Abstract
The invention relates to a protector for preventing a motor bearing from being damaged due to axial displacement of a motor rotating shaft in a transportation process. The protector is of a cover-shaped structure, the inner end of the protector is connected with a bearing end cover, the outer end of the protector is stretched out to the outer side of the outer end surface of the motor rotating shaft, fixing holes are formed at the corresponding positions of the rotating shaft outer end and the outer end cover of the protector, detachable fasteners are penetrated into the fixing holes, the protector is composed of two transverse parts connected with the bearing end cover and longitudinal parts connected with the two transverse parts, the longitudinal parts are capable of moving on the two transverse parts, and the fixing holes are formed on the longitudinal parts. The protector provided by the invention can regulate the position of the rotating shaft and has dual functions of protecting the bearing and regulating the position of the rotating shaft.
Description
Technical field
The present invention relates to a kind of bearing of motor that prevents and in transportation, cause the protector of its damage because of the motor rotary shaft axial endplay.
Background technology
For adopting the rolling bearing threephase asynchronous; In transportation; If do not take the measure of bearing protection; Rotor axial moves the damage that the impact of bearing is caused the bearing inner race raceway, causes the user to cause that in test run or running motor oscillating is big, bearing heating, more seriously causes bearing to burn out locking.
For the threephase asynchronous that adopts sliding bearing, its bearing arrangement and rolling bearing structure have a great difference, adopt the threephase asynchronous of sliding bearing; Its rotor has certain axial movement value; Monolateral 3～the 6mm that is generally, if in transportation, do not adopt the measure of bearing protection, rotor axial moves Sliding bush end face and rotating shaft shoulder block is frequently clashed into; Cause local deformation, influence bearing life.
The patent No. is that 200720100710.7 patent provides a kind of structure for this reason; This structure is through the locking of countershaft in transportation; Thereby reach the purpose that the protection bearing is not damaged; But this kind structure is difficult to readjust the position of rotating shaft when machine operation, so might bring influence to the service behaviour of motor.
Summary of the invention
The present invention is directed to above-mentioned defective, it is a kind of in transportation that purpose is to provide, restriction rotating shaft axial endplay and can adjust the protector of rotating shaft position.
The technical scheme of the present invention's employing is for this reason: the present invention is a hood-shaped structure; Its inner is connected on the bearing (ball) cover; The outer end extends out to the outside of motor rotary shaft outer face; Said rotating shaft outer end and protector outer end cap correspondence position are provided with fixing hole, are equipped with dismountable securing member on the fixing hole; Said protector is made up of with the vertical portion that is connected on two transverse parts two transverse parts that are connected on the bearing (ball) cover, and said vertical portion can move on two transverse parts, and said fixing hole is arranged in the said vertical portion.
Advantage of the present invention is: the present invention locks rotating shaft through bolt in transportation, thereby avoids in transportation avoiding the damage of bearing because of the rotating shaft axial endplay causes the bump to bearing and associated components, improves the useful life of bearing; The present invention simultaneously also is provided with rotation shaft regulated device, and the adjustment through rotation shaft regulated device makes the arrival assigned address that rotating shaft can be correct when work; So protector of the present invention has the dual-use function of bearing protection, rotating shaft position adjusting concurrently.
Description of drawings
Fig. 1 is applied in the structural representation on the rolling bearing for the present invention.
Fig. 2 is applied in the structural representation on the sliding bearing for the present invention.
1 is that rolling bearing, 2 is that bearing (ball) cover, 3 is that bearing protector, 4 is that bolt, 5 is that stud, 6 is that bearing shell, 7 is that axial shoulder block, 8 is that nut, 9 is a channel-section steel among the figure.
Embodiment
For rolling bearing: bearing protector 3 one ends are connected on the bearing (ball) cover 2; The other end stretches out the rotating shaft outer face and leaves the gap, and there are two screwed holes the rotating shaft outer face, after bolt 4 is screwed; Rotating shaft is drawn out; Make rolling bearing 1 vertically by locked, therefore, the loosening of bearing enclose can not take place and damage rolling bearing 1 in transportation.
For sliding bearing: the removal hole that stud 5 screws on the bearing (ball) covers 2; The other end links to each other with channel-section steel 9; Channel-section steel 9 central authorities are equipped with two bolts 4; After two bolts hole in middle part through channel-section steel 9 screw in two screwed holes of rotating shaft outer end, rotating shaft is pulled out locked, prevent the play two of rotating shaft and cause bearing shell 6, the axial frequent bump of parts such as shoulder block 7.After motor is transported to the user simultaneously, also can the installation that correct magnetic center position is beneficial to the user be pushed up in rotating shaft through adjustment nut 8.
Claims (1)
1. anti-bearing of motor damages protector, is a hood-shaped structure, and its inner is connected on the bearing (ball) cover; The outer end extends out to the outside of motor rotary shaft outer face, and said rotating shaft outer end and protector outer end cap correspondence position are provided with fixing hole, are equipped with dismountable securing member on the fixing hole; It is characterized in that; Said protector is made up of with the vertical portion that is connected on two transverse parts two transverse parts that are connected on the bearing (ball) cover, and said vertical portion can move on two transverse parts, and said fixing hole is arranged in the said vertical portion.
