Embodiment
Fig. 1 shows the stereogram of bracket 100.For example, bracket 100 is a part for Linear actuator.Therefore, its His part be may be mounted on the mounting platform 133 of bracket 100, and the part is then able to by bracket 100 along guide rail 131 It is moved linearly by.
Bracket 100 includes spindle nut receiver 101, spindle nut 105, guiding slide 109 and mounting platform 133. Spindle nut 105 includes internal thread, and the internal thread corresponds to the external screw thread of mandrel rod 115.Spindle nut 105 and mandrel rod 115 screw thread can be ball screws or guiding screw thread.
Spindle nut receiver 101 is used for the screw-in of spindle nut 105, and is for example formed by metal-molding part. After the screw-in of spindle nut 105, the spindle nut is located at spindle nut receiver 101 in the way of non-rotatably connecting It is interior.Spindle nut receiver 101 is fastened to by screw 135 on guiding slide 109.Slide 109 is guided along the quilt of guide rail 131 Guiding.
Movement of the bracket 100 on linear direction is limited by guide rail 131 and guiding slide 109.If mandrel rod 115 Rotation, then non-rotatable spindle nut 105 is along the displacement of mandrel rod 115.By this way, whole bracket in a direction or It is moved linearly by another direction.
Spindle nut receiver 101 includes the first lubricant entry hole 103-1, and it is used to supply lubricant to lubricate guide rail Guiding slide 109 on 131.In addition, spindle nut receiver 101 includes another lubricant entry hole 103-2, and it is used for Lubricant is supplied to lubricate the spindle nut 105 in mandrel rod 115.For example, lubricant is oil or grease.However, general Other suitable lubricants can also be used.
Fig. 2 shows the viewgraph of cross-section of the front view in left side and the bracket 100 on right side.Spindle nut 105 is in axial side It is screwed into upwards in spindle nut receiver 101.Mandrel rod 115 is protruding at the middle part of spindle nut 105.Two lubrications Agent ingate 103-1 and 103-2 is located at the top of spindle nut 105.Lubricant entry hole 103-1 and 103-2 are arranged to and mandrel The diameter parallel of bar 115.Guiding slide 109 is joined in the profile of guide rail 131.
Spindle nut receiver 101 includes surrounding circumferential milling (milled) region of the opening for spindle nut 105, The region forms lubricant passageway 111 together with the outside of spindle nut 105, and the lubricant passageway laterally bypasses the mandrel of screw-in Nut 105.Lubricant entry hole 103-1 enters in lubricant passageway 111.Lubricant outlet hole 107 is located at spindle nut 105 With lubricant entry hole 103-1 substantially relative sides.Lubricant outlet hole 107 flows out lubricant, (flat in figure backward In face) reach on guiding slide 109.By the lubricant outlet hole 107, lubricant is supplied to from lubricant passageway 111 and drawn Guide sliding base 109.Lubricant entry hole 103-1 and 103-2 arrangement allow that the portion that is arranged on mounting platform need not be being removed In the case of part, lubricant is supplied at the easily accessible point of spindle nut receiver 101.
Lubricant passageway 111 connects lubricant entry hole 103-1 and lubricant outlet hole 107 in the way of C-shaped.Lubrication Agent passage 111 includes storeroom 113, and lubricant may collect in the inner side of spindle nut receiver in the storeroom.Pass through Lubricant passageway 111 is widened to form storeroom 113.In this way it is possible to collect lubricant, thus its can be used for it is longer Lubricate to phase guiding slide 109.
Fig. 3 shows two side cross-sectional views of bracket 100.Lubricant entry hole 103-1 enters in spindle nut Lubricant passageway 111 on the inner side of receiver 101.Spindle nut 105 includes circumferential recess 123, and lip ring 125 is inserted Into the circumferential recess 123 to prevent lubricant from being leaked from lubricant passageway 111.
In addition, spindle nut receiver 101 includes another lubricant passageway 119, by another lubricant passageway in core Spindle nut 105 is lubricated on axostylus axostyle 115.Lubricant is supplied to by mandrel rod 115 by radial direction lubricant outlet hole 121.
In the downside of spindle nut receiver 101, lubricant enters from lubricant passageway 107 via lubricant outlet hole 107 Enter to guide in slide 109.Tie point between lubricant outlet hole 107 and guiding slide 109 is sealed by sealing ring 137.Pass through Lubricant is incorporated on the guide rail 131 of the inner side of guiding slide 109 by other lubricant passageway (not shown).
Spindle nut 105 includes external screw thread in outside, and this screws into corresponding interior in spindle nut receiver 101 Screw thread 129.
Fig. 4 shows the viewgraph of cross-section of another front view of the bracket 100 in left side and the bracket 100 of centre, and right The side view of the spindle nut 105 of side.The cross section be located at another point different from the point shown in Fig. 2, and with lubrication Agent passage 119 intersects, and is that the lubricant passageway 119 supplies lubricant by lubricant entry hole 103-2.Lubricant passageway 119 Produced by complete circumferential depression 117, it is recessed between two parts of different-diameter to produce the circumference in spindle nut 105 Fall into.
By the circular lubricant passageway 119 produced by complete circumferential depression 117, no matter which spindle nut 105 is in Individual rotation position, can supply lubricant by lubricant entry hole 103-2.Thus, lubrication in position with spindle nut 105 position is unrelated.
Lubricant is introduced in the lubricant outlet hole 121 radially extended of spindle nut 105 from lubricant passageway 119, Mandrel rod 115 is reached, and for lubricating spindle nut 105 at the position.Spindle nut 105 includes external screw thread 127, to revolve Enter the internal thread 129 in spindle nut receiver 101.
Fig. 5 shows another side cross-sectional view of the bracket 105 at lubricant entry hole 103-2 position.Lubrication Agent ingate 103-2 is formed by two vertical channels.Lubricant entry hole 103-2 access road 139 prolongs in the axial direction Stretch.Adjoin passage 141 perpendicular to access road 139, and closed by unshowned ball sealing in side.
Fig. 6 is the block diagram for lubricating the method for the guiding slide 109 of Linear actuator.The method comprising the steps of 101： Lubricant is supplied to the lubricant entry hole 103-1 of spindle nut receiver 101 on the side of spindle nut 105.In addition, should Method includes step S102：Lubricant is set to bypass spindle nut 105 by lubricant passageway 111；And step S103：Pass through core Lubricant is discharged to the guiding slide on the opposite side of spindle nut 105 by the lubricant outlet hole 107 of axle nut receiver 101 On 109.
In addition, lubricant is supplied in mandrel rod 115 by another lubricant passageway 119, another lubricant passageway Formed by the circumferential depression 117 in spindle nut 105.In by this way, the lubrication design for bracket 100 is realized, should Bracket may include the ball screw of recycling and the ball guide of recycling.The rear lubrication of the part slided on top of each other can be with Carried out easily via lubricant entry hole 103-1 and 103-2 at any time.
Lubricant passageway 111 and 119 is arranged on the inner side of spindle nut receiver 101, and is closed in spindle nut 102 When produce.
All features for combining to explain and show from each embodiment of the present invention can be provided with different combinations According in subject of the present invention, so as to realize its advantage simultaneously.
All method and steps can be implemented by the equipment for being adapted for carrying out each method and step.By forming present subject matter Function performed by the feature of a part can be the method and step of method.
Protection scope of the present invention is defined by the claims, and is not limited to spy being explained in explanation or being shown in accompanying drawing Levy.
