Description

One kind swashs pendulum device

Technical field

The utility model is related to a kind of sharp pendulum device.

Background technology

Swash pendulum device, i.e., cause that equipment produces a kind of mechanical structure of omnidirectional's swing by external force.Current existing sharp pendulum device Axially smaller stress and radial force can only be realized.Some can simultaneously realize larger axially loaded and radial force, But changed by temperature and the prolonged ratio using bearing outside after abrasion and roller clearance change is larger so that bearing life Shorten serious.

Bearing is all used in many places of mechanical manufacturing field, but it is unbalanced or for vibrating effect due to what is loaded Need so that bearing inner sleeve is in crash situation with overcoat, and this have impact on the service life of bearing.

If so that inside and outside when rotated the covering of bearing is in close contact state all the time, the service life of bearing can obtain Extension.

Utility model content

In view of situation above, in order to solve the problems, such as above-mentioned technology, pendulum device is swashed the utility model proposes one kind, including The clutch shaft bearing and second bearing being fixed in bearing chamber, and the axle in clutch shaft bearing and second bearing, first axle The lower section held is provided with the first inner cap, and the second inner cap is provided with above second bearing, and spring, institute are provided with below the second bearing The upper end for stating spring contacts with the inner ring of the second bearing, and the lower end of the spring contacts with the round nut being mounted on an axle.

In pendulum device is swashed according to one kind of the utility model embodiment, it is preferable that the top fixed installation of the bearing chamber First gland, the lower section of the bearing chamber fixedly mounts the second gland.

In pendulum device is swashed according to one kind of the utility model embodiment, it is preferable that described round nut and described second Stop washer is provided between gland.

In pendulum device is swashed according to one kind of the utility model embodiment, it is preferable that described axle upper end spindle nose fixed installation Eccentric block, described axle lower end spindle nose fixed installation eccentric wheel.

Take the utility model proposes technology after, according to the sharp pendulum device of the utility model embodiment, axle, clutch shaft bearing It is locked in bearing chamber by nut and spring with second bearing.If the pressure for having axial impact load, spring should be greater than load Impulsive force, if there is impact load radially, the pressure of spring should be greater than impact load component in the axial direction.If axially There is impact load with radial direction, then the pressure of spring should be greater than their superposed forces in the axial direction.If temperature is raised causes shaft extension Long, the outer ring of clutch shaft bearing and second bearing becomes big, and spring can automatically eliminate the gap of generation.The other case can also eliminate the The gap that one bearing and second bearing abrasion are produced, so that clutch shaft bearing and second bearing will not be vibrated because there is gap, keeps away Clutch shaft bearing and the too fast damage of second bearing are exempted from.

Take the utility model proposes technology after, according to the sharp pendulum device of the utility model embodiment, eliminate bearing Gap between inside and outside set, it is to avoid gap occur and cause vibrations, so as to extend bearing service life.Can realize simultaneously larger Axially loaded and radially (two-way) stress, do not rung by the shaft extension epitome under temperature variations, and can significantly extend bearing Life-span.The sharp pendulum device can be eliminated because of the gap that temperature and abrasion cause, and makes bearing roller that a perseverance substantially is maintained to overcoat Fixed rational pretightning force.The structure also helps the sealing and dismounting of bearing chamber.In general, according to the utility model embodiment Sharp pendulum device, improve service life of equipment, reduce operation noise, reduce running temperature, improve stable equipment operation Property.Facilitate maintenance maintenance.

Specific embodiment

Of the present utility model each is preferred embodiment described below with reference to accompanying drawings.There is provided referring to attached The description of figure, to help the understanding to the example embodiment of the present utility model limited by appended claims and their equivalents. It includes the various details for helping understand, but they can only be counted as it is exemplary.Therefore, those skilled in the art will Recognize, implementation method described herein can be made various changes and modifications, without deviating from scope of the present utility model and essence God.And, in order that specification is more clear succinct, will omit pair it is well known that the detailed description of function and construction.

As shown in figure 1, a kind of swash pendulum device, including it is fixed on clutch shaft bearing 4 and second bearing 8, Yi Jian in bearing chamber 6 Axle 2 in clutch shaft bearing 4 and second bearing 8, the lower section of clutch shaft bearing 4 is provided with the first inner cap 5, the top of second bearing 8 The second inner cap 7 is provided with, the lower section of the second bearing 8 is provided with spring 9, in the upper end of the spring 9 and the second bearing 8 Circle contact, the lower end of the spring 9 contacts with the round nut 10 on axle 2.

Swash pendulum device as according to one kind of the utility model embodiment, the top fixed installation first of the bearing chamber 6 is pressed Lid 3, the lower section of the bearing chamber 6 fixedly mounts the second gland 11.

Swash pendulum device, described round nut 10 and the second described gland 11 as according to one kind of the utility model embodiment Between be provided with stop washer 13.

Swash pendulum device, the described upper end spindle nose fixed installation eccentric block of axle 2 as according to one kind of the utility model embodiment 1, the described lower end spindle nose fixed installation eccentric wheel 12 of axle 2.

Pendulum device is swashed as according to one kind of the utility model embodiment, by axle 2, clutch shaft bearing 4 and second bearing 8 by spiral shell Mother 10 and spring 9 are locked in bearing chamber 6.If there is axial impact load, the pressure of spring 9 should be greater than the impulsive force of load, If there is impact load radially, the pressure of spring 9 should be greater than impact load component in the axial direction.If axially and radially having Impact load, then the pressure of spring 5 should be greater than their superposed forces in the axial direction.If temperature is raised causes that axle 2 extends, first axle Hold 4 and the outer ring of second bearing 8 become big, spring 9 can automatically eliminate the gap of generation.The other case can also eliminate clutch shaft bearing 4 and second bearing 8 abrasion produce gap so that clutch shaft bearing 4 and second bearing 8 will not be vibrated because there is gap, it is to avoid Clutch shaft bearing 4 and the too fast damage of second bearing 8.

According to the sharp pendulum device of above-mentioned the utility model one embodiment, the gap between the inside and outside set of bearing is eliminated, it is to avoid There is gap and cause vibrations, so as to extend bearing service life.Larger axially loaded and radial direction (two-way) can simultaneously be realized Stress, is not rung, and can significantly extend bearing life by the shaft extension epitome under temperature variations.The sharp pendulum device can be eliminated Because of the gap that temperature and abrasion cause, and bearing roller is set to maintain a rational pretightning force of substantially constant to overcoat.The structure Also help the sealing and dismounting of bearing chamber.In general, according to the sharp pendulum device of the utility model embodiment, the equipment of improve makes With the life-span, operation noise is reduced, reduce running temperature, improve stable equipment operation.Facilitate maintenance maintenance.
