In order to achieve the above object, the utility model provides a bolt assembly who is fit for motor installation, include the bolt, eccentric gasket and the nut of constituteing by screw rod and nut, the screw rod includes first screw rod and second screw rod at least, the nut set up in the first end of first screw rod, the first end of second screw rod with the second end of first screw rod links to each other, the second screw rod is formed with the screw thread, first screw rod with the nut is concentric, the second screw rod for first screw rod and nut eccentric settings, be formed with eccentric gasket hole on the eccentric gasket, the center in eccentric gasket hole for the center of eccentric gasket is eccentric distribution, eccentric gasket hole with second screw rod phase-match, the nut with second screw rod phase-match.
Further, the outer diameter of the eccentric gasket is larger than the aperture of the equipment base hole, and the eccentric gasket is located between the upper surface of the equipment base hole and the nut.
Further, the eccentric gasket is also arranged between the lower surface of the equipment base hole and the upper surface of the base hole.
Further, the thread is in a coarse thread self-locking form or a fine thread form.
The above technical scheme of the utility model has following beneficial effect:
the bolt assembly provided by the utility model can smoothly fasten the motor and the base without reaming operation when the motor base hole and the base hole are not concentric after the motor and the base are aligned and centered, thereby improving the fastening efficiency and reliability of the bolt in the eccentric hole, saving the installation cost of equipment and reducing the operation risk;
other advantageous effects of the present invention will be described in detail in the following detailed description.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The various specific features and embodiments described in the detailed description may be combined in any suitable manner, for example, different embodiments may be formed by combining different specific features/embodiments, and in order to avoid unnecessary repetition, various combinations of the specific features/embodiments of the present invention are not described separately.
It should be noted that the terms "disposed" and "connected" should be interpreted broadly, and may be, for example, directly disposed, installed, connected, or indirectly disposed and connected through intervening components and intervening structures. In addition, the directions or positional relationships indicated in the present invention, such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on the directions or positional relationships shown in the drawings or the conventional placing states or using states, and are only for convenience of description and simplification of description, but do not indicate or imply that the structure, feature, device or element referred to must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.
As shown in fig. 1, an embodiment of the present invention provides a bolt assembly suitable for motor installation, which includes a bolt composed of a screw and a nut 1, an eccentric washer 4, and a nut 5. The screw rod includes first screw rod 2 and second screw rod 3, and nut 1 sets up in the first end of first screw rod 2, and the first end of second screw rod 3 links to each other with the second end of first screw rod 2, and second screw rod 3 is formed with the screw thread, and nut 1, first screw rod 2 and second screw rod 3 structure as an organic whole. The first screw 2 and the nut 1 are concentrically arranged, and the second screw 3 is eccentrically arranged relative to the first screw 2 and the nut 1. The eccentric shim 4 is formed with an eccentric shim hole 6, and the center of the eccentric shim hole 6 is eccentrically distributed with respect to the center of the eccentric shim 4 and is equal to the eccentricity value of the second screw 3 with respect to the first screw 2. Wherein, eccentric gasket hole 6 is supporting with second screw rod 3, and nut 5 and second screw rod 3 phase-match, and the external diameter of eccentric gasket 4 is greater than the external diameter of first screw rod 2 and the aperture of equipment base hole (base hole is generally the same with equipment base hole aperture).
When motor and base installation, pass the second screw rod 3 and the first screw rod 2 of bolt from the back (lower surface) in base hole, make the back laminating in nut 1 and base hole, first screw rod 2 alternates in the base hole, second screw rod 3 passes from the endocentric base hole of dead center and the common clearance in equipment base hole, the interlude is downthehole at the equipment base, rely on eccentric gasket hole 6 to embolia second screw rod 3 with eccentric gasket 4, reuse nut 5 twists into second screw rod 3, tighten nut 5 and accomplish the fastening of motor and base promptly.
