Abstract
The utility model discloses a transmission gear for a small elevator, which mainly comprises a motor, a belt pulley, a winding drum and a braking device, wherein a power shaft (1) and a drum shaft (2) arranged in parallel are arranged on the transmission gear, the belt pulley (3) at one end of the power shaft (1) is connected with the motor, a pinion (41) with a speed reducing gear pair is arranged at the other end of the power shaft (1), engaged gearwheels (42) are arranged on the outer side of the winding drum (5) on the drum shaft (2), and a brake band (6) is arranged on the inner side of the winding drum (5). In the utility model, the power shaft is parallel to the drum shaft, a speed reducing mechanism, a winding mechanism and a braking mechanism are arranged on the drum shaft at the same time, and as a straight gear parallel shaft is adopted to reduce speed. Therefore, the utility model has the advantages of high transmission efficiency, simple and compact structure, reasonable arrangement, reduction of size, light weight, low manufacturing cost, simple process and low processing cost.
Description
Technical field
The utility model relates to a kind of driving device of lift system, especially a kind of small-sized gig driving device.
Background technology
At present, domestic residential building, the finishing of office building, transport raw MAT'L in the decorative engineering, and grain etc. is transported in the rural area on the roof, often to use small-sized lifting elevating gear, some present small-sized machine structures are complicated, mainly comprise motor, drivings device such as speed reduction gearing, brake equipment, pulley, suspender, lifting rope, reel, work trestle etc., driving device adopts motor to pass through pulley drive more, driving external reel rotates, lifting rope connecting shackle on the reel promotes weight, speed reduction gearing is generally turbine, scroll-type, driving efficiency is low, has only 30-35%, each parts of driving device are rack-mount respectively, complex structure, arrange and disperse, cause mechanical dimension bigger, use inconvenience.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the above problems, provide a kind of simple in structure, arrange compact, easy and convenient to handle a kind of small-sized gig driving device.
The small-sized gig driving device of the utility model mainly comprises motor, belt pulley, reel, brake equipment, this driving device is provided with dynamical axis and the drum shaft that be arranged in parallel, the belt pulley of dynamical axis one end links to each other with motor, the dynamical axis other end is provided with the miniature gears of speed reducing gear pair, the big gear wheel that is meshed is located at the reel outside on the drum shaft, and the reel inboard is provided with brake collar.
As a kind of improvement of the present utility model, drum shaft is provided with nylon sleeve.
The beneficial effects of the utility model are: dynamical axis and drum shaft be arranged in parallel, and speed reduction gearing, hoisting mechanism and stop mechanism are set on the drum shaft simultaneously, slow down to adopt the straight-tooth gear parallel shafts to slow down, the efficient height can reach more than 75%, is about 1: 10 though reduction ratio hangs down, but for small-sized gig, enough use, whole transmission device is simple and compact for structure, connection and reasonable arrangement, and volume dwindles greatly, overall weight is light, low cost of manufacture, technology is simple, and tooling cost is low.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a right elevation shown in Figure 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the small-sized gig driving device of the utility model mainly comprises motor, belt pulley, reel, brake equipment, the principal organ of this driving device is two axles that be arranged in parallel, be dynamical axis 1 and drum shaft 2, dynamical axis 1 one ends are belt pulley 3, link to each other with the motor on being fixed on frame, complete machine power is provided, the other end of dynamical axis 1 is the miniature gears 41 of speed reducing gear pair.As shown in Figure 2, drum shaft 2 is parallel with dynamical axis 1 front and back, the setting that interlaces up and down, and reel 5 is positioned at the centre of drum shaft 2, and the big gear wheel 42 that is meshed with dynamical axis miniature gears 41 is contained in an end of drum shaft 2, brake equipment adopts the brake collar structure, and brake collar 6 is contained in the other end of drum shaft 2.In addition, owing on the drum shaft 2 speed reduction gearing, hoisting mechanism and stop mechanism are set simultaneously, stressed big, the supporting of employing bearing is worn and torn easily, volume is big, and the weight of bearing own is big, therefore, drum shaft 2 of the present utility model does not adopt the form of bearing supporting, and adopts nylon sleeve 7 transmissions.
The utility model can cooperate the various supports that have crossbeam, support arm etc. to use, motor is fixed on the support, and power is provided for the dynamical axis be fixed on the support by belt-driving, and dynamical axis drives the drum shaft rotation, and lifting rope one end is connected on the reel, the other end links to each other with suspension hook by track adjusting wheel, the commentaries on classics that brake handle is controlled reel by brake collar, brake cable stops, and is simple and compact for structure, and volume is little, overall weight is light, low cost of manufacture.
Claims (2)
1. small-sized gig driving device, mainly comprise motor, belt pulley, reel, brake equipment, it is characterized in that: this driving device is provided with the dynamical axis (1) and drum shaft (2) that be arranged in parallel, the belt pulley (3) of dynamical axis (1) one end links to each other with motor, dynamical axis (1) other end is provided with the miniature gears (41) of speed reducing gear pair, the big gear wheel that is meshed (42) is located at reel (5) outside on the drum shaft (2), and reel (5) inboard is provided with brake collar (6).
