Abstract
The invention discloses a force increment belt pulley and relates to accessories of sun-shading roller shutter windows. The force increment belt pulley comprises a belt pulley shell and an output shaft. The belt pulley shell is arranged on the output shaft through a clamping spring and rotates around the output shaft. A base installation groove is formed in the belt pulley shell. A circular belt pulley gear is arranged on the belt pulley shell and located in the base installation groove. A circular output shaft gear is arranged on the output shaft and located in the base installation groove. An annular base is further arranged in the base installation groove. A supporting shaft is integrally arranged on the base. A duplex gear is arranged on the supporting shaft. Axial movement of the duplex gear is prevented through an upper cover. Big teeth of the duplex gear are engaged with the belt pulley gear, and small teeth of the duplex gear are engaged with the output shaft gear. A first shaft ring is arranged between the output shaft and the base. A second shaft ring is arranged between the output shaft and the belt pulley shell. Through the engaged rotation of the big gear and the small gear, force for operating an outer sun-shading roller shutter is decreased according to a gear engagement type speed decrement and torque increment principle, and operating convenience is improved for users.
Description
Technical field
The present invention relates to the accessory of sunshade roll-up window, particularly relate to the structure of the belt pulley driving curtain sheet lifting.
Background technique
The belt pulley that aluminum current alloy external roller blind is generally applied, for general plastic construction, manually or electronic drive unit drive, thus realize driving anistree tubular axis to rotate the lifting of external sunshade, run into the window that size is larger, steering force needed for driving can be very large, is unfavorable for the operation of user, may cause the discontented of user operation.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of reinforcement belt pulley is provided, by gears meshing, realize deceleration increment, reduce the use steering force of external roller blind.
The object of the present invention is achieved like this: a kind of reinforcement belt pulley, comprise belt pulley housing and output shaft, described belt pulley housing is arranged on output shaft by jump ring, and around output shaft rotation, belt pulley housing arranges floor installation groove, belt pulley housing in floor installation groove is arranged a circle belt pulley gear, output shaft is arranged a circle output shaft gear, output shaft gear is arranged in floor installation groove; In described floor installation groove, also annular base is set, base is wholely set back shaft, back shaft and output shaft be arranged in parallel, back shaft arranges duplicate gear, duplicate gear prevents duplicate gear axially mobile by upper cover, the canine tooth of duplicate gear is meshed with belt pulley gear, and the little tooth of duplicate gear is meshed with output shaft gear; First blowout patche is set between described output shaft and base, the second blowout patche is set between output shaft and belt pulley housing.
Back shaft on base of the present invention has four, and duplicate gear has four, and each duplicate gear is arranged on corresponding back shaft respectively, and the canine tooth of each duplicate gear is meshed with belt pulley gear respectively, and the little tooth of each duplicate gear is meshed with output shaft gear respectively.
The invention has the beneficial effects as follows: by the drive of drive unit, belt pulley gear engages with the canine tooth of four duplicate gears of all cloth of base portion and realizes rotating, the little tooth of four duplicate gears realizes engaging with output shaft gear simultaneously, by the engagement rotation of large small gear, according to gears meshing deceleration increment principle, thus realize the reduction of external roller blind steering force, improve the convenience of user operation.Four gears of all cloth engage simultaneously simultaneously, effectively reduce the power that each gear bears, reduce the mechanical property requirements of gear material, improve system reliability.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
As shown in Figure 1, be reinforcement belt pulley, comprise belt pulley housing 1 and output shaft 3, belt pulley housing 1 is fixed on output shaft 3 by jump ring 2, and rotates around output shaft 3.Belt pulley housing 1 arranges floor installation groove 9, and the belt pulley housing 1 in floor installation groove 9 is arranged a circle belt pulley gear 1-1, output shaft 3 is arranged a circle output shaft gear 3-1, output shaft gear 3-1 is arranged in floor installation groove 9.In floor installation groove 9, annular base 10 is also set, base 10 is wholely set four back shafts 5, every root back shaft 5 be arranged in parallel with output shaft 3 respectively, every root back shaft 5 arranges duplicate gear 4 respectively, each duplicate gear 4 prevents duplicate gear 4 from moving axially respectively by upper cover 6, the canine tooth 4-1 of each duplicate gear 4 is meshed with belt pulley gear 1-1 respectively, and the little tooth 4-2 of each duplicate gear 4 is meshed with output shaft gear 3-1 respectively.First blowout patche 7 is set between output shaft 3 and base 10, the second blowout patche 8 is set between output shaft 3 and belt pulley housing 1.
By the drive of drive unit, belt pulley gear 1-1 engages with the canine tooth 4-1 of the duplicate gear of four on base 10 4 and realizes rotating, the little tooth 4-2 of four duplicate gears 4 realizes engaging with output shaft gear 3-1 simultaneously, and output shaft 3 is fixed in the center hole of base 5 and belt pulley housing 1 by the first blowout patche 7 and the second blowout patche 8 and rotates.Designed by the meshing parameter of two-stage gear, realizing slowing down increases the effect of square.
