of the box body and is connected with external power; a lifting screw rod passes through and is arranged in the shaft center of a worm and is in threaded screw rod fit with the shaft center of the worm; the flange end of the lifting screw rod extends out of the box body; a guide sleeve is additionally arranged on the lifting screw rod; the bottom of the guide sleeve is fixed on the box body by a connecting piece; and a gap between the guide sleeve and the lifting screw rod can be adjusted by a locking disc spring and an adjusting bolt. The novel worm and gear lifting device has the advantages that the worm and the lifting screw rod are integrally connected with the box body; the lifting device has higher running reliability and can operate more stably; the lifting screw rod has better rigidity; and the motion precision of the lifting device is finished by the matched gap between the screw rod at the tail and the extended part of the box body and a locking device at the motion end. The lifting device can be used under various severe conditions of large vibration amplitude, poor environment condition, a certain upsetting moment and the like.
Description
Technical field
The utility model relates to a kind of new type worm wheel worm screw lowering or hoisting gear, is specially adapted to operating mode occasions such as high vibration, environment be abominable.
Background technique
Along with the development of industrial machinery, to as high vibration, the performance requirements such as lifting precision of the lift device under the situation such as environment is abominable are also more and more higher, require lift device to have higher running stability, better self-lock ability and better reliability.Traditional lift device is because its structure and annexation limit are poor to the adaptive capacity that turns round under this situation.
Summary of the invention
The purpose of this utility model is just at existing problem in the above-mentioned prior art and special development a kind of is suitable for the new type worm wheel worm screw lowering or hoisting gear that uses under situations such as vibration is strong, environment is abominable.
The purpose of this utility model is achieved through the following technical solutions: new type worm wheel worm screw lowering or hoisting gear of the present utility model, comprise casing and the worm-and-wheel gear that is packed in the casing, the worm screw spindle nose stretches out casing and is connected with outer power, the worm gear axle center is coated with elevating screw, cooperate for threaded screw rod between the two, the elevating screw flange end stretches out casing, on the elevating screw that is positioned at the casing outside, add guide sleeve, the guide sleeve bottom is fixed on the casing by link, gap between guide sleeve and the elevating screw is by locking dish spring and regulate the bolt adjusting, with the up rightness that guarantees that elevating screw moves up and down.
In the utility model, overall fixed links together between worm gear, elevating screw and the casing, to guarantee integral rigidity, precision and the running stability of lift device.The screw mandrel of elevating screw afterbody and casing extension are the accurate installation of Spielpassung; The tache motorice of elevating screw and guide sleeve are that adjustable clearance is installed.
The utility model is by with worm gear and elevating screw and rise integral installation between the device box.Both installations no longer rely on standard piece such as bearing, but directly make worm gear become as a whole with elevating screw with casing by cooperating to install with casing, thereby make the stressed distribution of lowering or hoisting gear more even, thereby increase the reliability that whole lowering or hoisting gear uses; In addition, locking dish spring is installed at elevating screw lifting position and is regulated bolt, regulate the installation of elevating screw, make the integral rigidity of elevating screw can access better assurance, simultaneously, locking nut can guarantee that also the auto-lock function of lift device under the high vibration environment can realize, thereby guarantees the reliability of lift device and institute's application apparatus.
Advantage of the present utility model is: worm gear and elevating screw and lowering or hoisting gear casing are integral installation, and the operating reliability of lowering or hoisting gear is higher, and it is more steady to turn round, and the rigidity of elevating screw is better; Gap adjustment between elevating screw and the guide sleeve can guarantee the up rightness that lifting bar moves up and down by regulating bolt and locking the dish spring and finish jointly.The locking of assurance lift device itself no longer only relies on the self-locking of worm and gear, makes the locking of lift device more reliable and stable.Such design can make the lift device can be big as Oscillation Amplitude, and environmental condition is poor, exists under the various abominable situation of certain tilting moment etc. to use.
Description of drawings
Fig. 1 is a structural front view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure: among the figure: 1. lock the dish spring, 2. regulate bolt, 3. guide sleeve, 4. elevating screw, 5. worm gear, 6. casing, 7. worm screw.
Embodiment
The utility model is described further below in conjunction with accompanying drawing:
As Fig. 1, shown in 2: new type worm wheel worm screw lowering or hoisting gear of the present utility model, comprise casing 6 and the worm-and-wheel gear that is packed in the casing, worm screw 7 spindle noses stretch out casing 6 and are connected with outer power, worm gear 5 axle center are coated with elevating screw 4, cooperate for threaded screw rod between the two, the elevating screw flange end stretches out casing 6, on the elevating screw 4 that is positioned at the casing outside, add guide sleeve 3, the guide sleeve bottom is fixed on the casing 6 by link (screw), gap between guide sleeve 3 and the elevating screw 4 is by locking dish spring 1 and regulate bolt 2 adjustings, with the up rightness that guarantees that elevating screw moves up and down.
In the utility model, overall fixed is connected between worm gear 5, elevating screw 4 and the casing 6, to guarantee the integral rigidity and the running stability of lowering or hoisting gear.
Working principle of the present utility model and process are as follows: worm gear is that gear pair is connected with worm screw, and the worm screw spindle nose stretches out the lift device casing, accepts external drive, outside rotation motion is transmitted be the rotation motion of worm gear; Worm gear is connected to screw mandrel with lifting bar and is connected, and the rotation motion of worm gear is converted to moving up and down of elevating screw.Promptly when the worm screw forward rotation, elevating screw is a propradation, and the backward rotation elevating screw is the decline state.The elevating screw guide sleeve is installed on casing, regulates bolt and locking dish spring,, guarantee vertical motion when elevating screw is moved up and down by regulating the suitable elevating screw of bolt and the adjustable integration of locking dish spring and the gap of guide sleeve.
Claims (2)
1. new type worm wheel worm screw lowering or hoisting gear, it is characterized in that, comprise casing and the worm-and-wheel gear that is packed in the casing, the worm screw spindle nose stretches out casing and is connected with outer power, the worm gear axle center is coated with elevating screw, cooperate for threaded screw rod between the two, the elevating screw flange end stretches out casing, on the elevating screw that is positioned at the casing outside, add guide sleeve, the guide sleeve bottom is fixed on the casing by link, and the gap between guide sleeve and the elevating screw is regulated by locking dish spring and adjusting bolt.
