Abstract
The utility model discloses a heavy middle flange of integrated bearing inner race mainly includes middle support, middle flange, lock nut, middle integral key shaft, middle support bearing, the integration has middle support bearing on the excircle of middle flange, and middle support bearing installs on middle support, makes middle support and middle flange assemble into an assembly, and the middle flange of integrated middle support is installed on middle integral key shaft, and the integral key shaft realizes fixing a position in the middle of lock nut locking. The utility model discloses with the middle support integrated to in the middle of the bead to with bearing inner race with middle bead excircle surface machining lane replace, can effectively reduce part quantity, reduce the accumulative error after the assembly, the transmission shaft reduces to only needing to adorn two parts and can accomplish the assembly by three part, improves the assembly efficiency of transmission shaft assembly, reduces middle spline shaft length, reduces transmission shaft assembly weight, reduces transmission shaft inertia, improves the transmission shaft performance, the reduction oil consumption that starts.
Description
Technical Field
The utility model relates to a field of car transmission shaft, concretely relates to bead in middle of integrated bearing inner race's heavy.
Background
The existing transmission shaft assembly assembling structure is as follows: the middle bracket is internally provided with a bearing with an inner ring and an outer ring of the bearing, the bearing with the bracket is arranged on the middle spline shaft together, the middle flange is used for pressing the bearing onto the middle spline shaft, and the locking nut is used for locking to realize the positioning of the bearing.
Such a structure has the following drawbacks: the length of the middle spline shaft is too long, and the consumed material is large; the transmission shaft assembly is heavy; the rotational inertia of the transmission shaft assembly is large; the precision requirement of each part is high, and the accumulated error is large after assembly; the transmission shaft assembly has multiple assembly links and long assembly time.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a bead in middle of integrated bearing inner race's heavy.
The purpose of the utility model is accomplished through following technical scheme: the heavy middle flange of the integrated bearing inner ring mainly comprises a middle bracket, a middle flange, a locking nut, a middle spline shaft and a middle bracket bearing, wherein the middle bracket bearing is integrated on the excircle of the middle flange, the middle bracket bearing is arranged on the middle bracket, the middle bracket and the middle flange are assembled into an assembly, the middle flange of the integrated middle bracket is arranged on the middle spline shaft, and the locking nut locks the middle spline shaft to realize positioning.
Furthermore, a ball path used as a bearing inner ring is arranged on the excircle of the middle flange.
The utility model has the advantages that:
1. a ball channel is directly processed on the excircle of the middle flange to be used as a bearing inner ring, so that the number of parts is reduced, and the structure is simplified;
2. the middle spline shaft is not provided with a bearing, so that the length of the middle spline shaft is shortened, and the material consumption is reduced;
3. the rotational inertia of the transmission shaft assembly is reduced, and the oil consumption during starting is reduced;
4. the number of assembly parts is reduced, so that the accumulated error after assembly is reduced;
5. when the transmission shaft is assembled, three parts are originally required to be assembled, and only two parts are required to be assembled after the three parts are changed, so that the assembly efficiency of the transmission shaft assembly is improved.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: the middle bracket comprises a middle bracket 1, a middle flange 2, a locking nut 3, a middle spline shaft 4 and a middle bracket bearing 5.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached drawings, the heavy middle flange integrated with the bearing inner ring mainly comprises a middle bracket 1, a middle flange 2, a locking nut 3, a middle spline shaft 4 and a middle bracket bearing 5, wherein the middle bracket bearing 5 is integrated on the excircle of the middle flange 2, and the middle bracket bearing 5 is arranged on the middle bracket 1, so that the middle bracket 1 and the middle flange 2 are assembled into an assembly, the number of assembled parts is reduced, the accumulated error after assembly is reduced, and meanwhile, three parts originally required to be assembled in the assembly of a transmission shaft can be assembled only by assembling two parts, and the assembly efficiency of the transmission shaft assembly is improved; the middle flange 2 of the integrated middle bracket 1 is arranged on the middle spline shaft 4, the middle spline shaft 4 can cancel a bearing stop at a bearing installation part, the high-precision requirement of the middle spline shaft 4 for processing the bearing stop is reduced, and the length of the middle spline shaft 4 can be shortened; the locking nut 3 locks the middle spline shaft 4 to realize positioning.
The outer circle of the middle flange 2 is provided with a ball path used as a bearing inner ring, so that the design purpose of reducing one bearing inner ring can be achieved.
The utility model discloses with the middle support integrated to in the middle of on the bead to replace bearing inner race with middle bead excircle surface machining lane, can reduce part quantity, reduce middle spline shaft length, save middle spline shaft material, reduce transmission shaft assembly weight, reduce transmission shaft inertia, improve transmission shaft performance, reduce the oil consumption when starting. Meanwhile, the number of assembling parts is reduced, so that accumulated errors after assembling are reduced, three parts originally required to be assembled in the transmission shaft assembly can be assembled only by assembling two parts, and the assembling efficiency of the transmission shaft assembly is improved. The utility model discloses practical application in heavy transmission shaft assembly product has been.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
