Abstract
A double-gear box combined speed reducer with the slow transmission function. The utility model is characterized in that a double-end input and single-end output are arranged on the main gear box, an auxiliary motor and an auxiliary gear box driven by the auxiliary motor are arranged, the input axle at one end of the double-end input axle of the main gear box is linked with the output axle of the main motor, and the input axle at the other end is linked with the output axle of the auxiliary gear box through an overrunning clutch. The utility model can output two different transmission ratios on the identical output axle on one speed reducer through the synergetic work of the main motor and the auxiliary motor. The utility model satisfies the different speed requests under the two different states-normal running and installation inspection. The slow transmission function can enable the debugging process of the device such as the hopper type hoisting device to be more convenient, more reliable and more secure.
Description
Technical field:
The utility model relates to retarder.
Background technique:
Retarder is widely used for device driver system.Desirable retarder should have that reliability height, transmission power are big, good seal performance, little, characteristics such as noise is little, good heat dissipation, installation form are flexible take up room.Traditional speed reducer has only a gear-box usually, can only correspondingly export a speed ratio on its output shaft, is used for the normal operation of equipment.There is such problem in concrete the use, some special equipment, special occasion not only require retarder that normal equipment operation speed can be provided, simultaneously, also require speed reducer to have slow transmission agency, with the needs of installation, debugging and the maintenance of satisfying driven equipment.But the retarder of above-mentioned conventional construction does not possess this function.With the noria is example, promotes traction piece (adhesive tape or chain) accurate location piecemeal in order to realize bucket type, with the assembling that makes things convenient for hopper, be convenient to observe seek and need maintenace point, and makes and needs maintenace point be accurately positioned in maintenance department, and slow transmission agency is essential.
Summary of the invention:
Technical problem to be solved in the utility model is to avoid above-mentioned deficiency of the prior art, and a kind of bidentate roller box combination retarder with slow transmission agency is provided.On the same output shaft of a retarder, export two different speed ratios, to satisfy the friction speed demand under the different conditions such as normal operation of equipment and installation maintenance.
The technological scheme that the utility model technical solution problem is adopted is:
The utility model comprises main-gear box.
Structural feature of the present utility model is that described main-gear box is set to both-end input and single-ended output, and the auxilliary gear-box that auxiliary motor is set and drives by auxiliary motor, in the both-end input shaft of described main-gear box, one end input shaft and main motor output shaft interlock, the other end input shaft is by free wheel device and the interlock of auxilliary gearbox output shaft.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model can be exported two different speed ratios by the collaborative work of main motor and auxiliary motor on same output shaft of a retarder.Friction speed demand when overhauling two kinds of different conditions to satisfy normal operation of equipment and installation.The utility model is applied in the equipment such as noria, can realizes the accurate location piecemeal of traction pieces such as noria adhesive tape or chain, be very easy to the assembling of hopper.When overhaul of the equipments, can set slow transmission, make the traction piece slow running, being convenient to observe seek needs maintenace point, and can make and need be accurately positioned in the access door place by maintenace point.The debug process that slow transmission agency of the present utility model can make noria is more convenient reliable, safer.
2, the utility model is simple in structure, cost is low, and is easy to implement.
The drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is auxilliary gear-box of the utility model and free wheel device cooperating structure schematic representation.
Fig. 3 is the utility model free wheel device internal structure schematic representation.
Embodiment:
Referring to Fig. 1, Fig. 2, present embodiment includes main-gear box 1, shown in the figure, main-gear box 1 is set to both-end input and single-ended output, and the auxilliary gear-box 3 that auxiliary motor 2 is set and drives by auxiliary motor 2, in the both-end input shaft of main-gear box 1, an end input shaft 4 and main motor output shaft interlock, the other end input shaft 5 is by output shaft 11 interlocks of free wheel device 6 with auxilliary gear-box 3.
Referring to Fig. 2, Fig. 3, free wheel device 6 is made of outer ring 7 with overdrive clutch structure and inner ring 8, and wherein outer ring 7 connects firmly with main-gear box input shaft 5, and inner ring 8 connects firmly with the output shaft 11 of auxilliary gear-box 3.Outer ring 7 and inner ring 8 are rotating component, are counterclockwise shown in the sense of rotation figure.When outer ring 7 rotated counterclockwise, inner ring 8 was held tightly owing to being pressed into of spring ratchet 9, and at this moment, inner ring 8 does not rotate; And when inner ring 8 rotated counterclockwise, under the drive of ratchet 9, rotated thereupon outer ring 7.
Specifically working method is, when driven equipment normally moved, the outer ring 7 of free wheel device was owing to the rotation of driving component in the main-gear box 3 is rotated, and ratchet 9 is pressed into, and inner ring 8 is thrown off with the outer ring, and inner ring 8 does not rotate.At this moment, main-gear box 1 is with the speed ratio i of main-gear box self
1Driving arrangement runs well; When the slow transmission of needs, close down main motor, starting auxiliary motor 2, auxilliary gear-box 3 is with speed ratio i
2Drive free wheel device inner ring 8 and rotate, because the effect of elasticity ratchet 9, inner ring 8 and outer ring 7 closures are rotated simultaneously by inner ring 8 and outer ring 7 that the output shaft 11 of assisting gear-box 3 drives free wheel device, and promptly auxilliary gear-box 3 and main-gear box 1 are worked simultaneously.At this moment, the output speed ratio of main-gear box output shaft 10 is i
1* i
2The speed ratio of assisting gear-box 3 can be designed to i
2＞10.Therefore, the rotating speed of driven equipment has slowed down more than 10 times.
In concrete the enforcement, the retarder backward rotation problem in order to prevent to occur can be provided with non-return device 12 on gear-box.
