Description
Technical field
The utility model relates to a kind of ball screw, belongs to mechanical spare part technical field.
Background technique
Ball screw is that a kind of nut and screw rod of utilizing relatively moves and the mechanical parts of transmission, and it has preferable machinery driving efficiency and is widely used.But,, may cause the friction between nut and screw rod to strengthen and the abrasion of acceleration ball screw if the long-time shortage of ball screw is lubricated.
Therefore, for avoiding above-mentioned technical problem, necessaryly provide a kind of structure improved ball screw, to overcome described defective of the prior art.
The model utility content
For addressing the above problem, the purpose of this utility model is to provide a kind of energy to continue from the ball screw that moistens.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of ball screw, and it comprises screw rod, nut, Fuel Tanking Unit, connector, wherein, described spiro cap is located on the screw rod and nut and screw rod can relatively move; Described Fuel Tanking Unit comprises an oil outlet and can store the oil storage space of lubricant oil that described oil outlet is communicated with oil storage space; Described connector is provided with oil through, be provided with joint in oil through one end, and the other end is provided with an engagement portion, and described joint is connected with nut, and the engagement portion is connected with oil outlet.
Ball screw of the present utility model also can be set to: described engagement portion is a projective structure, and oil outlet is groove structure.
Compared with prior art, the utlity model has following beneficial effect: ball screw of the present utility model is by being provided with a Fuel Tanking Unit, thereby realizes lubricating function.And the simple and installation of ball screw dismounting of the present utility model.
Description of drawings
Fig. 1 is the structural representation of ball screw of the present utility model.
Fig. 2 is the sectional view that the Fuel Tanking Unit of ball screw of the present utility model is connected with connector.
Embodiment
See also shown in Fig. 1,2, the utility model is a kind of ball screw, and it comprises screw rod 10, nut 20, Fuel Tanking Unit 30, connector 40.Wherein, described nut 10 is set on the screw rod 20 and nut 20 can relatively move with screw rod 10.Described Fuel Tanking Unit 30 comprises an oil outlet 32 and can store the oil storage space 33 of lubricant oil.Described fuel-displaced 32 are communicated with oil storage space 33.Described connector 40 is provided with oil through 42, be provided with joint 41 in oil through 42 1 ends, and the other end is provided with an engagement portion 44, and described joint 41 is connected with nut 20, and engagement portion 44 is connected with oil outlet 32.Described engagement portion 44 is a projective structure, and oil outlet 32 is groove structure, thereby engagement portion 44 and fuel-displaced 32 can closely be cooperated.
Ball screw of the present utility model is by being provided with a Fuel Tanking Unit 30, thereby realizes lubricating function.And the simple and installation of ball screw dismounting of the present utility model.
Above embodiment only is the preferred embodiment of this creation, not in order to limiting this creation, all in this creation spirit and principle within made any modification, be equal to replacement, improvement etc., all should be included within the protection domain of this creation.
