Turn back to Figure 23-24, input shaft 152 can have the part 151 that diameter reduces.Axially spaced in the either end of the part 151 that the shoulder 153 being shown as the first shoulder 153a and second shoulder 153b can reduce at diameter, and limit slit 155 in-between at least in part.
Turn back to Figure 17-18, the part 151 that diameter reduces is received in the groove 101 of saddleback 100.According to shown embodiment, the extension over half of the circumference of the part 151 that the arm 106 of saddleback 100 and finger piece 108 reduce around diameter, prevents input shaft 152 and saddleback 100 from separating (such as, ejecting) thus.In the assembly process of exemplary embodiment, input shaft 152 is inserted into (such as, installation, pressure etc.) in main body 122.Then, the output shaft 172 with the saddleback 100 be coupled on it is inserted in main body 122, until saddleback 100 is connected in the part 151 of the reduction of output shaft.Tolerance limit between the diameter of the part 151 reduced and the diameter of groove 101 is preferably enough tight to prevent from swinging, but also enough loose to allow input shaft 152 relative to the rotation (such as, being slidably matched) of saddleback 100.As shown in the figure, the arm 106 of saddleback 100 can be axial convergent so that saddleback 100 be inserted into input shaft 152 shoulder 153 between slit 155 in.
Spring 190 promotes output shaft 172 towards input shaft 152, promotes output gear 178 thus and engages with input gear 158.At steady state, the top 174 of output shaft 172 heads on the bottom surface 105 of the main body 102 of saddleback.According to other embodiments, the bottom of post 104 can be headed on by the bottom of the lip in hole 171 or lug.The bottom of groove 101 heads on the part 151 of diameter reduction.Therefore, the distance between the diameter of part 151 that reduces to diameter of the top 174 of output shaft 172 is restricted to the distance D (shown in Figure 19) between the bottom of the groove 101 of bottom surface 105 and saddleback 100.Therefore, the tolerance limit of accumulating between parts is greatly reduced.In addition, because the relation between input shaft 152 and output shaft is controlled by the tolerance limit of the distance D on saddleback 100 substantially, the radial position of lining 133 and 134 becomes so not most important, reduces manufacture cost thus and oil recovery enhancement.
Spring 190 promotes output gear 178 and engages with input gear 158, and this can reduce the train of gearings between gear, thus for user provides more satisfied sensation, and provides the more long duration of tooth and tooth contact.Saddleback 100 prevents together with output gear 178 from excessively closely being pushed away with input gear 158, and this can cause input shaft 152 and therefore cause handle 142 to be difficult to unsatisfactorily be rotated by user.If together with output gear 178 is excessively closely pushed away with input gear 158, user also can feel wheel tooth unsatisfactorily.Therefore, saddleback 100 improves gear alignment by the tolerance limit simplifying accumulation, so that control the position of the point of contact between output gear 178 and the tooth of input gear 158 better.
In addition, the power of spring 190 can be configured such that output gear 178 and input gear 158 keep together by spring force when static, provide the friction of the increase of unintentional rotation that can stop handle thus.But when input shaft 152 is deliberately rotated, spring 190 can be compressed (such as, be obedient to, be out of shape (give) etc.), this allows output gear 178 slightly to depart from the tooth of input gear 158, to allow the point cantact between gear.
According to some embodiments, the axial length L (shown in Figure 19) of saddleback 100 can be configured to the axial length L being similar to the part 151 that the diameter of (but being slightly less than) shoulder between 153a, 153b reduces ' (shown in Figure 24).Such as, the tolerance limit between length L and length L ' can be slidably matched, to arrange input shaft 152 relative to output shaft 172 further, and therefore arranges input gear 158, and therefore arranges output gear 178.According to other embodiments, the part 151 of the diameter reduction of input shaft 152 can not have the diameter (such as, see input shaft 52) of reduction, and the size of the groove 101 of saddleback 100 can be set to hold larger diameter.
With reference to Figure 25-26, packing ring 191 can be disposed between spring 190 and output shaft 172.Packing ring 191 can be made up of any suitable (preferred low friction) material, such as nylon, polyethylene or polyoxymethylene (such as, Celcon, Delrin, Hostaform etc.).Packing ring 191 is convenient to the rotation of output shaft 172 relative to spring 190, reduces wear thus and improves user's sensation.
With reference to Figure 27, show the lining 182 according to exemplary embodiment.Lining 182 is shown as including inner ring 183, and inner ring 183 limits the hole 181 being configured to receive output shaft 172.Multiple spoke 184 axially stretches out from inner ring 183.According to shown embodiment, multipair spoke 184 is connected by external member 185.Lining 182 can be made up of any suitable (preferred low friction) material, such as nylon, polyethylene or polyoxymethylene (such as, Celcon, Delrin, Hostaform etc.).
Lining 182 is installed on output shaft 172, preferably have the rotation being slidably matched to allow to have limited swing, and then output shaft assembly is installed to main body 122, lining 182 is pressed in main body 122.Rib 186 along the axial convergent formed of external member 185 is convenient to the joint between lining 182 and main body 122.Lining 182 can be supported by flange 180 (shown in Figure 21).
Spoke 184 and external member 185 are configured to serve as spring (such as, in order to provide radial spring force), allow output shaft 172 automatic aligning thus, such as, be axially aligned by the post 104 of saddleback 100, the interaction between output gear 178 and input gear 158 and/or valve rod 206 or ABAP Adapter 208, but not be aligned relative to main body 122.The automatic aligning ability of lining 182 decreases the shake of output shaft 172, the concentricity of output shaft can be promoted, and promote engaging of input gear 158 and output gear 178, reducing thus may the unsatisfied gear clearance of other users (such as, rocking).
In addition, because the part 151 that saddleback 100 can reduce relative to diameter rotates in a circumferential direction, and lining 182 provides spring action, so output shaft 172 can be directed in the position mode of non-vertical, to compensate valve rod 206 or unjustified between ABAP Adapter 208 and input shaft 152.
