Abstract

The utility model relates to a mechanical drive device, and particularly relates to a one-way transcending gear case. An input shaft is arranged on a case body; a motor is arranged at one end of the input shaft; the other end of the input shaft is arranged inside the case body and provided with a primary pinion; a primary rack wheel is meshed with the primary pinion; a secondary pinion is arranged on a gear shaft of the primary rack wheel; a secondary rack wheel is meshed with the secondary pinion, and the movement direction is changed; the secondary rack wheel is arranged on the gear shaft of a three-level pinion; the three-level pinion is meshed with an outer ring gear, and meanwhile, the movement direction of the outer ring gear is also changed; an output shaft is arranged inside an inner hole of the outer ring gear; and an inner ring, a keeping ring subassembly and a bearing are orderly arranged between the output shaft and the outer ring gear. The one-way transcending gear case has the advantages of less connectors, compact structure, low cost and long service life, and is simple to maintain and convenient and reliable to install; and a one-way clutch and the gear case are merged into a whole. The one-way transcending gear case is especially suitable for mechanical drive.

Description

The mono-directional overrun gear-box
(1) technical field
The utility model relates to a kind of mechanical transmission, specifically a kind of mono-directional overrun gear-box.
(2) background technique
The drive units such as present noria, Belt Conveyors generally are comprised of main gear reducer and helper drive gear-box.The effect of helper drive gear-box is that main motor quits work in the situation, drives whole system with lower rotating speed and slowly moves, with convenient maintenance or adjust.In when normal operation, burn out for avoiding main gear reducer oppositely to drive the helper drive motor rotation, generally be connected with main gear reducer at the helper drive gear-box and connect with free wheel device.But because link is many, machining accuracy is poor, and the reason such as on-the-spot installation conditions is poor, can't guarantee the installation precision of free wheel device, cause the very fast damage of free wheel device, make enterprise suffer very large economic loss.
(3) model utility content
The purpose of this utility model is to provide a kind of link few, compact structure, easy for installation, reliability is high, maintenance is simple, a kind of mono-directional overrun gear-box of the low long service life of cost.
For achieving the above object, implementation of the present utility model is: the utility model is by motor, casing, the one-level small gear, the one-level gearwheel, the secondary small gear, the secondary gearwheel, three grades of small gears, outer ring gear, bearing, output shaft forms, it is at casing input shaft to be housed, one end of input shaft is provided with motor, the other end is located in the casing and on it one-level small gear is installed, what be meshed with the one-level small gear is the one-level gearwheel, gear shaft at the one-level gearwheel is equipped with the secondary small gear, the secondary gearwheel not only is meshed with the secondary small gear and has changed moving direction, the secondary gearwheel is installed on the gear shaft of three grades of small gears, three grades of small gears are meshed with outer ring gear, also changed simultaneously the moving direction of outer ring gear, in the endoporus of outer ring gear output shaft is arranged, between output shaft and outer ring gear, be provided with successively interior ring, keep coil assembly and bearing.
The utility model has the advantage of: link is few, and compact structure is easy for installation, reliability is high, maintenance is simple, and cost is low, long service life; It unites two into one overrunning clutch and gear-box, combine together.It is particularly suitable for using in mechanical transmission.

(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The utility model is by motor, casing, the one-level small gear, the one-level gearwheel, the secondary small gear, the secondary gearwheel, three grades of small gears, outer ring gear, bearing, output shaft forms, the utility model is at casing (2) input shaft to be housed, one end of input shaft is provided with motor (1), the other end is located in the casing and on it one-level small gear (3) is installed, what be meshed with one-level small gear (3) is one-level gearwheel (4), gear shaft at one-level gearwheel (4) is equipped with secondary small gear (5), secondary gearwheel (6) not only is meshed with secondary small gear (5) and has changed moving direction, secondary gearwheel (6) is installed on the gear shaft of three grades of small gears (12), three grades of small gears (12) are meshed with outer ring gear (7), also changed simultaneously the moving direction of outer ring gear (7), output shaft (11) is arranged in the endoporus of outer ring gear (7), between output shaft (11) and outer ring gear (7), be provided with successively interior ring (8), keep coil assembly (9) and bearing (10).Overrunning clutch kernel by outer ring gear (7), interior ring (8), maintenance coil assembly (9) and bearing (10) form has the function that the forward transmitting torque oppositely surmounts.
The power process tertiary gear deceleration of the middle motor (1) of mono-directional overrun gear-box (2) is passed on the outer ring gear (7) during work, outer ring gear (7) is passed to interior ring (8) to power by the overrunning clutch kernel of wedging state, by output shaft (11) power is exported at last.When output shaft (11) was inputted as power, the overrunning clutch kernel was in and surmounts state, and power can't pass to the upper level gear, thus protection motor (1).
Owing to the supporting role of bearing (10), guarantee the concentricity of outer ring gear (7) and interior ring (9) fully, the free wheel device kernel can fully be exerted oneself, thus can the selection of small free wheel device in the identical situation of moment of torsion.

Claims (1)

1. mono-directional overrun gear-box, by motor, casing, the one-level small gear, the one-level gearwheel, the secondary small gear, the secondary gearwheel, three grades of small gears, outer ring gear, bearing, output shaft forms, it is characterized in that at casing (2) input shaft being housed, one end of input shaft is provided with motor (1), the other end is located in the casing and on it one-level small gear (3) is installed, what be meshed with one-level small gear phase (3) is one-level gearwheel (4), gear shaft at one-level gearwheel (4) is equipped with secondary small gear (5), secondary gearwheel (6) not only is meshed with secondary small gear (5) and has changed moving direction, secondary gearwheel (6) is installed on the gear shaft of three grades of small gears (12), three grades of small gears (12) are meshed with outer ring gear (7), also changed simultaneously the moving direction of outer ring gear (7), output shaft (11) is arranged in the endoporus of outer ring gear (7), between output shaft (11) and outer ring gear (7), be provided with successively interior ring (8), keep coil assembly (9) and bearing (10).
