Abstract

The present invention relates to a connection and arrangement structure for connecting a heald frame and a frame drive. Concretely, the structure comprises a frame connection device provided with a connection device half body comprising a bearing and a connector. The bearing and the connector can be separated from a bearing carrier, and the bearing carrier can be rigidly connected with the heald frame. The connector and the bearing are optionally connected with the bearing carrier via a threaded connection device and thus can be separately replaced. Therefore, the connector and the bearing can be replaced in a simple manner so as to maintain the frame connection device. Complicated lubrication arrangement structures, especially lubrication arrangements and so on, can be omitted. Operation of the frame connection device is also simplified, especially when the connection devices are bonded together. When doing this, rotating positions of the connecting piece in an outer hexagonal shape do not matter. Therefore, assembly errors during arrangement of the connecting piece and grease lubrication arrangements can be avoided.

Description

For the connection arrangement that heald frame is connected with the frame driver

Background technology

This type of connects arrangement also referred to as the frame coupling.

Be used for the frame coupling of heald frame for example from publication US 4,541,459th, known.This type of frame coupling is arranged to the vertical up and down actuation movement of actuated lever assemblies is delivered to the heald frame of vertical movement.In addition, also should discharge when needed the frame coupling.In order to complete this point, described US 4,541,459 provides the several bearing carriers on the heald frame, and described bearing carrier is constructed to by a pair of cheek of screw fastening and dowel is remained between them.Ring with hexagon outside is seated on dowel, and described ring can rotate on dowel.In view of hexagonal rings has formed frame side coupling halfbody, the frame coupling comprises the drive-side coupling halfbody of the degree of lip-rounding part form that is provided with stick.

Have been found that the ring with hexagon outside stands two kinds of wear phenomenons in the continued operation process of heald frame.Especially, this ring needs lubricated fully.If do not carry out sufficient lubrication, will change prematurely the coupling halfbody of damaged.In order to do like this, usually change whole bearing carrier (comprising hexagonal rings), described ring forms connector.

Publication DE 601 33 753 T2 disclose the frame coupling that similarly comprises hexagonal rings, and this hexagonal rings still supports by being maintained at two axles between cheek.Ring is made by the selflubricatingpiston material.In addition, can provide the lubricating utensil of grease lubrication device form, it radially is applied to hexagonal rings.

Again, in the situation that wearing and tearing must be changed the whole coupling halfbody that comprises cheek, axle and hexagonal rings.

Even lubricated is fully, but the wearing and tearing of frame side coupling halfbody are also obvious.If lubricated insufficient, wearing and tearing increase.

Summary of the invention

Therefore, the object of the invention is to promote the maintenance of frame coupling and allow to keep in repair as required.

Realize this purpose by connection arrangement according to claim 1.

Connection arrangement according to the present invention comprises the bearing carrier that will be connected to heald frame, and described bearing carrier keeps a bearing, is used for rotatably supporting connector.The device that bearing carrier and bearing are disposed between bearing carrier and bearing is threaded onto together, in order to bearing is remained on the bearing carrier.Screw connection can be released as required.Change passage and be limited on the bearing carrier, connector and bearing thereof (in the d/d situation of screw connection) can pass during this replacing passage is directed out the bearing carrier and again gets back to the bearing carrier.This is possible, and any other operation that need to be on the bearing carrier, for example crooked, dismounting or similar action.For example, if the bearing carrier comprises two cheeks that are retained an apart distance, the plane surface of two positioned opposite by described cheek forms the replacing passage.When screw connection is released, bearing and connector can be between plane surface transversely the direction in bearing axis be drawn out.Plane surface may not prevent the barrier that bearing and connector are drawn out such as rib, exoncoma, projection (bead).

Therefore, connector and bearing can be as required separate and can be replaced as required from the bearing carrier.Do not need the bearing carrier is separated from heald frame.This provides the chance of connection bearing carrier and frame bar or side support member securely, and need to not abandon and change frame bar or side support member when connector and bearing wear.

Screw connection shows the maintenance interface for connector.

The bearing carrier comprises at least one cheek, preferably includes two cheeks that are retained apart parallel relative distance, and thus, bearing and connector are maintained between described cheek.Preferably, it is at least substantially flat that cheek is faced on the side of bearing at them, thereby when screw connection is released, connector and bearing can be pulled out between cheek.Preferably, cheek is also at least substantially flat on their outside.Screw connection for example comprises at least one screw and a nut, preferably have on screw and nut on head, described head sinks in described cheek.Head can have same size or have different size.They can or also can have different shapes about the mirror images of each other symmetry.

Preferably, have taper shape or step opening for the cheek that holds a head, it receives the head of complementary shape accordingly.At least one in the opening of two cheeks has circular contour, in order to allow the rotation of head separately.Opening in another cheek can be also circular, can also be randomly perhaps non-circular, for example square or hexagon, thus prevent the rotation of screw head separately or nut head.Alternatively, also can prevent or stop by the form fit locking device the common rotation of screw head or nut head, described form fit locking device is for example rib on the adjacent contact surfaces of cheek and screw head or nut head.

Preferably, screw connection medially extends through bearing, and described bearing has the through hole corresponding with it.Alternatively, bearing self can have screwed hole, for example screw can be screwed into this screwed hole from both sides, and again, the head of described screw sinks in cheek.Other remodeling are also possible.Preferably, bearing is the ring with cylindrical outer surface, and connector rotatably is seated on this cylindrical outer surface with minimal gap.Preferably, connector is made of self-lubricating material, for example the self-lubricating bronze.

The axial length of bearing is preferably more than the axial length of connector.Therefore, the cheek of bearing carrier provides the axial restraint of connector, connector otherwise be seated on bearing in the mode that can rotate freely.

Consider remodeling embodiment, only provide single cheek, described cheek loading bearing.Bearing can be provided with cranse (for example, radial flange) at it on the side away from cheek, so that fixed coupling unit axially.

Preferably, connector is ring, this ring has the hexagon outside, namely has six planes, and described six planes are same size preferably.Preferably, this ring is closed on its whole periphery, that is, it had not both had lubrication hole there is no lubricating nozzle yet.Therefore, it can engage with other coupling halfbodies formation on six different position of rotation basically.The wearing and tearing that occur on the whole periphery of this permission with connector distribute, and this and then help increase its actuation time.
