Abstract

The utility model relates to a high-load output structure of a speed reducer, which comprises a speed reducer housing, an output shaft of the speed reducer, and a first bearing arranged between the speed reducer housing and the output shaft of the speed reducer; and the high-load output structure of the speed reducer is characterized in that a bearing seat is fixed on the speed reducer housing, and a second bearing is arranged in the bearing seat and connected with the output shaft of the speed reducer. The high-load output structure of the speed reducer has the advantages of simple structure, low cost and high bearing capacity.

Description

Speed reducer high-mechanic export structure

Technical field

The utility model relates to a kind of speed reducer high-mechanic export structure.

Background technique

The design of traditional speed reducer mainly is to consider to bear output torque, output shaft only can bear little radial force and axial force, when output shaft has bigger radial force and axial force, the speed reducer life-span can sharply descend, for guaranteeing the working life of speed reducer, present speed reducer carrying export structure normally is provided with clutch shaft bearing 2 ' between speed reducer 1 ' and speed reducer output shaft 3 ', speed reducer 1 ' the outer bearing support 5 ' that second bearing is arranged in that installs additional, speed reducer output shaft 3 ' is connected with second output shaft 6 ' by coupling 4 ', formation can be set up in the major axis (as shown in Figure 1) between speed reducer casing 1 ' and the bearing support 5 ', utilize bearing support A bearing load radial force and axial force, speed reducer only provides moment of torsion.Its major defect of this design is that whole speed reducer output mechanism length L 1 is obviously very long, and therefore the occasion that is restricted at some installing space just can't be used, simultaneously owing to the product structure complexity, and the cost height; Market competition does not have advantage.

Summary of the invention

For overcoming the above-mentioned shortcoming of prior art, it is a kind of simple in structure, with low cost that the utility model provides, the speed reducer high-mechanic export structure that bearing capacity is high.

Speed reducer high-mechanic export structure, comprise the speed reducer casing, speed reducer output shaft, and be arranged at clutch shaft bearing between speed reducer casing and the speed reducer output shaft, it is characterized in that: fixing bearing seat on the described speed reducer casing, be provided with second bearing in the described bearing support, described second bearing is connected with described speed reducer output shaft.

Further, the end away from described speed reducer casing of described bearing support is provided with end cap, and described end cap is affixed by screw and described bearing support.

Further, described bearing support is affixed by screw and described speed reducer casing.

Technical conceive of the present utility model is: a bearing support directly is installed on the speed reducer casing, is arranged second bearing of an energy bearing radial force or axial force in the bearing support; The specification size of the clutch shaft bearing and second bearing, form depend on that the output shaft of speed reducer just can bear big axial force and radial force like this by the size of suffered axial force of output shaft and radial force, thereby have expanded the application area of speed reducer.

Suffered axial force and radial force on the speed reducer output shaft acts on the bearing support by second bearing, affacts on the speed reducer casing by the screw that is distributed on the bearing support, thereby guarantees that axial force and radial force are unloaded on the firm speed reducer casing.

Advantage of the present utility model is:

1, the lubricating system of second bearing is a grease lubrication in the bearing support shown in Figure 1, bearing support shown in Figure 2 is because be to link together with the speed reducer casing, so can with the shared bath lubrication of speed reducer system, clearly this will improve the working environment of bearing support middle (center) bearing greatly.

2, reduce the installation volume of speed reducer output mechanism, thereby expanded the application area of speed reducer.

3, simplify driving mechanism, thereby the cost of whole speed reducer export structure is greatly reduced.

Description of drawings

Fig. 1 is the schematic representation of existing speed reducer export structure.

Fig. 2 is a schematic representation of the present utility model.

Embodiment

With reference to Fig. 2, further specify the utility model:

Speed reducer high-mechanic export structure, comprise speed reducer casing 1, speed reducer output shaft 2, and be arranged at clutch shaft bearing 3 between speed reducer casing 1 and the speed reducer output shaft 2, fixing bearing seat 6 on the described speed reducer casing 1, be provided with second bearing 5 in the described bearing support 6, described second bearing 5 is connected with described speed reducer output shaft 2.

End away from described speed reducer casing 1 of described bearing support 6 is provided with end cap 7, and described end cap 7 is affixed by screw and described bearing support 6.

Described bearing support 6 is affixed by screw 4 and described speed reducer casing 1.

The described content of this specification embodiment only is enumerating the way of realization of model utility design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
