The utility model relates to a transmission device (1, 17), at least one gear (2, 18, 42) in the transmission device is positioned on a shaft neck (4, 20, 43), and the shaft neck (4, 20, 43) is supported on a housing (8, 24) of the transmission device (1, 17) by utilizing at least one support saddle (5, 21, 41).
Description
Technical field
The utility model relates to a kind of transmission device, wherein at least one pinion stand drop on the axle journal and described axle journal with at least one bearing support on the housing of transmission device.
Background technique
In DE 100 02 026 A1, such bearing has been described.This bearing is the bearing cage that is used to support the axle of intermediate gear under described situation.Described bearing often replaces the wall portion section in the housing of automotive transmission and is arranged on because manufacturing technology or mounting technology can't be constructed the place of wall portion section.In assembling this when device, axle journal inserts on a side in the corresponding hole of housing, subsequently the corresponding gear of suit and being assembled on opposite side in the corresponding accommodating part of bearing at last.This is equipped with a part of relative complex, this be because the space that is used to assemble each parts seldom.In addition, the central axis of axle journal must as far as possible accurately parallelly with the central axis of housing mesopore be aimed at one heart, thereby avoids gear to be used for undesirable oblique position and other form variations and the positional deviation of tooth position engaged.Yet in this case because the tolerance in the manufacturing of bearing itself and be fixed on bearing on the gear mechanism housing and the theoretic ideal position of journal centre's axis between the tolerance that causes of the manufacturing of distance, to the precision setting of described assembling boundary.
On the other hand, though owing to the space reason can be configured to bearing with the wall portion section of gear mechanism housing, the expense that is used for the cost of instrument in this case and is used for making subsequently bearing hole is than higher.In addition, the problem aspect the time also there is structure space in assembling in this case.At US 2,552, such bearing has been described among the 765A, be used to the ratchet that supports the transmission input shaft and can move thereon.
The model utility content
The purpose of this utility model is to propose a kind of device, and this device can simply and inexpensively be made, and can very accurately be assembled in the transmission device with small cost.
At least described bearing and axle journal are assembled into preassembled element of construction before in being assembled to transmission device.Design proposal of the present utility model proposes, and other is attached troops to a unit in supporting and be fixed on each parts on the bearing and is assembled into an element of construction before being assembled in the housing of automotive transmission with the supported in other words gear of the gear of bearing support and all.Because carry out the transmission device outside that is assemblied in of each parts more complicated, so when making each parts, can carry out this assembling inexpensively.For example can use on the one hand because assembly tool and other auxiliary implement that the cause of structure space can not directly be used in transmission device when each parts of assembling.Shorter and cost product is lower in the installation time at supplier and transmission device MANUFACTURER place on the other hand.The transmission device MANUFACTURER is alleviating burden aspect installation time and the cost, and this is because only structural group needn't need be assembled to each parts in the transmission device more now.This is, the transmission device MANUFACTURER is made a profit from this measure in this wise, has promptly saved structure complicated on the gear mechanism housing and has reduced the cost of making housing thus.
Bearing is the mechanical parts that the housing with transmission device separates on meaning of the present utility model, these mechanical parts have at least one or a plurality of accommodating part is used to support one or more axle journal, and are provided with the housing that one or more fixed block is used for bearing is fixed on transmission device.
Axle journal is interpreted as mechanical component on meaning of the present utility model, this mechanical component is rotating shaft, axle or pin, and is suitable for supporting one or more gear.Rotating shaft is particularly useful for rotatably mounted gear, rather than by the transmitted power of rotating shaft own.Axle is being that power transmits part aspect flowing.
Axle journal is short rotating shaft or axle, the planetary pinion pin in the planetary transmission for example, and it only is used to support the gear of described device, and therefore also just supported with respect to the housing of transmission device by bearing.
Can with gear rotatably radial support on axle journal.As its replacement scheme, each gear is connected with axle journal antitorquely, and this axle journal rotatably radial support in bearing.Function on described device is decided, and the combination of foregoing supporting role also is provided.In addition, described gear also can move with respect to bearing with axle journal or move with respect to axle journal on axle journal alternatively vertically together.In addition, unsteady bearing or rigid bearing are set.The compensatory earth's axis of bearing of floating is to working movingly.Rigid bearing does not allow compensating motion in the axial direction.
The housing of transmission device is interpreted as the structure and the structure member of all supporting structure classes, the mechanical component that holds thereon, supports or pack into, as being used to transmit the gear that can flow.Except typical housing, the planetary carrier of planetary transmission, differential motion and other transmission device housing is in other words also correspondingly calculated interior.
Accommodating part in the bearing for example is to be used to hold through hole or the blind hole that axle journal is used for sliding bearing or rolling bearing in other words, and axle journal utilizes this accommodating part to be bearing in the bearing.
Design proposal of the present utility model proposes, and bearing and axle journal can not interconnect dividually.Can not interconnect dividually and be meant that described parts can not without damage be separated from each other.Bearing and axle journal or structure all-in-one-piece, otherwise form fit connect ground, power transmission connect ground in other words material fit ground mutually inseparable turning up the soil be connected to each other.
An optional design proposal of the present utility model proposes, and bearing and axle journal can without damage be separated from each other.Without damage be meant, can described structure member be repeatedly interconnected by the Protean assembly method that can expect, and can be separated from each other again, and can not damage the structure and the function of described structure member.
Preferred design of the present utility model proposes, and bearing is the deformable member of being made by sheet metal.Especially can make inexpensively in extensive the manufacturing by the bearing that cold deformation for example stretches, casts, bending or punching press are made, and therefore than more cheap by foundry goods manufacturing shell section.Does not make with can having cutting the accommodating part of thread section on the bearing or slot shape yet, and bearing is fixed on the corresponding drive mechanism parts by means of thread section or accommodating part, and perhaps journal rest is in thread section or accommodating part.Screw thread for example passes through roll extrusion.The accommodating part is to be used to the molding of constructing the stripping pattern of through hole or being used to construct the peviform of blind hole.In addition, sliding bearing, pin, contact pin or other guiding element form fit connect ground in other words, power transmission connects ground or material is fixed on the bearing with connecting for fixed block such as nut or bolt, rolling bearing.
Be described in detail in other design proposal of the present utility model and the mode of execution chapters and sections " embodiment " below.
