Abstract
The utility model relates to a driving device, in particular to a driving device of a door closer, which comprises a bearing block. A bearing cap is arranged at the upper end of the bearing block, a plurality of bearings are arranged on the inner wall of the bearing block, a bevel gear is sleeved into the bearing block and tightly connected with the bearings, a reduction box is arranged at the lower end of the bearing block, a plurality of pins are arranged at the lower end of the bevel gear, gears fixedly connected to the pins are connected with a driving gear in the reduction box. The bevel gear is directly driven to rotate under driving of the reduction gear, so that the driving device is more reliable in structure and higher in stability.
Description
Technical field
The utility model relates to a kind of drive unit, relates in particular to a kind of drive unit of door closer.
Background technology
Along with society is fast-developing, door closer is extensive use of on society.Need to use helical gear in the drive unit in door closer, existing helical gear and reducer output shaft are divided into two parts, link together by pin or other modes.Such form structure is compact inadequately, and door closer is less stable in running.
Summary of the invention
In order to address the above problem, the utility model provides a kind of good stability, and the utility model provides helical gear and reducer output shaft is an one, the more reliable door closer drive unit of structure.
To achieve these goals, the utility model is mainly solved by the following technical programs: a kind of drive unit of door closer, comprise bearing support, the upper end of bearing support is provided with bearing cover, the inside wall of bearing support is provided with several bearings, be socketed with helical gear in the bearing support, helical gear closely is connected with described bearing, the lower end of described bearing support is provided with reduction box, described helical gear lower end is provided with several pins, be fixedly connected with gear on the pin, the driven wheel in gear and the described reduction box is connected.
As preferably, above above-mentioned bearing, be provided with nut, nut sleeve is connected on the described helical gear, is provided with screw hole in the described nut, and screw hole is provided with screw b.
Because the utility model drives helical gear and rotates directly by the transmission of reduction gearing, this spline structure is more reliable, and stability is higher.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Below in conjunction with accompanying drawing 1-2, the specific embodiment of the technical solution of the utility model is described in further detail.
Embodiment: a kind of drive unit of door closer, comprise bearing support 7, the inside wall of bearing support 7 is provided with several bearings 8, bearing support 7 lower ends are provided with stepped hole, prevent that bearing from down going here and there, and the upper end is provided with bearing cover 3, prevent up transmission of bearing 8, bearing 8 endoporus cooperate with helical gear 1.The lower end of bearing support 7 is provided with reduction box 5, and bearing support 7 and reduction box 5 interconnect by the screw a9 of both sides.The upper end of helical gear 1 is provided with screw thread, by with being connected of nut 2, prevent that helical gear from down going here and there, the lower end is provided with step and cooperates with bearing, prevent up transmission of helical gear, and be provided with several pins 4, and pin is fixedly connected with gear 6 on 4, and gear 6 and described reduction box 5 interior driven wheels 12 match.Be provided with screw hole 11 in the nut 2, screw hole 11 is provided with screw b10.
When the utility model is worked, electric motor starting, after reduction box 5 decelerations, driven wheel 12 driven gears 6 in the reduction box 5 rotate, thereby helical gear 1 rotates, driver part in addition in helical gear 1 and this device is connected, this driver part with on connecting rod be connected closing and opening of driving gate.Helical gear 1 rotates and drives the running that realizes this driver part.
