Abstract
The utility model relates to a reducer used for toothed chains which belongs to a fire disaster rescue apparatus and consists of a shell, a locating mechanism, a gear set and a non-return moment speed controller; each part like the shell and the locating mechanism is formed by adopting sheet metal forming technology. Slip elements in the non-return moment speed controller consist of an upper splint and a lower splint, a roller, a balance weight, and a fixing shaft; the sharp gears of riding wheels are changed into round wheel flanges with less quantity. The reducer has the characteristics of less abrasion and small heating of each transmission part during working.
Description
(1) technical field
The utility model is a kind of toothed chain decelerator, belongs to fire live-saving equipment.
(2) background technology
Decelerator in the disclosed this escape device of Chinese patent ZL200410013362.0 has adopted cast casing and nothing to return the moment speed regulator, relies on the engagement of detent mechanism and toothed chain, realizes the function that the high-rise life saving personnel can at the uniform velocity descend.Decelerator shell axis hole and speed regulator parts exist wearing and tearing big when work in the work, the fast defective of generating heat, and detent mechanism is to the guide effect instability of toothed chain, and the toothed chain shake is big.
The purpose of this utility model is that a kind of each drive disk assembly work of design is not easy to wear, heating is little, the toothed chain decelerator of detent mechanism reliable operation.
(3) summary of the invention
For achieving the above object, the utility model adopts following technical proposals, it is characterized in that: the decelerator shell, each parts of detent mechanism adopt the moulding of steel plate Sheet Metal Forming Technology, and by the Technology for Heating Processing stiffened, improve scuff resistance.Return the moment speed regulator by the nothing that ride wheel and slips are formed, slip element is formed with kit form, promptly form slip assemblies by last lower plate, roller, counterweight, fixed axis, slips adopts roller to replace with the turnover watt two ends of the wheel friction of riding, reduce impact wear, last lower plate middle part has axis hole, and slip assemblies directly is sleeved on the built-up gear elongated shaft of the second level, reduces the volume of decelerator and reduces positioning element.The pointed tooth of wheel of riding adopts the few circular wheel of quantity protruding, improve the impact strength and the anti-wear performance of the wheel of riding, the third level gear below fastening with the wheel of riding is fixed with fan, be used for the cooling of impact friction back and forth of speed regulator, ride wheel top is set with stage clip, the unlikely phenomenon that does not occur thereby conduct oneself with dignity downslide when being used for the engagement of decelerator and toothed chain.Three faces that detent mechanism contacts with toothed chain are embedded with the toothed chain guide plate, detent mechanism and outer casing underpart have groove and the guiding rivet are housed, be used to be slidingly connected, the locking plate below of adopting sliding axle to link with detent mechanism increases by a perforate, can be inserted on the reach, make that all there are two stress points on every limit between detent mechanism and the shell, thereby make connecting of decelerator and toothed chain stable.
After nothing in the decelerator is returned the slips in the moment decelerator and the wheel employing of riding the is such structure and profile, wear problem is resolved, and it is little to generate heat, the gearratio difference of wheel according to gear train of riding, the decrease speed difference, protruding can between three to six, the variation of circular wheel of the wheel of riding.
(4) description of drawings
Be described further below in conjunction with enforcement of the present utility model and accompanying drawing.
Fig. 1, be the utility model toothed chain with the assembling joint structure view of decelerator.
(5) specific embodiment
Toothed chain shown in Figure 1 returns the moment speed regulator with the decelerator main member by shell (1) detent mechanism (11), gear train, nothing and forms.First order built-up gear (2) is used for meshing with toothed chain, human body gravity is applied on the circular shaft of loading plate (10) below by safety belt, under the gravity effect, first order built-up gear (2), second level built-up gear (3), third level gear (8) is done speedup and is rotated, the wheel (7) of riding is fixed on third level gear (8) top, clockwise rotate, slip assemblies (4) is by last lower plate, roller (6), fixed axis (5), and counterweight is formed, last lower plate middle part has axis hole, by this axis hole, slip assemblies (4) is sleeved on the elongated shaft of second level built-up gear (3), when the wheel (8) of riding rotates, circular wheel protruding (b) successively with last two rollers of slip assemblies (4) (6) impact friction back and forth, then slip assemblies rocks from side to side, control gear group rotating speed is finished the control human body and is at the uniform velocity descended.Be fixed with fan in gear (8) below, the friction cooling of be used to ride wheel and slip assemblies, stage clip (9) is positioned at the wheel top of riding, and utilizes ride frictional force between wheel and shell of the elastic force increase of spring, makes the engagement of decelerator and toothed chain can be because of the deadweight downslide.Detent mechanism (11) contacts with toothed chain and all is embedded with the toothed chain guide plate on three, its below has gathering sill and the guiding rivet is housed with shell (1) bottom, horizontally slip for detent mechanism, be convenient to the engagement of decelerator and toothed chain, locking plate (14) below of adopting sliding axle (13) to link with detent mechanism increases perforate (a), when detent mechanism is finished decelerator and toothed chain engagement capability, depress locking plate (14), perforate (a) is inserted on the overhanging end of the reach (12) that is used for fixing loading plate (10), be inserted in respectively on the outrigger shaft of first order built-up gear axle and detent mechanism top in two holes, top, make detent mechanism and shell both sides stressed evenly, thereby make decelerator reliable and stable with connecting of toothed chain.
Claims (1)
1. toothed chain decelerator, by shell, detent mechanism, gear train and nothing are returned the moment speed regulator and are formed, it is characterized in that: the decelerator shell, each parts of detent mechanism adopt the moulding of steel plate Sheet Metal Forming Technology, and by the Technology for Heating Processing stiffened, return the moment speed regulator by the nothing that ride wheel and slips are formed, slip element is formed with kit form, promptly by last lower plate, roller, counterweight, fixed axis is formed slip assemblies, slips adopts roller to replace with the turnover watt two ends of the wheel friction of riding, last lower plate middle part has axis hole, the pointed tooth of wheel of riding adopts the few circular wheel of quantity protruding, the third level gear below fastening with the wheel of riding is fixed with fan, and three faces that detent mechanism contacts with toothed chain are embedded with the toothed chain guide plate.
