Abstract
The utility model discloses an embedded shaft type double row ball bearing, including outer lane, embedded axle, ball frame, ball and sealing washer, it makes the integral type structure with two suits of single -row ball bearing, axle and overcoats, reduces sum of errors assembly tolerance, the design of biserial ball, and two are listed as the ball and become angular contact form back -to -back in actually assembling, have eliminated axial internal clearance to axial float when solving two sets of bearings and using side by side, the shake of elimination equipment.
Description
Technical field
The utility model belongs to field of bearings, relates in particular to a kind of embedded shaft type two row ball bearing.
Background technique
Bearing is a kind of important spare part in contemporary machinery.Its major function is supported mechanical solid of rotation, reduces the friction factor in its movement process, and ensures its rotating accuracy.
Need two cover bearings and axle to use side by side (as shown in Figure 1) in some occasions, because two cover bearings are at internal diameter, inconsistent on the main assembly parameter such as external diameter play, even exist and do not mate, therefore when reality uses, equipment performance instability can be there is, the situations such as equipment shake.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of embedded shaft type two row ball bearing is provided, two cover single-row ball bearing, axle and overcoats are made of one formula structure by it, reduce error and build-up tolerance, double row ball designs, and in practical set, two row balls become angle contacting form back-to-back, eliminate axial internal clearance, to solve axial float when two cover bearings use side by side, abatement apparatus is shaken.
The utility model realizes by the following technical solutions:
A kind of embedded shaft type two row ball bearing, comprises outer ring, embedded axle, ball rack, ball and seal ring,
Described embedded axle comprises the minor diameter shaft part at two ends and the major diameter shaft part of intermediate portion, and described minor diameter shaft part and major diameter shaft part are structure as a whole; Embedded axle and outer ring are coaxially arranged; Described ball rack comprises the first ball rack and the second ball rack, and the first ball rack and the second ball rack are arranged between embedded axle and outer ring in parallel to each other, and the first ball rack and the second ball rack with the vertical bisector of embedded axle for bisector is symmetrical; Described ball comprises first row ball and secondary series ball, and first row ball and secondary series ball are arranged in the first ball rack and the second ball rack respectively; Described seal ring comprises the first seal ring and the second seal ring, and it is symmetricly set between outer ring and embedded axle two ends.
In technique scheme, the end face of described major diameter shaft part and the end face of outer ring are at same plane.
In technique scheme, the spacing of described first row ball and secondary series ball is 1/2nd of outer ring length.
Two cover single-row ball bearing, axle and overcoats are made of one formula structure by the utility model, reduce error and build-up tolerance, double row ball designs, in practical set, two row balls become angle contacting form back-to-back, eliminate axial internal clearance, to solve axial float when two cover bearings use side by side, abatement apparatus is shaken.
Accompanying drawing explanation
