Abstract
The utility model discloses a roller shutter door and belongs to the field of mechanical equipment. The roller shutter door comprises a motor, a motor gear connected with the motor, a roller shutter shaft gear connected with the motor gear through a chain, a first bearing with a seat, a roller shutter shaft connected with the first bearing with the seat, a second bearing with a seat, and a travel limiting stopper connected with the second bearing with the seat, wherein the first bearing with the seat is connected with the roller shutter shaft gear, and the second bearing with the seat is connected with one end of the roller shutter shaft. According to the roller shutter door, a chain transmission structure is adopted, an improved roller shutter door system can adapt to various environments and conditions, debugging and maintenance are facilitated, the using rate and the generality of the roller shutter door are improved, various using demands can be met, and the system is stable and reliable in operation.
Description
Technical field
The utility model relates to plant equipment field, particularly a kind of rolling door.
Background technology
Rolling door of the prior art, referring to Fig. 1, this structure is relatively simple, and motor output shaft is directly connected with roller shutter door-hinge by shaft coupling, and motor output shaft rotational speed N 1 equals roller shutter door-hinge rotational speed N 2.
Suppose: roller shutter cloth lifting height is L(mm); Curtain rolling shaft diameter is D(mm); Motor speed is N1(r/s); Curtain rolling shaft rotating speed is N2(r/s).
There is following derivation:
1. roller shutter cloth rises to top, and curtain rolling shaft rotates the number of turns and is:
2. the roller shutter cloth rise time is: T (s)=H
n2
Because N1=N2, so
So roller shutter cloth rise time
By above-mentioned derivation formula, can be drawn: in direct coupled structure, the roller shutter cloth rise time is determined by motor speed N1 and two parameters of rolling door diameter D.So adjust the rise time as needed, can change this two parameters, but consider cost and actual conditions, conventionally only change curtain rolling shaft and change the rise time.
To sum up analyze and known in conjunction with actual service condition: direct coupled structure is in debugging with while safeguarding, not only inefficiency, wastes time and energy, and debugging and maintenance cost high, use rate variance, versatility is low.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind of and has been convenient to debugging and safeguards, has improved utilization rate and the versatility of rolling door, can meet various user demands, and the reliable rolling door of system run all right.Described technical scheme is as follows:
The utility model embodiment provides a kind of rolling door, and described rolling door comprises motor, the motor gear being connected with described motor, the curtain rolling shaft gear being connected with described motor gear by chain, the first rolling bearing units that are connected with described curtain rolling shaft gear, the curtain rolling shaft being connected with described the first rolling bearing units, the second rolling bearing units that are connected with described curtain rolling shaft one end, the range limiter being connected with described the second rolling bearing units.
Particularly, described curtain rolling shaft one end is provided with described the second rolling bearing units, and the other end is provided with described the first rolling bearing units.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
Use chain drive structure, make the rolling door system after improving can adapt to various environment and condition, be convenient to debugging and safeguard, improved utilization rate and the versatility of rolling door, can meet various user demands, and system run all right is reliable.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of rolling door of the prior art;
Fig. 2 is the structural representation of the rolling door that provides of the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment
The utility model embodiment provides a kind of rolling door, referring to Fig. 2, described rolling door comprises motor 1, the motor gear 2 being connected with motor 1, the curtain rolling shaft gear 4 being connected with motor gear 2 by chain 3, the first rolling bearing units 5 that are connected with curtain rolling shaft gear 4, the curtain rolling shaft 6 being connected with the first rolling bearing units 5, the second rolling bearing units 8 that are connected with curtain rolling shaft 6 one end, the range limiter 7 being connected with the second rolling bearing units 8.
Particularly, curtain rolling shaft 6 one end are provided with the second rolling bearing units 8, and the other end is provided with the first rolling bearing units 5.
Used chain drive structure, motor is connected with curtain rolling shaft by chain, and motor output shaft and curtain rolling shaft are installed respectively gear Z1 and the Z2 of two kinds of different numbers of teeth.So this kind of structure is equivalent to an easy speed change system.
Suppose: roller shutter cloth lifting height is L(mm); Curtain rolling shaft diameter is D(mm); Motor speed is N1(r/s); Curtain rolling shaft rotating speed is N2(r/s); The motor gear number of teeth is Z1; The curtain rolling shaft gear number of teeth is Z2.
There is following derivation:
1. roller shutter cloth rises to top, and curtain rolling shaft rotates the number of turns and is:
2. by plane ordinary gear train gearratio formula:
In system, motor gear is driving wheel, and curtain rolling shaft gear is driven pulley, so have:
3. roller shutter cloth rise time
So roller shutter cloth rise time
By above-mentioned derivation formula, can be drawn: in this kind of structure, the roller shutter cloth rise time is by curtain rolling shaft diameter D; Motor gear tooth number Z 1; Curtain rolling shaft gear number of teeth Z2 and motor speed N1 determine.Therefore, carry out criterion and quantity, by curtain rolling shaft standardization, in the system after standardization, rise time T is only relevant with curtain rolling shaft gear with motor gear.During debugging maintenance, only need to change corresponding gear, reduce debugging cost and cycle, improved utilization rate and the versatility of system, can meet various user demands.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
Use chain drive structure, make the rolling door system after improving can adapt to various environment and condition, be convenient to debugging and safeguard, improved utilization rate and the versatility of rolling door, can meet various user demands, and system run all right is reliable.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
