Description
Technical Field
The utility model belongs to the field of engineering machinery, and particularly relates to a staggered arrangement structure of rotary motors.
Background
The excavator rotary motor is a direct driving element for the rotation operation of the excavator, the traditional excavator is driven by a single motor, the driving force requirement on the rotary motor is higher and higher along with the increase of the weight of the whole excavator, the cost of a large-size driving motor is very high, the motor starting and braking impact is large, and the requirement on the strength of a gear of a speed reducer is high.
The existing industry also widely adopts a structure of double-rotation motor arrangement, has obvious advantages compared with a single-rotation motor, has two main installation structures, one structure is a disc type flange fixing structure directly, and the other structure is a flange trimming fixing structure. As shown in fig. 3, the disc type flange fixing structure has large occupied space, large required frame width, limited pipeline arrangement space, narrow maintenance space and large maintenance difficulty; as shown in fig. 4, the flange trimming fixing structure requires machining a section of arc to the flange, resulting in poor motor versatility, increased cost, reduced mounting holes due to cutting, and reduced fixing strength.
At present, a novel rotary motor staggered arrangement structure which is compact in structure and capable of saving space is lacking, and original installation strength can be ensured.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
Embodiment 1, a rotary motor staggered arrangement structure, as shown in fig. 1, includes two flanges, one flange is provided with a rotary motor i 1, and the other flange is provided with a rotary motor ii 3; twelve mounting holes 2 are circumferentially distributed on the flange body, the twelve mounting holes 2 are uniformly distributed, the distances between the holes are equal, the flange is assembled on the frame 4 through the twelve mounting holes 2, two sides of the flange are provided with butt joint structures which are mutually staggered and meshed, the adjacent flanges define mounting positions through the butt joint structures, and the purpose of reducing mounting space can be achieved through the butt joint structures.
In the embodiment 2, a rotary motor staggered arrangement structure, the butt joint structure refers to three adjacent mounting holes 2 on two sides of a flange, concave grooves 7 are arranged at the interval positions of the three adjacent mounting holes 2, protrusions 8 are arranged at the outer side edge positions of the middle mounting holes 2 on the flange, the concave grooves 7 are connected with the radians of the protrusions 8, the sizes of the protrusions 8 and the concave grooves 7 are just mutually consistent and filled, and the whole butt joint structure is in a wavy shape; as shown in fig. 2, the concave 7 of the flange is matched with the convex 8 of the adjacent flange in a staggered and toothed manner, and is bolted and fixed on the frame 4 through the mounting holes 2, so that the number of bolts is not reduced, and the original mounting strength is ensured; the rotary motor I1 and the rotary motor II 3 are installed up and down, the oil port I5 of the rotary motor I1 and the oil port II 6 of the rotary motor II 3 face the same direction, and as shown in FIG. 2, the oil port I5 and the oil port II 6 are arranged in parallel, so that connection and arrangement of hydraulic pipelines are facilitated. The other steps are the same as in example 1.
In the prior art, a circular arc is needed to be cut on two sides of the flange, the machined flange can reduce the mounting holes 2, the fixing strength is reduced, and the single use is influenced; and the flange plate is not required to be processed for the second time, and the independent use of the rotary motor is not influenced.
