| description | The invention discloses a shaft sleeve capable of reducing contact stress, which comprises a shaft sleeve body, annular concave stress release grooves are respectively formed in the peripheries of the two end parts of the shaft sleeve body, and the outer side ends of the stress release grooves extend to the end surface position of the shaft sleeve body. The stress releasing grooves are formed in the peripheral faces of the two ends of the shaft sleeve body respectively, the wall thicknesses of the two ends of the shaft sleeve body can be changed by forming the stress releasing grooves, the two ends can generate tiny elastic deformation when the shaft sleeve body bears loads, and then the contact stress peak value of the two ends can be reduced; the defect that the contact stress peak at the two ends of the shaft sleeve inner hole and the contact stress peak at the middle position are obviously uneven is overcome, the problem of frictional wear between the two ends of the shaft sleeve inner hole and a shaft is |
