Abstract
This utility model relates to a kind of service life that can not only extend motor entirety, and maintenance cost is low, can effectively reduce motor simultaneously and use the reducer motor flange lid of noise, including end cap body, this internal centrage being provided with seal mounting hole and bearing mounting hole and the centrage of seal mounting hole and bearing mounting hole of described end cap overlaps with the axis hole centrage in end cap body respectively, described bearing mounting hole side is through with the "eight" shape lid mouth in end cap body, opposite side is through with seal mounting hole, 1.2 times 2.5 times of a length of oil sealing thickness of described seal mounting hole.Advantage: one is that reducer motor flange end cap not only maintenance cost is low, and service life is longer；Two is that the hole back-up ring in reducer motor flange end cap can be prevented effectively from motor and axial float occurs, thus reduces the noise of motor.
Description
Technical field
This utility model relates to a kind of service life that can not only extend motor entirety, and maintenance cost is low, can effectively reduce motor simultaneously and use the reducer motor flange lid of noise, belongs to electric motor end cap and manufactures field.
Background technology
Existing reducer motor flange lid (with reference to Fig. 1), including including end cap body 1 ', it is provided with seal mounting hole 2 ' and bearing mounting hole 3 ' in described end cap body 1 ' and between seal mounting hole 2 ' and bearing mounting hole 3 ', is provided with spacer sleeve 7 ', described spacer sleeve 7 ' separates the oil sealing being arranged in seal mounting hole 2 ' and the bearing 8 ' being arranged in bearing mounting hole 3 ', described bearing mounting hole 3 ' side is through with the "eight" shape lid mouth 5 ' in end cap body 1 ', opposite side is through with seal mounting hole 2 ' by spacer sleeve 7 ', described bearing 8 ' is arranged on bearing mounting hole 3 ' by wave washer 9 '.The centrage of the centrage of described spacer sleeve 7 ', the centrage of seal mounting hole 2 ' and bearing mounting hole 3 ' overlaps with the axis hole 4 ' centrage in end cap body 1 ' respectively.Weak point: one is that in existing reducer motor flange lid, the degree of depth of seal mounting hole and oil sealing thickness are same size, and be provided with inside seal mounting hole and to make oil sealing and bearing interval set, such design shaft part equipped with oil sealing after oil sealing and rotating shaft normal wear reduces because of abrasion size, and oil sealing is owing to there being the restriction of spacer sleeve to make oil sealing can not carry out axial dipole field, makes motor lie substantially in the state of scrapping thus greatly reduces the service life of system；In two are the bearing mounting hole that bearing passes through in wave washer existing reducer motor flange lid, easily there is axial movement of motor in such assembling structure, and then causes axial dipole field occurring between box body of speed reducer gear or producing movement tendency；Produce noise.Reduce the life-span；Simultaneously because axial float makes electric engine oil seal internal diameter increase with axis friction area, and then reduce oil sealing and the service life of whole system.Three is that outside seal mounting hole, bead exists most advanced and sophisticated position；For the reductor requiring high sealing performance, easily scratch oil seal lip so that sealing property declines or service life reduction.
Utility model content
Purpose of design: for avoiding the deficiency in background technology, designs a kind of service life that can not only extend motor entirety, and maintenance cost is low, can effectively reduce motor simultaneously and use the reducer motor flange lid of noise.
Design: for realizing above-mentioned purpose of design.1, the design of 1.2 times-2.5 times of a length of oil sealing thickness of described seal mounting hole, is one of technical characteristic of the present utility model.So purpose of design is: one is when the shaft part equipped with oil sealing because reducing (i.e. gap occur between the shaft part of oil sealing and installation oil sealing) because abrasion makes this shaft part size, oil sealing can be carried out axial dipole field, make oil sealing be reinstalled in and be positioned on the shaft part not having abrasion of seal mounting hole, thus not only reduce maintenance cost, and improve the service life of reductor system；Two is that the length set up due to seal mounting hole is minimizing or cancels the space of original spacer sleeve and obtain, and therefore without increasing the size of reducer motor flange lid, thus has saved the manufacturing cost of reducer motor flange lid.2, have the design of annular groove on described bearing mounting hole inwall, be the two of technical characteristic of the present utility model.So purpose of design is: have annular groove on described bearing mounting hole inwall for installing hole back-up ring, hole back-up ring can be prevented effectively from motor and axial float occurs, in so avoiding the noise that produces because axial float makes to occur between box body of speed reducer gear axial dipole field, it also avoid simultaneously and reduce the service life of reductor system because axial float makes the friction area between oil sealing internal diameter and machine shaft become big.3, the design of the bead rounding of described seal mounting hole outboard end, is the three of technical characteristic of the present utility model.So purpose of design is: the bead rounding of described seal mounting hole outboard end so that oil sealing coordinates face and bead rounding off, this avoid and makes because oil seal lip is scratched the sealing property of oil sealing decline or the reduction in service life of oil sealing.
Technical scheme: a kind of reducer motor flange lid, including end cap body, this internal centrage being provided with seal mounting hole and bearing mounting hole and the centrage of seal mounting hole and bearing mounting hole of described end cap overlaps with the axis hole centrage in end cap body respectively, described bearing mounting hole side is through with the "eight" shape lid mouth in end cap body, opposite side is through with seal mounting hole, 1.2 times-2.5 times of a length of oil sealing thickness of described seal mounting hole.
This utility model is compared with background technology, and one is that reducer motor flange end cap not only maintenance cost is low, and service life is longer；Two is that the hole back-up ring in reducer motor flange end cap can be prevented effectively from motor and axial float occurs, thus reduces the noise of motor.

Detailed description of the invention
Embodiment 1: referring to the drawings 2.A kind of reducer motor flange lid, including end cap body 1, the centrage being provided with seal mounting hole 2 and bearing mounting hole 3 and the centrage of seal mounting hole 2 and bearing mounting hole 3 in described end cap body 1 overlaps with axis hole 4 centrage in end cap body 1 respectively, described bearing mounting hole 3 side is through with the "eight" shape lid mouth 5 in end cap body 1, opposite side is through with seal mounting hole 2,1.2 times-2.5 times of a length of oil sealing thickness of described seal mounting hole 2.Have annular groove 6 on described bearing mounting hole 3 inwall and annular groove 6 is located close in the bearing mounting hole 3 of "eight" shape lid mouth 5 side.The size of described annular groove 6 is mated with the size of hole back-up ring 9.The diameter of described bearing mounting hole 3 mates with the outside diameter of bearing 8.Bead 7 rounding of described seal mounting hole 2 outboard end.The diameter of described bearing mounting hole 3 is more than the diameter of axis hole 4 more than the diameter of seal mounting hole 2 and the diameter of seal mounting hole 2.
It is to be understood that: although the word that mentality of designing of the present utility model is contrasted detailed by above-described embodiment describes; but these words describe; simply the simple text of this utility model mentality of designing is described; rather than the restriction to this utility model mentality of designing; any combination without departing from this utility model mentality of designing, increase or revise, each falling within protection domain of the present utility model.
