Abstract
The utility model discloses a can install at epaxial reduction gear, including drive shaft and steel bushing, be provided with the internal gear in the steel bushing, offered the external gear with internal gear matched with in the drive shaft, internal gear and outer gear engagement are provided with the elastic power transmission that has who is connected with the load and take on the steel bushing, and the diameter that drives epaxial external gear is lighter than the diameter of internal gear, the utility model discloses make the drive shaft setting in the steel bushing, it can practice thrift 40% space, makes the volume of lathe or other devices dwindle greatly, just so can practice thrift the space at to a great extent, the problem of a plurality of spool reduction gear is leaded to because operational environment is narrower and small being unfavorable for installing is solved, simultaneously because the utility model discloses simple structure installs convenient to use, and is further, also can reduce the cost of equipment.
Description
[technical field]
The utility model belongs to mechanical field, is specifically related to a kind of speed reduction unit can being arranged on axle.
[background technology]
Along with the development of machinery industry, all kinds of mechanism is widely used in life, facilitates to very big limit our life. In variator field, the novelty of mechanism also improves greatly, and direction to lightweight and miniaturization is developed gradually. Such as, nowadays various speed reduction unit is used in the device such as automobile, lathe, and object is to change rotating speed and the torque that propulsion source exports, it is achieved the efficient utilization of power. In these devices, speed reduction unit generally to be engaged each other by the gear of different size and realize speed change. And general single-stage speed reducing device, generally all need the gears meshing of two different sizes and the number of teeth to realize slowing down and increasing moment of torsion. The principle of this kind of speed reduction unit needs a drive shaft and driving toothed gear as Power output end, and a driven shaft and follower gear are meshed as power intake, driving toothed gear and follower gear, so needing two parallel installations of axle, occupy huge space. Under some specific Working environments, there will be the situation of unsuitable design and installation.
[practical novel content]
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of speed reduction unit can being arranged on axle, it is possible to be directly installed on drive shaft, it is possible to reduce the volume of speed reduction unit, it is easy to install less Working environment simultaneously, and by belt, moment of torsion is passed to driven member.
In order to achieve the above object, the utility model comprises drive shaft and steel bushing, internal wheel it is provided with in steel bushing, drive shaft is offered the outer rotor matched with internal wheel, internal wheel engages with outer rotor, steel bushing is provided be connected with load there is elastic power belt, the diameter of the outer rotor on drive shaft is less than the diameter of internal wheel.
Described power belt adopts belt.
The both sides of described steel bushing are provided with end cap.
Described drive shaft is provided with the axle collar that can be fixed on steel bushing by end cap.
Outer rotor on described drive shaft is fixing on the driving shaft by key.
Described internal wheel and outer rotor all adopt rectangle gear.
It is provided with lubrication accessory between the described axle collar and end cap or it is coated with lubricating oil.
Compared with prior art, the utility model makes drive shaft be arranged in steel bushing, and it can save the space of 40%, and the volume of lathe or other devices is reduced greatly, so just can save space to a great extent; Solve the problem causing being unfavorable for installing the speed reduction unit of multiple axle because Working environment is narrower and small, simultaneously owing to the utility model structure is simple, easy to install, further, it is also possible to reduce the cost of equipment.
[accompanying drawing explanation]
Fig. 1 is the structural representation in the utility model front;
Fig. 2 is the structural representation of the utility model reverse side;
Fig. 3 is the structural representation that the utility model is overlooked.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1 and Fig. 2, comprise drive shaft 4 and steel bushing 1, internal wheel 2 it is provided with in steel bushing 1, drive shaft 4 is offered and the outer rotor that internal wheel 2 matches, internal wheel 2 engages with outer rotor, steel bushing 1 is provided be connected with load there is elastic power belt, the diameter of the outer rotor on drive shaft 4 is less than the diameter of internal wheel 2.
The both sides of steel bushing 1 are provided with end cap 7, drive shaft 4 is provided with the axle collar 6 that can be fixed on steel bushing 1 by end cap 7, outer rotor on drive shaft 4 is fixed on drive shaft 4 by key, internal wheel 2 and outer rotor all adopt rectangle gear, be provided with lubrication accessory or be coated with lubricating oil between the axle collar 6 and end cap 7.
Preferably, power belt adopts belt 5.
As shown in Figure 3, when speed reduction unit operates time, the trend that its You Shi mechanism rotates around axis Y-Y with drive shaft 4, this kind of eccentric trend rotated is offset by the pulling force of belt 6, this pulling force and end cap 7 can only rotate around axis Z-Z what steel bushing 1 limited, drive shaft 4 rotates another effect of trend around axis Y-Y, is the tension force making belt 6 can keep enough.
If needing to make this device fix, it is possible to install a sway brace from certain of frame additional toward an end cap 7.
