Abstract
The utility model discloses a low backlash planet-gear speed reducer, particularly a speed reducer. The utility model adds a shaft coupling (1) on the basis of an existing speed reducer; the shaft coupling (1) and a first level sun wheel shaft (16) of the speed reducer (J) can be integrally integrated. More specifically, a back flange (17), the shaft coupling (1), the first level sun wheel shaft (16), a first level sun wheel (3), a middle planetary frame (6), a secondary sun wheel (15) and an output shaft (13) are orderly arranged on the central shaft line of a box body from left to right and are orderly mutually connected, wherein a first level planetary wheel (4) is engaged with the first level sun wheel (3); a secondary planetary wheel (10) is engaged with the secondary sun wheel (15). The utility model has simple structure and realizes low backlash transmission, causing that the running of the motor is stable; the outputted torque of the motor can be increased. Because of a direct insertion type, the operation is simple. The utility model can be used matched with servomotors or step motors in any type.
Description
Technical field
The utility model relates to a kind of speed reducer, specifically, relates to a kind of low sideshake planet-gear speed reducer.
Background technique
Along with the industrial control automation degree is more and more higher, actuating motor and stepper motor frequently use in industry equipment; Matching used speed reducer is widely used in mechanical field.Planetary speed reducer has that speed ratio is big, output torque is big, volume is little, the efficient advantages of higher.But common planet-gear speed reducer has 3 pairs or 4 pairs to participate in engagement because of gear simultaneously, so the requirement on machining accuracy height; After adopting load balancing mechanism, complex structure, manufacture cost height.This class formation is " mechanical design handbook " of tool industry publishing house publication according to circumstances.
Planet-gear speed reducer (NGW type) with NBS adopts sun gear and planet carrier or the unsteady technology of ring gear, common way is to adopt tooth-like shaft joint or spline to be applied in sun gear and the planet carrier, and the bearing of sun gear and planet carrier is separately fixed on former and later two end caps, above mechanism reuses, reduced transmission efficiency, higher to the processing request of workpiece, be difficult to centering, volume is big, complex structure.
Existing speed reducer adopts the Placement of two ends shaft and splined hole usually, as shown in Figure 1, promptly adopts coupling 1 that the input shaft of speed reducer J and the output shaft of power source D (as motor or oil hydraulic motor) are connected.
In the modern industry transmission, more and more higher to the requirement of the position degree of transmission and precision, there is certain error in above Placement.
Summary of the invention
The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect that traditional speed reducer exists, and a kind of low sideshake planet-gear speed reducer is provided.This speed reducer is a kind of direct insertion planet-gear speed reducer of having simplified.
The purpose of this utility model is achieved in that
On the basis of existing speed reducer J, increased coupling 1, and the one-level sun wheel shaft 16 of coupling 1 and speed reducer J is integrated, its kind of drive is as shown in Figure 2.
Specifically, as shown in Figure 3, the utility model is made up of following parts, and its position and annexation are:
On the central axis of casing, from left to right, be followed successively by rear flange 17, coupling 1, one-level sun wheel shaft 16, one-level sun gear 3, middle planetary frame 6, secondary sun gear 15, output shaft 13, and interconnect successively;
At middle planetary frame 6 the right and lefts one-level planet wheel shaft 7 and secondary planet wheel shaft 11 are arranged respectively, one-level planet wheel 4 is arranged on one-level planet wheel shaft 7, secondary planet wheel 10 is arranged on secondary planet wheel shaft 11; One-level planet wheel 4 and 3 engagements of one-level sun gear, secondary planet wheel 10 and 15 engagements of secondary sun gear;
The utlity model has following advantage and good effect:
1. simplify the structure, reduced cost, saved the space, benefit is improved greatly;
2. driving error is little, has realized low sideshake transmission demand, and motor is operated steadily, and has improved the output torque of motor.
3. because be direct insertion, make simple to operate;
4. can with any type of actuating motor or the supporting use of stepper motor.
In a word, because therefore the utility model price performance height has a extensive future.
