Abstract
The utility model discloses an auxiliary press-fitting tool for an oil seal and relates to an auxiliary press-fitting tool for the oil seal on a rear bearing cover of an output shaft of a gearbox assembly. By the aid of the auxiliary press-fitting tool, the problem of oil leakage caused by damage of lips of oil seals or tilting of the oil seals during assembly of the oil seals due to the fact that no positioning relationship exists among the oil seals, rear bearing covers and auxiliary press-fitting tools during press fitting caused by the fact that the known press fitting of the oil seals on the rear bearing covers of output shafts of gearbox assemblies is achieved by pressing the oil seals into the rear bearing covers through pressure heads by press machines is solved. According to the auxiliary press-fitting tool, a pressing sleeve is arranged at the upper end of a positioning column and connected with a positioning sleeve. According to the auxiliary press-fitting tool, the oil seal is prevented from inclining during press fitting due to a positioning reference and prevented from being damaged due to position limiting, and the problem of the oil leakage of the oil seal is solved.
Description
Technical field
The utility model relates to a kind of oil sealing and press-fits accessory, relates to the accessory that press-fits that the transmission assembly rear bearing, output shaft covers oil sealing particularly.
Background technology
Known transmission assembly is covered 2 places at rear bearing, output shaft 1 oil sealing 3 is housed, as shown in Figure 1, this oil sealing 3 is pressed in rear bearing cover 2 holes at forcing press, but exist oil sealing 3 to press-fit problems such as inclination always, cause from oil sealing 3 leakage of oils, the reason of leakage of oil is to press-fit accessory to have design defect, at present, the assemble sequence of oil sealing is: the top that earlier oil sealing 3 freely is placed on rear bearing cover 2, again pressure head 7 is put into the hole of oil sealing 3, from the top with forcing press toward being pushed down into oil sealing 3, in this process, because oil sealing 3, rear bearing cover 2 and press-fit no any positioning relation between the accessory causes oil sealing 3 lip limit breakages or oil sealing to tilt and causes leakage of oil in oil sealing 3 assembling processes.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and that a kind of oil sealing that proposes press-fits is smooth, avoids oil sealing to press-fit and is not damaged by pressure, and the oil sealing that reduces oil leakage phenomenon press-fits accessory.
Technical solution of the present utility model is: oil sealing press-fits accessory and is: the upper end of reference column is provided with gland, is connected with positioning sleeve on the gland.
Gland described in the technical solution of the present utility model and positioning sleeve all be one inverse-T-shaped, positioning sleeve is connected as a whole by screw with gland.
Positioning sleeve described in the technical solution of the present utility model is provided with the endoporus that is complementary with oil sealing.
Because the assembling accessory design defect of oil sealing directly influences whole transmission assembly total quality, press-fit accessory by oil sealing of the present utility model, after operator on the assembly line uses, oil sealing press-fits smooth, oil leakage phenomenon significantly reduces, the utility model is 1. owing to there being the location benchmark to guarantee that oil sealing can press-fit, 2. owing to there is spacing assurance oil sealing can not damaged by pressure.Thereby solved oil sealing and press-fited the problem that tilts to cause the leakage of oil of oil sealing place.

The specific embodiment
As Fig. 2,3,4, shown in 5, oil sealing of the present utility model press-fits accessory by reference column 1, positioning sleeve 4 and gland 5 are formed, the upper end of reference column 1 is provided with positioning sleeve 4 and gland 5, the diameter of the endoporus of gland 5 and reference column 1 upper end is complementary and is installed on the reference column 1, be provided with positioning sleeve 4 at gland 5, positioning sleeve 4 and gland 5 all be one inverse-T-shaped, the external diameter of positioning sleeve 4 and gland 5 is complementary and is installed on the gland 5, radially be provided with screw along gland 5 and positioning sleeve 4, it is as a whole that gland 5 and positioning sleeve 4 are connected by screw 6, and the endoporus on the big end of positioning sleeve 4 diameters and the size of oil sealing 3 are complementary; Operation principle: during use, at first rear bearing cover 2 is placed on the reference column 1, can make rear bearing cover 2 place easily and guarantee the location like this, assurance rear bearing cover 2 is contained in also can be mobile at press bench on the base, then oil sealing 3 is put into the endoporus of positioning sleeve 4, positioning sleeve 4 and gland 5 are combined into one by screw 6, gland 5 evenly is pressed into the rear bearing, output shaft lid to the guiding of lower stress by reference column 1 with oil sealing 3, when positioning sleeve 4 is concordant with gland 5 upper surfaces, oil sealing 3 accurately is pressed into the regulation tram, and the work of press-fiting of oil sealing 3 is finished.
Claims (3)
1. an oil sealing press-fits accessory, it is characterized in that: the upper end of reference column (1) is provided with gland (5), is connected with positioning sleeve (4) on the gland (5).
