Power dividing type planetary reducer planet wheel bearing method for maintaining
technical field:
The present invention relates to a kind of planet wheel bearing method for maintaining, especially power dividing type planetary reducer planet wheel bearing method for maintaining.
background technology:
Compared with fixed shaft type gear drive, the most outstanding advantage of planetary gearing is that volume is little, lightweight.Due to above-mentioned advantage, planetary transmission obtains to be applied more and more widely.Power dividing type planetary reducer is two-stage closed planetary gear device, its main feature is that transmitted power is large, power density is high, be mainly used in transmission main gear down device after boats and ships active force, it is one of power dividing type planetary reducer typical fault that planet wheel bearing damages, need its maintenance that changes the outfit, thinking traditionally, mainly contain following two kinds of method for maintaining: 1. on reducer shell, open bearing service hatch, so that the maintenance that changes the outfit of planet wheel bearing, and on housing, open the design difficulty that service hatch not only increases housing, and often because the characteristics of compact layout after boats and ships between drive apparatus causes being difficult to successfully complete changing the outfit of planet wheel bearing from service hatch, 2. decelerator upper shell is removed, expose driving member part, frock is utilized driving member part to be lifted, integral-rotation driving member, by " being embedded in " lower house, the planet wheel bearing that is not easy to dismounting rotates to easy-to-mount top, thus realizes changing the outfit of planet wheel bearing, its shortcoming when being maintenance needs decelerator to remove out from axle system, and need to design a large amount of frock and realize lifting and integral-rotation to its driving member part, maintenance load is large, and the cycle is long.
summary of the invention:
The invention provides a kind of power dividing type planetary reducer planet wheel bearing method for maintaining.Utilize the method can under the condition only dismantling decelerator upper shell, utilize planet wheel bearing frock to complete changing the outfit of planet wheel bearing, maintenance load be little, and the cycle is short.
Technical scheme of the present invention is: power dividing type planetary reducer planet wheel bearing method for maintaining, the method of the invention is applicable to the maintenance of power dividing type planetary reducer planet wheel bearing, is divided into the maintenance of differential stage planet wheel bearing to keep in repair two parts with enclosure class planet wheel bearing herein and is described;
Differential stage planet wheel bearing keeps in repair: dismounting upper shell, is exposed by the differential stage planet wheel bearing being placed in upper case portion, utilizes frock to change the outfit to differential stage planet wheel bearing; Rotating input shaft, carries out jiggering to planetary reducer, rotates the differential stage planet wheel bearing being placed in lower housing section to upper case portion, utilizes frock to change the outfit to differential stage planet wheel bearing; Continue jiggering, change the outfit until all differential stage planet wheel bearings all complete.
Enclosure class planet wheel bearing keeps in repair: dismounting upper shell, is exposed by the enclosure class planet wheel bearing being placed in upper case portion, utilizes frock to change the outfit to enclosure class planet wheel bearing; Output shaft restraint device is utilized to fix output shaft, and remove enclosure class planet carrier restraint device, now driving type becomes inversion type tandem type Planetary Gear Transmission from power dividing type Planetary Gear Transmission, by jiggering power shaft, the enclosure class planet wheel bearing being placed in lower housing section can be rotated to upper case portion, utilize frock to change the outfit to enclosure class planet wheel bearing; Continue jiggering, change the outfit until all enclosure class planet wheel bearings all complete, after having changed the outfit, remove output shaft restraint device, and recover enclosure class planet carrier restraint device is installed.
The present invention has following beneficial effect: keep in repair, change the outfit planet wheel bearing time, without the need to planetary reduction gear is taken apart from axle system, under the condition of connection axle series, by jiggering by planet wheel bearing from be not easy to keep in repair position rotate to be convenient to keep in repair position.Maintenance load is little, and the cycle is short.

detailed description of the invention:
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, power dividing type planetary reducer planet wheel bearing method for maintaining, the method of the invention is applicable to the maintenance of power dividing type planetary reducer planet wheel bearing, is divided into the maintenance of differential stage planet wheel bearing to keep in repair two parts with enclosure class planet wheel bearing herein and is described.
Differential stage planet wheel bearing keeps in repair: dismounting upper shell 1, is exposed by the differential stage planet wheel bearing 3 being placed in upper shell 1 part, utilizes frock to change the outfit to differential stage planet wheel bearing 3; Rotating input shaft 6, carries out jiggering to planetary reducer, rotates the differential stage planet wheel bearing 3 being placed in lower house 2 part to upper shell 1 part, utilizes frock to change the outfit to differential stage planet wheel bearing 3; Continue jiggering, change the outfit until all differential stage planet wheel bearings 3 all complete.
Enclosure class planet wheel bearing keeps in repair: dismounting upper shell 1, is exposed by the enclosure class planet wheel bearing 4 being placed in upper shell 1 part, utilizes frock to change the outfit to enclosure class planet wheel bearing 4; Output shaft restraint device 8 is utilized to fix output shaft 7, and remove enclosure class planet carrier restraint device 5, now driving type becomes inversion type tandem type Planetary Gear Transmission from power dividing type Planetary Gear Transmission, by jiggering power shaft 6, the enclosure class planet wheel bearing 4 being placed in lower house 2 part can be rotated to upper shell 1 part, utilize frock to change the outfit to enclosure class planet wheel bearing 4; Continue jiggering, change the outfit until all enclosure class planet wheel bearings 4 all complete, after having changed the outfit, remove output shaft restraint device 8, and recover enclosure class planet carrier restraint device 5 is installed.
Utilize and simply retrain frock, become possess revolution characteristic by originally not possessing revolution characteristic Planetary Gear Transmission, again by jiggering planetary reducer, to lower housing section be placed in, and be not easy to the planet wheel bearing of dismounting and rotate to easy-to-mount upper case portion, thus realize the changing the outfit of planet wheel bearing, maintenance work.
