Abstract
The utility model relates to a trapezoid lead screw, in particular to a trapezoid lead screw grease lubricating structure which comprises a trapezoid lead screw and a trapezoid screw nut. The trapezoid screw nut is connected to the trapezoid lead screw in a rotating mode. The trapezoid lead screw grease lubricating structure is characterized in that the cross section of the trapezoid screw nut is in a T shape, a lubricating oil nozzle is arranged on the right side wall of the trapezoid screw nut, an oil hole is formed in the upper end face of the trapezoid screw nut in the perpendicular downward direction, an outlet of the lubricating oil nozzle is connected with the oil hole, and a circle of oil storage groove is formed in the middle of the inner wall surface of the trapezoid screw nut and communicated with the oil hole. The trapezoid lead screw grease lubricating structure is simple in structure, good in lubricating effect and low in cost.
Description
Technical field
The utility model relates to a kind of trapezoidal screw, is specifically related to a kind of trapezoidal screw grease lubrication structure.
Background technique
Lubricated thin oil lubricant and the grease lubrication of being generally divided into of existing trapezoidal screw, some miniature leading screw adopts selflubricating resin to make feed screw nut.But various lubricated schemes all exist larger narrow limitation: thin oil lubricant is had relatively high expectations to the installation form of leading screw, vertical installation is difficult to adopt oil lubrication; The load that selflubricating leading screw can bear is limited, inapplicablely in medium and middle load environment, moves; Grease lubrication can be installed with arbitrary form, if but load is large and operation is frequent, just need constantly to add lubricating grease, if increase a set of automatic lubricator, can increase again the cost of whole machine.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, high lubricating effect, the trapezoidal screw grease lubrication structure that cost is low.
The purpose of this utility model is achieved through the following technical solutions: trapezoidal screw grease lubrication structure, comprise trapezoidal screw and trapezoidal screw nut, trapezoidal screw nut is rotatably connected on trapezoidal screw, it is characterized in that: the sectional shape of described trapezoidal screw nut is T-shaped, described trapezoidal screw nut right side wall top is provided with grease fitting, described trapezoidal screw nut upper-end surface has oilhole vertically downward, the outlet of described grease fitting is connected with described oilhole, internal face middle part one circle of described trapezoidal screw nut is provided with oil storage tank, described oil storage tank communicates with oilhole.
Described oilhole tapping is provided with plug.Prevent that grease from overflowing and preventing that other foreign material of dust from falling into.
Adopt technique scheme, the utility model trapezoidal screw grease lubrication structure has increased an oil storage tank on the basis of traditional feed screw nut, first lubricating grease is filled up when mounted to this oil storage tank, then pack trapezoidal screw into, trapezoidal screw can import grease screw thread surface of contact in the time of operation like this, and can grease not extruded to feed screw nut as traditional leading screw, this has improved secondary lubricated interval time to a great extent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model trapezoidal screw grease lubrication structure.
1 is trapezoidal screw, and 2 is plug, and 3 is trapezoidal screw nut, and 4 is grease fitting, and 5 is oilhole, and 6 is oil storage tank, and 7 is upper-end surface, and 8 is right side wall.
Embodiment
With reference to Fig. 1, trapezoidal screw grease lubrication structure, comprise trapezoidal screw 1 and trapezoidal screw nut 3, trapezoidal screw nut 3 is rotatably connected on trapezoidal screw 1, the sectional shape of described trapezoidal screw nut 3 is T-shaped, described trapezoidal screw nut 3 right side wall 8 tops are provided with grease fitting 4, described trapezoidal screw nut 3 upper-end surfaces 7 have oilhole 5 vertically downward, the outlet of described grease fitting 4 is connected with described oilhole 5, internal face middle part one circle of described trapezoidal screw nut 3 is provided with oil storage tank 6, and described oil storage tank 6 communicates with oilhole 5.
Described oilhole 5 tappings are provided with plug 2.Prevent that grease from overflowing and preventing that other foreign material of dust from falling into.
