Description

The fixed type roller guide shoe

Technical field

The invention belongs to elevator spare parts manufacture technical field, be specifically related to a kind of fixed type roller guide shoe that is used for cage guide.

Background technology

For a long time, elevator is monopolized by overseas enterprise with roller guide shoe always, and it costs an arm and a leg, and a lot of enterprises only adopt on the high-grade elevator of high speed in the native land.For cost-cutting, and at present on the home market about 80% on elevator and new clothes elevator, adopt sliding guide shoe.The defective that sliding guide shoe exists is: must add lubricating oil on the cage guide of use sliding guide shoe, thereby surrounding environment has been caused certain pollution; Simultaneously, even added lubricating oil, the friction drag of sliding guide shoe is also very big, thereby causes the elevator power consumption big.Along with the raising of environmental protection in recent years and energy-conservation requirement, the energy consumption index of elevator also has been written in the relevant standard, and elevator should meet environmental protection and requirements of saving energy.

At present domestic also have the fixed type roller guide shoe, but the defective of its existence is: one, having now and fixedly leading boots is welded types, and geometrical variations is big, precision is low, the life-span is short, reject rate is high owing to welding deformation causes.Two, the existing welded type interface variation of fixedly leading boots makes of a great varietyly, causes the organization of production difficulty.

Summary of the invention

The invention discloses a kind of fixed type roller guide shoe, advantage such as it has, and cost is low, life-span length, compact conformation, precision are high, convenient for installation and maintenance.

The present invention takes following technical scheme: the fixed type roller guide shoe, comprise adapter plate, support, and adapter plate forms breach, and this breach is used to pass cage guide; The described support of adapter plate captive joint is installed three rollers on the described support, first roller and second roller are in same plane, and this plane and the 3rd roller plane of living in are perpendicular, and the 3rd roller plane of living in is between first roller and second roller; Corresponding between three rollers with the breach of adapter plate, be used to pass cage guide; Described adapter plate and support are spirally connected.

Preferably, described support is by base plate and one-body molded perpendicular to three risers of base plate, and three risers are installed a described roller respectively.

Preferably, described adapter plate has several mounting holes; Have on the base plate of said support and the corresponding mounting hole of adapter plate, the bottom surface of support base plate is affixed on the adapter plate, and both mounting holes are corresponding one by one, and connects through screw retention.

Preferably, after described screw passes the mounting hole of adapter plate, support base plate, be inserted in plain cushion, bullet pad, the nut of screwing again.

Preferably, the riser of said support has the waist hole; Be pressed into bearing in the bearing hole of said roller, the circlip of packing into outside the bearing, after bearing pin passes the waist hole of circlip, bearing, spacer, support riser successively, second nut that spins again, the spacer both ends of the surface peak at a side of roller, support riser respectively; The riser of support also forms perforation, and described perforation extends to corresponding waist hole, described perforation second screw that spins, and the inner end surface of second screw can the roof pressure bearing pin.

Preferably, described bearing pin is inserted in described second nut that spins again behind second plain cushion, the second bullet pad.

Fixed type roller guide shoe of the present invention has the precision height, intensity is big, manufacturability is strong, be prone to tissue production, the stock reduces, the life-span is long, integrated cost is low, compact conformation, advantage such as convenient for installation and maintenance.

The specific embodiment

Below in conjunction with accompanying drawing the embodiment of the invention is elaborated.

Referring to Fig. 1-8, adapter plate 6 forms rectangular indentation 6-1 near the edge part, and this breach is used to pass cage guide.Also have several mounting holes 6-2 on the adapter plate 6, wherein three holes are used for Mount support 7.Support 7 is by base plate 7-1 and one-body molded perpendicular to three risers of base plate, and wherein two riser 7-2 are in the same plane, and perpendicular with plane, another riser 7-3 place, and the plane at this another riser 7-3 place is between aforesaid two risers.Have on the base plate 7-1 of support and adapter plate 6 corresponding hole 7-1-1, the bottom surface of support base plate 7-1 is affixed on the adapter plate 6, and both mounting holes are corresponding one by one; And through the screw retention connection; The fixed connection structure of this three places mounting hole is identical: screw 5 stretches into from the bottom surface (through mounting hole 6-2) of adapter plate 6, and after passing the mounting hole 7-1-1 of support base plate, is inserted in plain cushion 8, bullet pad 9 from top to down; The nut 10 of screwing again, thereby with both fixed installations.

Three risers of support 7 are installed a roller respectively; Three rollers are two respectively and are in conplane horizontal roller and another vertical roller; Three rollers are identical with the mounting structure of support, the wherein structure at a place are detailed below: have a waist hole 7-2-1 on the riser 7-2.Be pressed into bearing 1 in the bearing hole of roller 2; The bearing outside circlip 3 of packing into, bearing pin 4 penetrates from a side of circlip 3, pass the waist hole 7-2-1 of circlip 3, bearing 1, spacer 11, riser successively after; Be inserted in plain cushion 12, bullet pad 13; The nut 14 that spins again, spacer 11 parts are inserted in the bearing hole of roller, and the other end peaks at a side of riser.Also form a perforation 7-2-2 on the riser 7-2, this perforation extends to waist hole 7-2-1 from the outside, and perpendicular with bearing pin 4.Screw 15 stretches into this perforation 7-2-2 from the outside, the inner of screw 15 nut 16 that spins, and inner end surface is over against bearing pin 4 and can roof pressure bearing pin 4.Below, space between three rollers is over against the breach 6-1 of adapter plate 6, and cage guide passes the breach that reaches adapter plate between three rollers, and the wheel face of three rollers gently pastes cage guide.

Horizontal dress 15mm roller assembly (about each 1), vertically adorn 6mm roller assembly, installation step:

1, earlier bearing 1 is pressed in the bearing hole of roller 2, reinstalls 35 circlip for bores 3, be pressed into bearing pin 4 then.Specification requirement by roller is assembled into three roller assemblies.

2, M10 screw 5 is put into frock, aims at mounting hole and put adapter plate 6 and support 7, again flat gasket 8, bullet pad 9 are inserted in screw 5, after be screwed into nut 10.

3, base plate and support are put into frock, locate and compress with groove and bottom.

4, spacer 11 is inserted in the bearing pin 4 of step 1, rear pin shaft 4 passes support, is inserted in flat gasket 12, spring washer 13, nut (M12) 14 again.

5, will go up two horizontal rollers that the step assembles and vertically roller gently paste cage guide, adjust the contact force of roller and cage guide through screwing corresponding M 5 screws 15 separately, tighten M12 nut 14 after adjusting.

More than the preferred embodiments of the present invention are specified; As far as those of ordinary skill in the art; According to thought provided by the invention, the part that on the specific embodiment of the present invention and field of application, all can change, and these changes also should be regarded as protection scope of the present invention.This description should not be construed as the restriction to protection domain of the present invention.
