Abstract
The utility model discloses a single-beam crane drive wheel device, which comprises a wheel shaft, a drive wheel and a deep ditch ball bearing, wherein the drive wheel is arranged in an end beam, the wheel shaft penetrates through the end beam and the deep ditch ball bearing, and one end of the wheel shaft is fixedly connected with the outer side of the end beam through a clamp board. The drive wheel is supported on the wheel shaft through the deep ditch ball bearing, and two ends of the end beam are supported on a track through the drive wheel. The deep ditch ball bearing is arranged in two end surfaces of the deep ditch ball bearing, the edge of a retaining edge on one end of the drive wheel is provided with a last stage drive gear. The single-beam crane drive wheel device integrates the last stage drive gear and the drive wheel, reduces the number of fittings of the drive wheel device to 5 from 11, lowers the manufacture cost, and improves the problem of big noise when an original crane is running under no load.
Description
Technical field
The utility model relates to a kind of cart walking mechanism of crane in bridge type, and particularly a kind of drive wheel mechanism that is arranged on the end carriage belongs to the elevator machinery technical field.
Background technology
At present, the crane in bridge type especially transmission of bridge-type single-beam crane end carriage adhesion wheel device adopts final stage transmission gear and adhesion wheel axial restraint ways of connecting, the motor via reducer multi-stage speed-reducing transmission of end carriage actuating device, drive adhesion wheel by the final stage transmission gear at last and roll, thereby crane end carriage is moved forward and backward along crane track along crane track.There is following problem in this type of drive:
1. because many parts such as spacer are housed in the adhesion wheel, the noise when causing the hoisting crane no-load run is up to 65～75 decibels.
2. because the final stage transmission gear adopts fastener to be axially fixed in the end face of adhesion wheel, period of service is of a specified duration, and that fastener can produce is loosening, causes the engagement of final stage transmission gear bad, influences large vehicle walking.
The utility model content
Noise is big when solving the operation that existing single-beam crane adhesion wheel device exists, the engagement of final stage transmission gear is bad, influence the defective of large vehicle walking, the utility model proposes a kind of adhesion wheel device of single-beam crane, noise when this adhesion wheel device can reduce operation effectively guarantees that the engagement of final stage transmission gear is good.
The utility model is achieved by the following technical programs.
A kind of single-beam crane adhesion wheel device comprises axletree, adhesion wheel, deep groove ball bearing.Described adhesion wheel is arranged in the end carriage, and described axletree passes end carriage, deep groove ball bearing, and the one end is captiveed joint with the end carriage outside by clamp.Described adhesion wheel is bearing on the axletree by deep groove ball bearing, and the two ends of described end carriage by the adhesion wheel supporting in orbit.Described deep groove ball bearing is arranged in the both ends of the surface of adhesion wheel, and the rib edge of described adhesion wheel one end is provided with the final stage transmission gear.
The utlity model has following beneficial effect:
1. the power of motor of end carriage actuating device drops to 0.75kW from 1.5kW, and energy-saving effect is remarkable.
2. the adhesion wheel device is integrated final stage transmission gear and adhesion wheel, and the number of parts that makes the adhesion wheel device reduces to 5 from 11, has reduced manufacturing cost.
Noise during the hoisting crane no-load run from 65～75 decibels reduce to≤25 decibels, improved the big problem of original noise.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the structural representation of existing adhesion wheel device;
Fig. 2 is the structural representation of adhesion wheel device of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, existing adhesion wheel device is made up of back-up ring 1, deep groove ball bearing 2, adhesion wheel 3, axletree 4, screw 6, cover 7, spacer 8, oil nozzle 9, gear ring 10, baffle plate 11.Axletree 4 passes end carriage 5, is arranged on the deep groove ball bearing 2 of adhesion wheel 3 both sides, the one end is captiveed joint with end carriage 5 by clamp 1, deep groove ball bearing 2 is separately positioned on the both sides of adhesion wheel 3, adhesion wheel 3 is bearing on the axletree 4 by deep groove ball bearing 2, cover 7 is arranged between baffle plate 11 and the deep groove ball bearing 2, and is spacing to the inner ring of deep groove ball bearing 2; Spacer 8 is arranged between the outer ring of deep groove ball bearing 2, to the outer ring inner side limiting-position of deep groove ball bearing 2; Oil nozzle 9 is provided with an end of axletree 4, is used for deep groove ball bearing 2 filling lubricating oils; Deep groove ball bearing 2 outsides are spacing with baffle plate 11, and a plurality of screws 6 of gear ring 10 usefulness are fixed on the adhesion wheel 3 axial sides.This constructional delails quantity is many, and adhesion wheel 3 operation noises are big.
The utility model comprises axletree 4, adhesion wheel 3, deep groove ball bearing 2, adhesion wheel 3 is arranged in the end carriage 5, axletree 4 passes end carriage 5, deep groove ball bearing 2, the one end is captiveed joint with end carriage 5 outsides by clamp 1, adhesion wheel 3 is bearing on the axletree 4 by deep groove ball bearing 2, and the two ends of end carriage 5 by adhesion wheel 3 supportings in orbit.Deep groove ball bearing 2 is arranged in the both ends of the surface of adhesion wheel 3, and the rib edge of adhesion wheel 3 one ends is provided with final stage transmission gear 31.
The utility model is integrated final stage transmission gear and adhesion wheel, has reduced the quantity of part, and the noise when having reduced the hoisting crane no-load run has reduced manufacturing cost.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
