Abstract
The invention relates to a bolt, in particular to a bolt for fixing a drive motor of a road roller. The bolt comprises a screw cap and a screw, wherein a first cylinder, a second cylinder and a third cylinder are arranged at one end, contacted with the screw cap, of the screw in sequence; the diameters of the first cylinder, the second cylinder and the third cylinder are in the ratio of 1:2:1, and the heights of the first cylinder, the second cylinder and the third cylinder are in the ratio of 6:1:7; screw threads are formed in the outer surface of the third cylinder. By the adoption of a special structure, the bolt for fixing the drive motor of the road roller has a good positioning effect and is long enough to fix the drive motor, so that the motor is fixed firmly, and the motor is prevented from falling during a transporting process.
Description
Technical field
The present invention relates to a kind of bolt, relate in particular to a kind of for the fixing bolt of road roller drive motor.
Background technique
Road roller, with Action of Gravity Field of machinery itself, is applicable to various compacting operations, makes to be produced permanent deformation by rolling layers and closely knit.Road roller belongs to the category of road equipment in engineering machinery, the embankment compacting operation that is widely used in the Larger Engineering Projects such as high-grade highway, railway, airfield runway, dam, stadium, can roll sand, half viscosity and clay soil, subgrade stability soil and asphalt concrete pavement layer.
In assembling, during road roller, the drive motor of vibrating wheels need be arranged on vibration damper, and motor is with wheel holding, volume is large, quality is large, so need to adopt suspender that motor is transported to mounting point.Prior art is the fixing comparatively trouble on suspender for motor, and general suspender all adopts plain bolt to be fixed motor, at motor, transports in process, and bolt is easily loosening, thereby causes that motor mounting points is loosening, causes motor in the process of transporting, to drop, damage.
Summary of the invention
the problem that 1, will solve
For motor in road roller, be arranged on vibration damper, and motor general plain bolt that adopts on suspender, motor transports in process, and bolt is easily loosening, thereby causes that motor mounting points is loosening, the problem that causes motor to transport in process to drop, damage, the invention provides that a kind of it adopts special structure for the fixing bolt of road roller drive motor, it has good positioning action, can make motor fixed, prevent that motor from dropping in the process of transporting.
2, technological scheme
For addressing the above problem, the present invention adopts following technological scheme.
For a fixing bolt for road roller drive motor, comprise nut, screw rod, described screw rod starts to be followed successively by the first cylindrical body, the second cylindrical body and three cylindrical body from the one end that contacts nut; The diameter ratio of described the first cylindrical body, the second cylindrical body and three cylindrical body is 1:2:1, and the ratio of height is 6:1:7; Described three cylindrical external surface is provided with screw thread.
Preferably, on described nut 1, have groove, described groove shapes is long strip.
Preferably, the material of described bolt is No. 45 steel.
Wherein, the fixing and long strip of groove shapes, can be also quincunx or other polygonals, is mainly that bolt is facilitated is stressed, bolt can be installed fastening.
3, beneficial effect
Than prior art, beneficial effect of the present invention is:
(1) screw portion of the present invention is followed successively by the first cylindrical body, the second cylindrical body and three cylindrical body; The diameter ratio of described the first cylindrical body, the second cylindrical body and three cylindrical body is 1:2:1, and the ratio of height is 6:1:7; And three cylindrical external surface is provided with screw thread, adopt the screw rod of this spline structure, can be to clamping bolt the length in fitting seat carry out spacingly, make bolt have sufficient length to realize drive motor fixed, make motor fixing more stable on suspender, prevent that motor from dropping in the process of transporting.
(2) material of the present invention is No. 45 steel, and the more general steel of its intensity is higher, thereby bolt is higher working life.
(3) the present invention is simple in structure, easy to operate, is easy to manufacture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is plan view of the present invention.
Number in the figure explanation: 1, nut; 2, the first cylindrical body; 3, the second cylindrical body 4, three cylindrical body; 5, groove.
Embodiment
For further understanding content of the present invention, below in conjunction with Figure of description and specific embodiment, describe the present invention.
embodiment 1
For a fixing bolt for road roller drive motor, comprise nut 1, screw rod, it is characterized in that, described screw rod starts to be followed successively by the first cylindrical body 2, the second cylindrical body 3 and three cylindrical body 4 from the one end that contacts nut 1; The diameter ratio of described the first cylindrical body 2, the second cylindrical body 3 and three cylindrical body 4 is 1:2:1, and the ratio of height is 6:1:7; Described three cylindrical body 4 outer surfaces are provided with screw thread, adopt the screw rod of this spline structure, can be to clamping bolt the length in fitting seat carry out spacingly, make bolt have sufficient length to realize drive motor fixed, make motor fixing more stable on suspender, prevent that motor from dropping in the process of transporting.
As a kind of optimal way, on nut 1, have groove 5, described groove 5 is shaped as long strip.
As another optimal way, No. 45 steel of the material selection of bolt, No. 45 the more general steel of hardness of steel is higher, thus bolt is higher working life.
Use when of the present invention, to be hung drive motor is fixed on suspender by the present invention, because screw rod intermediate portion larger diameter part of the present invention can be carried out spacing by the length of installation in suspender to the present invention, thereby making bolt have sufficient length to realize fixes drive motor, make motor fixing more stable on suspender, then drive motor is sling, move to before vibrating wheels vibration damper, rotation motor is aimed at the eyelet of vibration damper, loads onto plain bolt and tightens.
Claims (3)
1. for a fixing bolt for road roller drive motor, comprise nut (1), screw rod, it is characterized in that, described screw rod starts to be followed successively by the first cylindrical body (2), the second cylindrical body (3) and three cylindrical body (4) from the one end that contacts nut (1); The diameter ratio of described the first cylindrical body (2), the second cylindrical body (3) and three cylindrical body (4) is 1:2:1, and the ratio of height is 6:1:7; Described three cylindrical body (4) outer surface is provided with screw thread.
