Abstract
The utility model discloses an assembly structure for a planet carrier of a high speed and heavy load planetary speed reducer. The assembly structure comprises the planet carrier, a distance ring, bearings, planet wheels, a planet shaft, a steel ball and a bolt, wherein a planet axle hole is drilled on the planet carrier; the planet axle hole is a blind hole on which a semicircular groove is formed; the distance ring is located at one end close to the blind hole of the planet axle hole; one end of the planet shaft is fixed in an inner hole of the distance ring while the other end is installed in the planet axle hole through the steel ball; two bearings are installed outside the middle section of the planet shaft; the planet wheels are arranged outside the bearings. According to the assembly structure for the planet carrier of the high speed and heavy load planetary speed reducer disclosed by the utility model, the planet shaft is fixed by the bolt, therefore a relatively large axial load can be born; a gasket can be added on the end face of the planet shaft or the distance ring can be reorganized, so that axial clearances of the bearings can be well controlled; since inner rings of the bearings are matched with the planet shaft in a relatively loose manner, installment and correction of machining error are facilitated; the planet axle hole is the blind hole, so that oil leakage is prevented.
Description
Technical field
The utility model relates to a kind of driving mechanism, particularly a kind of planet carrier assembly structure of high-speed overload planetary speed reducer.
Background technique
Planet carrier assembling is most important transmission part in planetary speed reducer.In traditional planet carrier, planet axis hole is that through hole can not seal, the use that is not suitable for for planet carrier as decelerator shell.Traditional planet carrier assembles multiplex snap ring rigid bearing, radially using the fixed planet shafts such as pin, screw or axle end baffle plate, such fixation method is not too applicable to the planetary mechanism of high-speed overload, fragile, easily there is axial float or circumferentially rotate the bad control of axial clearance in planet axis.
Summary of the invention
The problems referred to above that exist for solving prior art, the utility model will design that a kind of structure is not fragile, planet axis is held and is difficult for that axial float occurs or circumferentially rotates and the planet carrier assembly structure of the controllable high-speed overload planetary speed reducer of axial clearance.
To achieve these goals, the technical solution of the utility model is as follows: a kind of high-speed overload planetary speed reducer planet carrier assembly structure.
To achieve these goals, the technical solution of the utility model is as follows: a kind of novel high speed heavy duty planetary speed reducer planet carrier assembly structure, comprise planet carrier, distance ring, bearing, planet wheel, planet axis, steel ball and bolt, on described planet carrier, be drilled with planet axis hole, described planet axis hole is blind hole, and have semi-circular groove, described distance ring is positioned at planet axis hole one end near blind hole, described planet axis one end is arranged in distance ring endoporus, the other end is arranged in planet axis hole by steel ball, the outside, stage casing of planet axis is provided with two bearings, bearing is provided with planet wheel outward.
The number of planet wheel described in the utility model is more than 3 or 3.
Compared with prior art, the utlity model has following beneficial effect:
1, because planet axis of the present utility model is fixing with bolt, so the thrust load that can bear is larger.
2, because the utility model can be at planet axial end shimming, or rest and reorganization distance ring, so the axial clearance of bearing can better be controlled.
3,, because the utility model bearing inner race and planet axis are compared with loose fit, be convenient to install and the finishing of machining error.
4, because planet axis hole of the present utility model is blind hole, can make planet carrier as decelerator shell use, can leakage of oil.
Accompanying drawing explanation
2, the total accompanying drawing of the utility model, wherein:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is schematic three dimensional views of the present utility model.
In figure: 1, planet carrier, 2, distance ring, 3, bearing, 4, planet wheel, 5, planet axis, 6, steel ball, 7, bolt.
Embodiment
Below in conjunction with accompanying drawing 1, the utility model is described further.As shown in Figure 1-2, a kind of novel high speed heavy duty planetary speed reducer planet carrier assembly structure, comprise planet carrier 1, distance ring 2, bearing 3, planet wheel 4, planet axis 5, steel ball 6 and bolt 7, on described planet carrier 1, be drilled with planet axis hole, described planet axis hole is blind hole, and have semi-circular groove, described distance ring 2 is positioned at planet axis hole one end near blind hole, described planet axis 5 one end are arranged in distance ring 2 endoporus, the other end is arranged in planet axis hole by steel ball 6, the outside, stage casing of planet axis 5 is provided with two bearings 3, the outer planet wheel 4 that is provided with of bearing 3.
The number of planet wheel 4 described in the utility model is more than 3 or 3.
Installation step of the present utility model is as follows: planet carrier 1 is agent structure, on it, be drilled with planet axis hole, planet axis hole is blind hole, first distance ring 2 is put into blind hole, pack bearing 3 into planet wheel 4, first pack steel ball 6 in planet axis 5 into, steel ball 6 is aimed at the semi-circular groove on planet axis hole, then planet axis 5 is penetrated successively in planet axis hole, bearing 3 endoporus and distance ring 2 endoporus, then with bolt 7, planet axis 5 is fixed on planet carrier 1.
