Abstract
The right angle bearing of hydraulic excavating power plants, relates to the support of large-scale mine hydraulic excavating power plants, and the present invention solves the problem that the quiet moment of flexure of hydraulic crawler excavator super high power motor transfinites.Described right angle bearing is made up of angle block of right angle, convex bent plate, stops and reinforcement gusset, the installed surface of convex bent plate has the supported hole connected with bell housing and is welded on the side, long limit of angle block of right angle according to the position of bell housing, the opposite side on the long limit of angle block of right angle is processed with installed surface and can opens according to the requirement of the quiet moment of flexure of motor the supported hole connected with gear-box on installed surface, the minor face of angle block of right angle has the supported hole connect with lower margin, strengthen gusset and be welded between the long limit of angle block of right angle and minor face.The present invention has that structure is simple, stability is strong, reliability is high, can realize the advantage that motor quiet moment of flexure size is adjustable.
Description
Technical field
The present invention relates to the support of large-scale mine hydraulic excavating power plants, particularly a kind of right angle bearing solving the quiet moment of flexure of hydraulic crawler excavator Diesel engine and transfinite.
Background technology
Usually, the support of the large-scale mine hydraulic excavating power plants be used as power with Diesel engine, as shown in Figure 1: its front-end and back-end connect with basis respectively by the lower margin hole of motor 01 and the lower margin hole of gear-box 02, engine rear end is then fixed on (in figure, 03 is bell housing and gear-box flange connect face) on gear-box by bell housing.For the power set of middle low power motor, this braced structures can meet the requirement of the quiet moment of flexure of motor.But for the power set of super high power Diesel engine, this braced structures then can cause the quiet moment of flexure of motor to transfinite.Even if utilize the screwed hole of bell housing side to increase support (as shown in Figure 2) by independent right angle bearing on bell housing, the quiet moment of flexure of motor still transfinites, and can not meet the demands.
Summary of the invention
Object of the present invention is intended to the shortcoming overcoming prior art, provides a kind of right angle bearing of hydraulic excavating power plants, solves the technical problem that the quiet moment of flexure of hydraulic crawler excavator super high power motor transfinites.
The present invention is achieved through the following technical solutions:
A kind of right angle bearing of hydraulic excavating power plants, its power set comprise: the motor containing flywheel, gear-box, it is characterized in that: described right angle bearing is by angle block of right angle, convex bent plate, stops and reinforcement gusset composition, the installed surface of described convex bent plate has the supported hole connected with bell housing, and the side, long limit of described angle block of right angle is welded on according to the position of bell housing, the opposite side on the long limit of described angle block of right angle is processed with installed surface, and can open according to the requirement of the quiet moment of flexure of motor the supported hole connected with gear-box on installed surface, the minor face of described angle block of right angle has the supported hole connect with lower margin, described reinforcement gusset is welded between the long limit of described angle block of right angle and minor face.
Described stops is arranged on the installed surface of described convex bent plate, for locating and eliminate the shearing force of attachment bolt.
The present invention compared with prior art, has the following advantages and beneficial effect:
1. the present invention only has angle block of right angle, convex bent plate, stops and reinforcement gusset 4 parts, all can be processed by rolled plate, and as a whole by welding assembly, and therefore, structure is simple, and stability is strong, and reliability is high.
2. the supported hole position due to the minor face of angle block of right angle connecting with lower margin, can move axially along motor according to the requirement of the quiet moment of flexure of motor, so it is adjustable to achieve motor quiet moment of flexure size, thus thoroughly solve the technical problem that the quiet moment of flexure of hydraulic crawler excavator super high power motor transfinites.

Fig. 1 is a kind of schematic diagram of braced structures (engine rear end bell housing does not support) of hydraulic excavating power plants prior art;
Fig. 2 is the schematic diagram of the braced structures (engine rear end bell housing supports) of another kind of hydraulic excavating power plants prior art;
Fig. 3 is the structural representation (axonometric drawing) of present pre-ferred embodiments.
Detailed description of the invention
Embody the exemplary embodiments of feature & benefits of the present invention, will describe in detail in the following description by reference to the accompanying drawings.Be understood that the present invention can have various changes in different embodiments, it neither departs from protection scope of the present invention, and explanation wherein and to be shown in be use when explain in essence, and be not used to limit the present invention.
As shown in Figure 3, a kind of right angle bearing of hydraulic excavating power plants, its power set comprise: the motor containing flywheel, gear-box, described right angle bearing is by angle block of right angle 1, convex bent plate 2, stops 3 and reinforcement gusset 4 form, the installed surface of described convex bent plate 2 has the supported hole 21 connected with bell housing, and the side, long limit 11 of described angle block of right angle 1 is welded on according to the position of bell housing, the opposite side on the long limit 11 of described angle block of right angle 1 is processed with installed surface, and can open according to the requirement of the quiet moment of flexure of motor the supported hole 111 connected with gear-box on installed surface, the minor face 12 of described angle block of right angle 1 has the supported hole 121 connect with lower margin, between the long limit 11 that described reinforcement gusset 4 is welded on described angle block of right angle 1 and minor face 12.
Described stops 3 is arranged on the installed surface of described convex bent plate 2, for locating and eliminate the shearing force of attachment bolt.
Structure of the present invention is mainly used in the not coplanar situation in bell housing side and gear-box side, if bell housing side and gear-box side coplanar, then can omit convex bent plate.
The long side of right angle bearing is for connecting bell housing and gear-box, and short brink supports for connecting lower margin, and the Working position of lower margin supported hole can move axially along motor, thus it is adjustable to realize motor quiet moment of flexure size, until be less than permissible value.
The present invention specifically can implement in a variety of forms and not depart from spirit or the essence of invention, so be to be understood that, above-described embodiment is not limited to aforesaid details, and should explain widely in claim limited range, therefore fall into change in claim or its equivalent scope and remodeling and all should be claim and contained.
