Description

A kind of greenhouse curtain-rolling machine fewer differential teeth planetary decelerator structure

Technical field

The utility model relates to a kind of greenhouse curtain-rolling machine fewer differential teeth planetary decelerator structure, belongs to mechanical field.

Background technology

At present, greenhouse curtain-rolling machine curtain machine reducing gear is mainly by motor pulley, the gearbox driven pulley, power input shaft, II level variable-speed shaft, power take-off and input shaft gear, II level variable-speed shaft gear, output shaft gear, parts such as gearbox body are formed, by belt pulley and two bead apexes with the transmission of power of electromotor to the gearbox power input shaft, then by three grades of straight spur gears in the gearbox with transmission of power to output shaft, to obtain the required power of scrolling straw screen or mat, after roller shutter is finished, for preventing the straw screen or mat revolution, its braking mainly is to pass through brake disc, brake(-holder) block, ratchet, ratchet, parts such as torsion spring guarantee.Because this kind greenhouse curtain-rolling machine reducing gear complex structure, volume, weight are big, part is various, and the braking ability instability, former greenhouse curtain-rolling machine slowing-down structure has part processing, assembly process process is poor, maintenance difficult thereby make, dependability is poor, shortcomings such as manufacturing cost and selling price height are unfavorable for alleviating user's financial burden, have also brought certain difficulty to production marketing.

Summary of the invention

The purpose of this utility model provides a kind of novel greenhouse curtain-rolling machine fewer differential teeth planetary decelerator structure, and it is made up of motor gear, driving gear, driving shaft, gear chamber cover, gear chamber, casing, balance weight, eccentric bushing, planetary gear, ring gear, driven internal gear, output shaft, 5 kinds of bearings.Its operation principle is: when motor reel turns clockwise, the drive motor gear is done and is turned clockwise, the driving gear that is engaged with is then done and is rotated counterclockwise, driving gear drive driving shaft and eccentric bushing are done and are rotated counterclockwise, driving driven internal gear by planetary gear does and is rotated counterclockwise, planetary gear drive output shaft is done and is rotated counterclockwise, fixing ring gear makes the planetary gear that is contained on the eccentric bushing do counterclockwise revolution, planetary revolution makes its clockwise rotation, the planetary gear of rotation is when revolution clockwise, drive driven gear counter-rotating with its engagement, thereby driven gear drive output shaft is done to be rotated counterclockwise, output shaft then drives joining with it straw screen or mat roll bar and does and be rotated counterclockwise, thereby realizes that straw screen or mat rolls action; When needs put down straw screen or mat, motor reel is done be rotated counterclockwise, by reducing gear described in the utility model, the joining with it straw screen or mat roll bar of output shaft drive is done turned clockwise, thereby straw screen or mat is put down; Reducing gear described in the utility model, can obtain bigger gearratio, can realize the self-locking of transmission system, after being rolled onto the precalculated position, cut off the electricity supply, electromotor stops operating, and greenhouse curtain-rolling machine can be parked in the precalculated position by the self-locking of transmission system, so just can finish the repertoire of greenhouse curtain-rolling machine.

Because the utility model taked said structure, simplified the design of greenhouse curtain-rolling machine reducing gear, improved the reliability of the utility model part processing, assembly process process, braking ability, and easy to maintenance, manufacturing cost is low.

Description of drawings

Accompanying drawing is the main cutaway view of an embodiment of the present utility model.

Embodiment

The utility model will be further described below in conjunction with accompanying drawing, motor gear 19 is assemblied on the motor reel by a flat key 20 and a holding screw 21, with driving gear 18 engagements, driving gear 18 is assemblied on the driving shaft 9 by rectangular spline and a shaft block ring 26, driving shaft 9 is assemblied on gear chamber 14 and the output shaft 5 by two bearings 6 and a bearing 17, eccentric bushing 11 is assemblied on the driving shaft 9 by rectangular spline, planetary gear 10 is by a shaft block ring 31, two holes are assemblied on the eccentric bushing 11 with back-up ring 30 and two bearings 8, and respectively with ring gear 13, driven internal gear 2 engagements, balance weight 12 is assemblied on the driving shaft 9 by a flat key 27, ring gear 13 is by 6 bolts 15,6 spring washers 16,6 straight pins 32 are assemblied on gear chamber 14 and the casing 1, driven internal gear 2 is by rectangular spline and a shaft block ring 33, a bearing 7 is assemblied on casing 1 and the output shaft 5, output shaft 5 passes through rectangular spline, a shaft block ring 3, a bearing 4 is assemblied on driven internal gear 2 and the casing 1, gear chamber cover 22 is by 4 bolts 23,4 spring washers 24 are assemblied on the electromotor 25, gear chamber cover 22 is by 6 bolts 28,6 spring washers 29 are assemblied on the gear chamber 14, and gear chamber 14 is by 6 bolts 15,6 spring washers 16 are assemblied on the casing 1.When motor reel turns clockwise, drive motor gear 19 is also done and is turned clockwise, 18 of the driving gears that is engaged with are done and are rotated counterclockwise, driving gear 18 drive driving shafts 9 and eccentric bushing 11 are done and are rotated counterclockwise, driving driven internal gear 2 by planetary gear 10 does and is rotated counterclockwise, planetary gear 10 drive output shafts 5 are done and are rotated counterclockwise, fixing ring gear 13 makes the planetary gear 10 that is contained on the eccentric bushing 11 do counterclockwise revolution, planetary gear 10 every public affairs turn around, the tooth pitch of N tooth is changeed in its rotation more, then planetary gear 10 revolution make its clockwise rotation, the planetary gear 10 of rotation is when revolution clockwise, drive driven gear 2 counter-rotatings with its engagement, thereby driven gear 2 drive output shafts 5 are done to be rotated counterclockwise, the joining with it straw screen or mat roll bar of 5 drives of output shaft is done and is rotated counterclockwise, thereby the realization straw screen or mat is rolled action; Owing to by the small teeth number difference planet gear transmission, can obtain bigger gearratio, can realize the self-locking of transmission system, when roller shutter, after being rolled onto the precalculated position, cut off the electricity supply, electromotor 25 stops operating, and greenhouse curtain-rolling machine can be parked in the precalculated position by the self-locking of transmission system; When needs put down straw screen or mat, motor reel is done to be rotated counterclockwise, do with 18 of the driving gears of motor gear 19 engagement and to turn clockwise, driving gear 18 drives eccentric bushing 11 and planetary gear 10 is done clockwise revolution, the driven internal gear 2 of planetary gear 10 drives of rotation is done and is turned clockwise counterclockwise, driven internal gear 2 drive output shafts 5 are done and are turned clockwise, the joining with it straw screen or mat roll bar of 5 drives of output shaft is done and is turned clockwise, thereby straw screen or mat is put down, so just realized rolling straw screen or mat and put down whole actions of straw screen or mat, finished the repertoire of greenhouse curtain-rolling machine.
