Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

As shown in fig. 1-4, a motor bearing fixing seat with dustproof effect, includes U shaped support plate 1, base 2, lower shield 4, and horizontal and fixed mounting in two base 2 upper surfaces in U shaped support plate 1 bottom, and lower shield 4 fixed mounting is inboard in U shaped support plate 1, and the equal fixed mounting in both sides of lower shield 4 has connecting block 8, and both sides connecting block 8 passes through under shield 4 and the last shield 3 of bolt 9 fixed connection.

Wherein, two base 2 upper surface both ends all are provided with spacing hole 10, fix base 2 inside the motor through spacing hole 10, the connecting block 8 of 4 both sides of lower shield is located 1 tops of U type backup pad, and with 1 top fixed connection of U type backup pad, both sides connecting block 8 all through bolt 9 swing joint, with

upper shield

3 and 4 fixed connection of lower shield, shield both sides baffle can prevent effectively that dust or debris from getting into inside the bearing, influence the bearing operation.

When the oil injection device is specifically arranged, the oil injection hole 16 is formed in the middle of one side of the upper dustproof cover 3, the oil hole cover 11 is movably mounted on one side of the upper dustproof cover 3 on the outer side of the oil injection hole 16, and the oil injection hole 16 and the bearing ball 14 are located on the same horizontal position, so that oil can be conveniently injected into the bearing.

The bottom end of the oil hole cover 11 is movably connected with the upper dust cover 3 through a hinge 12, a round bump is arranged at one end, close to the bearing, inside the oil hole cover 11, the bump is tightly attached to the oil filling hole 16, the oil filling hole 16 is covered through the oil hole cover 11 after oil filling is completed, and oil is prevented from splashing out of the oil filling hole 16 when the bearing operates.

Go up 3 top middle parts fixed mounting of shield and have pull ring base 7, pull ring base 7 has pull ring 6 for round platform form and upper end run through, conveniently takes and adjusts the position of shield 3.

Go up shield 3 and the inside U type notch 17 of all having seted up of lower shield 4, and go up shield 3 and the equal fixed mounting of 4 inner walls of lower shield has the same rubber circle 13 of size, the rubber circle 13 is kept away from the one end of last shield 3 and lower shield 4 and is all laminated with bearing inner race 15, bearing ball 14 evenly distributed is at bearing inner race 15 and bearing inner race 5 middle part, the laminating of bearing inner race 5 inner wall keeps away from the one end of rubber circle 13 on U type notch 17, it is located U type backup pad 1 both sides top and on the coplanar to go up shield 3 and lower shield 4 junction, because the bearing is likely to take place bearing inner race 15 along with the slight pivoted condition of bearing inner race 5 when long-time operation, set up rubber circle 13 at bearing inner race 15, through the frictional force between rubber circle 13 and bearing inner race 15, thereby the position of fixed bearing inner race 15.

This motor bearing fixing base's theory of operation with dustproof effect:

when the bearing is fixed, firstly, the bolt 9 in the connecting block 8 is rotated, the upper dustproof cover 3 is separated from the lower dustproof cover 4 by pulling and lifting the pull ring 6, then the bearing is placed into the U-shaped notch 17 of the lower dustproof cover 4, the bearing outer ring 15 is pressed on the rubber ring 13 fixed on the inner wall of the lower dustproof cover 4, then the U-shaped notch 17 of the upper dustproof cover 3 is aligned to the upper side bearing cover, so that the rubber ring 13 on the inner wall of the upper dustproof cover 3 also presses the bearing outer ring 15, then the bolt 9 is placed into the connecting block 8 to be screwed, because of friction between the rubber ring 13 and the bearing outer ring 15, the bearing outer ring 15 can not slightly slide along with the bearing balls 14 and is better fixed in the bearing fixing seat, when the bearing is arranged, the lower dustproof cover 4 is fixedly arranged on the inner wall of the U-shaped supporting plate 1, the bottom end of the U-shaped supporting plate 1 is fixed on the upper surfaces of the two bases 2, the fixing base 2 is fixed in the motor through the limiting hole 10, when the bearing needs oiling, open oil hole lid 11, put into the bearing with the glib talker through oil filler point 16 inside, after the oiling, close oil hole lid 11, oil is from oil filler point 16 spill when avoiding the bearing operation, also prevents simultaneously that outside dust or debris from getting into inside the bearing, influences the operation of bearing.
