Abstract
The utility model provides a transmission wheel driven by multiple groups of planet gear reducing systems. The transmission wheel is characterized in that two or more driving shafts are arranged on the same transmission wheel, wherein each driving shaft transmits the power to the transmission wheel by each independent gear reducing system to enable two or more parts of the transmission wheel to be subject to the driving force at the same time. The transmission wheel with the structure, on one hand, can reduce load of the original driving wheel reducing system and improve the safety factor of the gear reducing system by increasing one or more groups of driving devices based on the original driving device, and on the other hand, can adjust rotating speed of each wheel according to the requirement, avoid the serious wheel damage problem due to the enforced synchronization, and improve the operation safety.
Description
Technical field
The utility model relates to the power wheel technology.
Background technology
The load-carrying demand of large-scale mine car is all very big, reaches the hundreds of ton, and the diameter of geared wheel and width are all very big usually, and be very high to the performance requriements of gear reduction system.Existing technology, every group of geared wheel has only a power, and the transmission of power can only drive the power wheel rotation through a gear reduction system.This technology, the area of contact of sun wheel gear and planet gear wheel and planet pinion gear and gear ring is all less on the one hand, and the extent of deterioration of gear reduction system is big, and the safety factor of gear reduction system is not high; On the other hand, general power wheel is combination wheel, the synchronized operation by force of the nearside wheel of wheel and off-side wheel.Especially at Ackermann steer angle, because nearside wheel and off-side wheel range ability are different, so require the rotating speed of nearside wheel and off-side wheel different, because existing technology can't realize the differential operation, will accelerate the wheel wearing and tearing so again.
Summary of the invention
The purpose of this utility model provides a kind of geared wheel that is driven by many groups planetary gear reduction system, has reduced the load of former driven wheel deceleration system, has improved the safety factor of gear reduction system, has guaranteed safe in operation.
The technical scheme that realizes the utility model purpose is: a kind of geared wheel that is driven by many groups planetary gear reduction system, described gear reduction system comprises sun wheel, satellite gear, internally toothed annulus, it is characterized in that being provided with two or more axle drive shafts on the same group of geared wheel, each axle drive shaft is given geared wheel through gear reduction system independently with transmission of power.
Wherein the power that connects of axle drive shaft is from the wheel outside or from the electrical motor of inside wheel, or both exist simultaneously; Described power is one, two or more.
Wherein the gear reduction system that is connected respectively with each axle drive shaft is single-stage or multistage.
Wherein every group of geared wheel assembled one, two or more wheel hub.
Wherein each wheel hub connects one, two or more gear reduction system.
The utility model has increased one or more groups actuating device on former actuating device basis on the one hand, has reduced the load of former driven wheel deceleration system, has improved the safety factor of gear reduction system; Can adjust the rotating speed of each wheel on the other hand as required, avoid having improved safe in operation because of the synchronous wheel well damage problem that causes by force.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, geared wheel is built-up wheel, and this built-up wheel is combined by inside tire, outside tire.Electrical motor 4A is positioned at electric wheel inside center position, and electrical motor 4B is positioned at the mining car back axle of electric drive wheel place.During electrical motor 4A work, the axle drive shaft 1 of electrical motor 4A connects sun wheel 2, sun wheel 2 drives the satellite gear big gear wheel 4 with its engagement, planet wheel spindle 3 rotates with planet pinion gear 5 thereupon, planet pinion gear 5 drives the internally toothed annulus 6 that is engaged with, internally toothed annulus 6 rotates, and drive the wheel hub 7 that is connected with outside tire, and then outside tire is driven; During electrical motor 4B work, the axle drive shaft 1 of electrical motor 4B connects sun wheel 2, sun wheel 2 drives the satellite gear big gear wheel 4 with its engagement, planet wheel spindle 3 rotates with planet pinion gear 5 thereupon, planet pinion gear 5 drives the internally toothed annulus 6 that is engaged with, internally toothed annulus 6 rotates, and drive the wheel hub 7 that is connected with inside tire, and then inside tire is driven.Parameters such as the model of two electrical motor 4A and 4B, power, rotating speed can be identical, also can be different; Being connected respectively with each axle drive shaft, by the gear reduction system that sun wheel, satellite gear, internally toothed annulus etc. constitute, can be single-stage, also can be multistage; With the supporting wheel net of gear reduction system, bearing etc., can be identical, also can be different; Every group of geared wheel can be assembled a wheel hub, also can assemble two or more wheel hubs; Each wheel hub can connect a gear reduction system, also can connect two or more gear reduction system.
Need to prove: technology in the past, the electrical motor 4 in the electric wheel have only a single-ended outputting power of axle drive shaft, through the set of gears deceleration system power is passed to wheel, thereby the medial and lateral tire of geared wheel can only be synchronous by force.
Need to prove: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that previous embodiment is put down in writing, and perhaps part technical characterictic is wherein replaced on an equal basis.
All within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
