Description

The weaving loom rapier transmission box

Technical field

The utility model discloses a kind of weaving loom rapier transmission box, specifically belong to the rotatable parts of textile rapier loom.

Background technology

The conventional at present rapier transmission box of using, comprise cabinet shell 1, driving shaft 3, driven axle 2, main spiral bevel gear wheel seat 11, driving shaft 3 is installed in the cabinet shell 1 by ball bearing 5, cylinder roller bearing 6,2 of driven axles are installed in the cabinet shell 1 by double row ball bearing 4 and cylinder roller bearing 2, and with driving shaft 3 perpendicular installations, the spur gear 7 of body input and the power output panel 8 of output, driven axle 2 links by a pair of bevel reduction gear set on it 9,10 with driving shaft 3.

The defective of this conventional structure just is: driven axle 2 is installed in cylinder roller bearing 2 places with the connecting place of driving shaft 3, because be subjected to the restriction of inner housing construction like this, makes the body inner chamber that the bigger bearing of ability to bear can not be installed; The distance of the two bearings strong point is shorter on the driven axle 2, can not bear the impact of powerful axial and united power.In addition, can be gapped when driving bevel gear seat 11 moves with being engaged in of casing 1, and can be increasing, the bearing of rapier transmission box is in Rapier looms high speed back and forth movement process so, such housing construction, just can not bear and run up, can't guarantee the operation that the rapier transmission box body is normal, stable for a long time, directly influence the work operation conditions and the service life thereof of Rapier looms.

The utility model content

The utility model is at the deficiencies in the prior art, and purpose is to provide that a kind of operation is stable more, long service life, textile rapier loom rapier transmission box easy for installation.

The technical solution adopted in the utility model is: a kind of weaving loom rapier transmission box, comprise casing, driving shaft, driven axle, a pair of bevel reduction gear set, be connected by a pair of bevel reduction gear set between driving shaft and the driven axle, it is characterized in that: also comprise extending and strengthen axle, extend the reinforcement axle and be fixed with one with driven axle, and pass through front cone roller bearing, back taper roll bearing laterally through casing, driving shaft is installed in the casing by cylinder roller bearing, double-row conical bearing.

The utility model further is set to: front cone roller bearing, cylinder roller bearing are installed in respectively near a bevel gear on the driven axle and an end of the bevel gear on the driving shaft, and back taper roll bearing is installed in to cooperate with the end of extending the reinforcement axle again on the wall box and links to each other.Its role is to driven axle through lengthening, the taper roll bearing of box house stretches out and is installed on the wall box, has increased the box house space, makes the thick stick increase of bevel gear, for solid foundation has been created in the steady running of Rapier looms high speed.

The utility model further is set to again: the upper and lower plane of double-row conical bearing is held nut, adjustable bearing bearing by pressure respectively and is cooperated and link to each other, and the circumference outer ring of adjustable bearing bearing and casing inner ring and double-row conical bearing is an interference fits.Make double-row conical bearing not have the gap each other and cooperate, thereby guarantee stable, the noiselessness of body with adjustable bearing bearing and casing.

The utility model also further is set to: adjustable bearing bearing end cap limit portion is provided with jackscrew and tight silk, and tight silk links to each other with casing again.This design can be convenient to operating personnel and regulate at any time, because the body that newly assembles all can have a running-in period, promptly a pair of bevel reduction gear set on driving shaft and driven axle is carried out in the quick back and forth movement, in the course of time the situation that can occur becoming flexible, as long as regulate the jackscrew and the tight silk of adjustable bearing bearing outside bevel reduction gear set is cooperated closely, during adjusting jackscrew is withstood box body wall, then will tight silk tighten clockwise that can to make driving shaft and driven axle obtain running steady, and make bevel reduction gear set effectively bear the load that brings when body runs up.

In addition, of the present utility model being also advantageous in that: the input at driving shaft has been installed double-row conical bearing, and it also can bear bi-directional axial load when bearing radial load, can be in the end-play scope of bearing the axial displacement of restrictive axes and shell.And taper roll bearing has been installed on the driven axle, it can bear based on footpath radially, axial connected load.And the standardization of the size of taper roll bearing, have interchangeability, and installing/dismounting is very convenient, it also makes characteristics such as body when operation wearing and tearing are little.

In sum, the utlity model has that operation is stable more, the characteristics of long service life, easy installation and removal, thereby help improving the operational efficiency of rapier transmission box integral body.

The utility model is described in further detail below in conjunction with drawings and Examples:
