Abstract

The utility model relates to an electric screw rod vertical jack, which has the technical scheme that one side of an original screw rod vertical jack is provided with a DC motor and a planetary speed reducer which are connected by screws; a central gear is connected with a speed reduction disk with the central gear through a planetary gear, the speed reduction disk with the central gear is connected with a speed reduction disk with an output shaft through the planetary gear and the speed reduction disk with the output shaft is connected with a shaft connector and a small bevel gear through a bearing. Because the electric screw rod vertical jack changes the original hand operation into the motor which drives the planetary speed reducer and the screw rod to rotate to realize the jacking or dropping of the jack, the utility model overcomes the defects of labor consumption and time consumption when a tyre is changed by a driver.

Description

The vertical jack of electric screw
One, technical field
The utility model relates to the jack that various miniature cars use, and the vertical jack of specifically a kind of electric screw is a necessary tool on the miniature car.
Two, background technology
The jack of being joined on the present known automobile has screw rod horizontal type jack, the vertical jack of screw rod, hydraulic jack etc.These jacks are generally by base, support, mesh elevating screw with support by nut, the platform that contacts with supported material and constitute with the joining operating handle of elevating screw, but these jacks they when Vehicle tyre mounting or dismounting keeps in repair, its liter or fall and all adopt hand (or hand) to finish, so it is time-consuming to change tire and maintenance process and effort thereof at automobile, particularly popularize Tourism development along with family car.Under the situation of field and bad weather, carry out Vehicle tyre mounting or dismounting and maintenance trouble especially.
Three, summary of the invention
At the shortcoming that above-mentioned original jack exists, the technical scheme of the utility model technical issues that need to address and proposition is to overcome the defective that prior art exists, and provides more convenient, the more time saving and energy saving electric screw of a kind of lifting vertical jack.
The technical scheme of the utility model electric vertical jack is: it comprises: DC machine, screw, planetary reduction gear, the vertical jack of former screw rod mechanism, sun gear, the outer ring inner gear, planetary wheel, band sun gear deceleration dish, band output shaft deceleration dish, bearing and drive coupling etc., its structure is provided with a DC machine (1) and secondary or multistage planet retarder (3) at the side of former vertical jack, DC machine (1) and planetary reduction gear (3) arranged coaxial, connect by screw (2), planetary reduction gear (3) is connected by screw (11) with former vertical jack housing (14).Planetary reduction gear (3) is by sun gear (5), outer ring inner gear (6) and planetary wheel (4) are formed, sun gear (5) is installed in the middle of 3 planetary wheels, sun gear (5) is connected to first speed reduction gearing by planetary wheel (4) and band sun gear deceleration dish (7), and outer ring inner gear (6) is the transmission gear of planetary wheel (4).Band sun gear deceleration dish (7) is connected to second speed reduction gearing by planetary wheel (4) and band output shaft deceleration dish (8), and same outer ring inner gear (6) is the transmission gear of planetary wheel (4).Band output shaft deceleration dish (8) is connected with drive coupling (10) and bevel pinion (12) by bearing (9).
Enforcement advantage of the present utility model: the sun gear (5) that drives planetary reduction gear (3) during DC machine (1) energising rotation, because outer ring inner gear (6) is fixed, force planetary wheel (4) to do circular motion at a slow speed, reach one-level deceleration effect around sun gear (11); Band sun gear deceleration dish (7) rotation drives planetary wheel (4) makes output shaft deceleration dish (8) rotation reach the double reduction effect.Output shaft deceleration dish (8) is connected with bevel pinion (12) by bearing (9), coupler (10), drives bevel pinion (12) rotation.Because large bevel gear (13) links together with screw rod (18), so bevel pinion (12) drives screw rod (18) rotation by large bevel gear (13), the lower end of screw rod (17) is connected by thrust baring (15), when screw rod (18) rotates, according to the hand of rotation difference, jacking sleeve (17) is moved up or down, can realize that jack jacking block (19) rises or decline, laborsaving saving time during operation, convenient especially when needing changing of tire.
Four, description of drawings
Fig. 1 is the vertical jack master of a utility model electric screw cutaway view.
Fig. 2 is the structure cutaway view of planetary reduction gear.
Fig. 3 is the structure transverse sectional view of planetary reduction gear.
Among the figure 1, DC machine; 2, screw; 3, planetary reduction gear; 4, planetary wheel; 5, sun gear; 6, outer ring inner gear; 7, band sun gear deceleration dish; 8, band output shaft deceleration dish; 9, bearing; 10, coupler; 11, screw; 12, bevel pinion; 13, large bevel gear; 14, former vertical jack housing; 15, bearing; 16, base; 17, jacking sleeve; 18, screw rod; 19, jacking block.
Fig. 1 illustrates: direct current generator (1) connects by screw (2) and planetary reduction gear (3) Connect, planetary reduction gear (3) is connected with former upright jack housing (14) by screw (11).
Fig. 2 illustrates: screw (2) is connected with motor (1), and planetary gear (4) together Central gear (5) is first reducing gear, and outer ring internal gear (6) is the biography of planetary gear (4) Moving gear, band central gear deceleration dish (7) is first reducing gear with planetary gear (4), and is same Outer ring internal gear (6) is the travelling gear of planetary gear (4), planetary gear (4) and band output Axle deceleration dish (8) connects. Band output shaft deceleration dish (8) is by bearing (9) and shaft coupling (10) Connect.
Fig. 3 illustrates: the structure of planetary reduction gear (3) is by three planetary gears, outer ring internal tooth Wheel, central gear form, and central pinion is installed in the middle of three planetary gears.
Five, specific embodiments
Below in conjunction with accompanying drawing the utility model implementation process is described further: the power supply of DC machine (1) to DC machine (1), is realized electric vertical jack lifting work by special-purpose direction switch from the jack of automobile cigarette lighter.When automobile need be used the electric vertical jack, by special-purpose direction switch, the electric motor starting rotation, drive the sun gear (5) of planetary reduction gear (3), because outer ring inner gear (6) is fixed, and forces planetary wheel (5) to do circular motion at a slow speed around sun gear (4), band sun gear deceleration dish (7) links together with three planetary wheels, so band sun gear deceleration dish (7) reaches the effect that one-level is slowed down with three planetary wheels (5) rotation.Band sun gear deceleration dish (7) drives planetary wheel (5) makes output shaft deceleration dish (8) rotation reach the effect of double reduction.Output shaft deceleration dish (8) is connected with bevel pinion (12) by coupler (11), bevel pinion (12) drives screw rod (18) by large bevel gear (13) and is just doing or contrarotation, according to screw rod hand of rotation difference, jack jacking block (19) is risen or descend, reach the very heavy not only laborsaving but also time-saving purpose of tire of taking one's place.
